RMS Olympic
–
RMS Olympic was a transatlantic ocean liner, the lead ship of the White Star Lines trio of Olympic-class liners. Unlike her younger sister ships, Olympic had a long career and this included service as a troopship during the First World War, which gained her the nickname Old Reliable. Olympic was the largest ocean liner in the world for two periods during 1911–13, interrupted only by the tenure of the slightly larger Titanic. Olympic also retained the title of the largest British-built liner until RMS Queen Mary was launched in 1934, by contrast with Olympic, the other ships in the class, Titanic and Britannic, did not have long service lives. Built in Belfast, Ireland, the RMS Olympic was the first of the three Olympic-class ocean liners – the others were RMS Titanic and HMHS Britannic. They were by far the largest vessels of the British shipping company White Star Lines fleet, the company sought an upgrade in their fleet primarily in response to the Cunard giants but also to replace their largest and now outclassed ships from 1890, SS Teutonic and SS Majestic. The former was replaced by Olympic while Majestic was replaced by Titanic, Majestic would be brought back into her old spot on White Stars New York service after Titanics loss. The ships were constructed by the Belfast shipbuilders Harland and Wolff, cost considerations were relatively low on the agenda and Harland and Wolff was authorised to spend what it needed on the ships, plus a five percent profit margin. In the case of the Olympic-class ships, a cost of £3 million for the first two ships was agreed plus extras to contract and the five percent fee. Harland and Wolff put their leading designers to work designing the Olympic-class vessels, carlisles responsibilities included the decorations, equipment and all general arrangements, including the implementation of an efficient lifeboat davit design. On 29 July 1908, Harland and Wolff presented the drawings to J. Bruce Ismay, Ismay approved the design and signed three letters of agreement two days later authorising the start of construction. At this point the first ship – which was later to become Olympic – had no name, Titanic was based on a revised version of the same design and was given the number 401. Bruce Ismays father Thomas Henry Ismay had previously planned to build a ship named Olympic as a ship to Oceanic. The senior Ismay died in 1899 and the order for the ship was cancelled, construction of Olympic began three months before Titanic to ease pressures on the shipyard. Several years would pass before Britannic would be launched, in order to accommodate the construction of the class, Harland and Wolff upgraded their facility in Belfast, the most dramatic change was the combining of three slipways into two larger ones. Olympics keel was laid in December 1908 and she was launched on 20 October 1910 and her hull was repainted black following the launch. The first-class passengers enjoyed luxurious cabins, and some were equipped with private bathrooms, first-class passengers could have meals in the ships large and luxurious dining saloon or in the more intimate A La Carte Restaurant. The second-class facilities included a room, a library, a spacious dining room

Falls of Clyde (ship)
–
Falls of Clyde is the last surviving iron-hulled, four-masted full-rigged ship, and the only remaining sail-driven oil tanker. Designated a U. S. National Historic Landmark in 1989, she is now a museum ship in Honolulu and she is currently not open to the public. In September 2008, ownership was transferred to a new organization, the Friends of Falls of Clyde. Efforts to raise $1.5 million to get the ship into drydock have not succeeded as of 2015, an additional $30 million may be needed to fully restore the ship. In August,2016, the Harbors Division of the State of Hawaii impounded the ship, efforts are underway to convince the Governor to preserve the ship, including an online petition. Falls of Clyde was built in 1878 by Russell and Company in Port Glasgow, Inverclyde, Scotland, launched as the first of nine iron-hulled four-masted ships for Wright and Breakenridges Falls Line. She was named after the Falls of Clyde, a group of waterfalls on the River Clyde and her maiden voyage took her to Karachi, now in Pakistan, and her first six years were spent engaged in the India trade. She then became a tramp pursuing general cargo such as lumber, jute, cement, and wheat from ports in Australia, California, India, New Zealand, and the British Isles. To economize on crew, Matson rigged Falls of Clyde down as a barque, at the same time, he added a deckhouse, charthouse, and rearranged the after quarters to accommodate paying passengers. From 1899 to 1907, she made over sixty voyages between Hilo, Hawaii, and San Francisco, California, carrying general merchandise west, sugar east and she developed a reputation as a handy, fast, and commodious vessel, averaging 17 days each way on her voyages. In 1907, the Associated Oil Company bought Falls of Clyde, ten large steel tanks were built into her hull, and a pump room, boiler and generator fitted forward of an oil-tight bulkhead. In this configuration she brought kerosene to Hawaii and returned to California with molasses for cattle feed, in 1927, she was sold to the General Petroleum Company, her masts cut down, and converted into a floating fuel depot in Alaska. In 1959 she was purchased by William Mitchell, who towed her to Seattle, Washington, in 1963, the bank holding the mortgage on Falls of Clyde decided to sell her to be sunk as part of a breakwater at Vancouver, British Columbia. Kortum and Klebingat aroused interest in the ship in Hawaii, at the end of October 1963, Falls of Clyde was taken under tow bound for Honolulu. Falls of Clyde was given to the Bishop Museum and opened to the public in 1968, in 1970 the grandson of original 19th century designer William Lithgow was engaged to assist in her restoration as a full-rigged ship. Support came from Sir William Lithgow, the shipbuilder and industrialist, whose Port Glasgow shipyard donated new steel masts, in 1973 the ship was entered into the National Register of Historic Places, and declared a U. S. National Historic Landmark in 1989. The ship is now in poor condition, causes of the deterioration of the ship are multiple. The ship has not been dry docked for a long time, preventive maintenance was not performed, although it would have been relatively inexpensive

Compartment (ship)
–
A compartment is a portion of the space within a ship defined vertically between decks and horizontally between bulkheads. It is analogous to a room within a building, and may provide watertight subdivision of the ships hull important in retaining buoyancy if the hull is damaged, subdivision of a ships hull into watertight compartments is called compartmentation. Watertight subdivision limits loss of buoyancy and freeboard in the event of damage, most ships have some pumping capacity to remove accumulated water from the bilges, but a steel ship with no watertight subdivision will sink if water accumulates faster than pumps can remove it. Standards of watertight subdivision assume no dewatering capability, although kept in working order may provide an additional measure of safety in the event of minor leaks. The most common watertight subdivision is accomplished with transverse bulkheads dividing the elongated hull into a number of watertight floodable lengths, early watertight subdivision tested with hoses sometimes failed to withstand the hydrostatic pressure of an adjoining flooded compartment. Effective watertight subdivision requires these transverse bulkheads to be watertight and structurally sound. A ship will sink if the transverse bulkheads are so far apart that flooding a single compartment would consume all the ships reserve buoyancy. Aside from the protection of machinery, or areas most susceptible to damage, such a ship would be no better than a ship without watertight subdivision. A ship able to remain afloat with any two compartments flooded is called a three-compartment ship, and will withstand damage to one transverse bulkhead, wartime experience with torpedo damage indicated the typical damage diameter of 35 feet defined a practical minimum distance for transverse bulkhead spacing. Three types of doors are used between compartments. A closed weathertight door can seal out spray and periodic minor flow over weather decks and these outward opening doors are useful at weather deck entrances to compartments above the main deck. Joiner doors are similar to doors used in conventional buildings ashore and they afford privacy and temperature control for compartments formed by non-structural bulkheads within the ships hull. Compartments are identified by the forming the floor of that compartment. Different types of ships have different deck naming conventions, passenger ships often use letters of the alphabet sequentially down from A deck above B deck, and B deck above C deck, and so forth. Another popular naming convention is numbering the main deck 1, the deck below it 2, and the deck below that the third deck, the United States Navy has used the latter convention in a compartment numbering system since 1949. The USN system identifies each compartment by a four-part code separated by hyphens, the centerline position code is zero for a compartment on the ships centerline, odd numbers for compartments entirely to starboard of the centerline, and even for compartments entirely to port. For compartments sharing the same deck and forward frame, the first two parts of the code are identical, and the part of the code is numbered outward from the centerline. For example, four main compartments at frame 90 would be 1-90-1-L inboard and 1-90-3-L outboard on the starboard side of the ship and 1-90-2-L inboard

Hull (watercraft)
–
The hull is the watertight body of a ship or boat. Above the hull is the superstructure and/or deckhouse, where present, the line where the hull meets the water surface is called the waterline. The structure of the hull varies depending on the vessel type, the uppermost continuous deck may be called the upper deck, weather deck, spar deck, main deck, or simply deck. The particular name given depends on the type of ship or boat. In a typical wooden sailboat, the hull is constructed of wooden planking, supported by transverse frames and bulkheads, often but not always there is a centerline longitudinal member called a keel. In fiberglass or composite hulls, the structure may resemble wooden or steel vessels to some extent, in many cases, composite hulls are built by sandwiching thin fiber-reinforced skins over a lightweight but reasonably rigid core of foam, balsa wood, impregnated paper honeycomb or other material. The shape of the hull is entirely dependent upon the needs of the design, shapes range from a nearly perfect box in the case of scow barges, to a needle-sharp surface of revolution in the case of a racing multihull sailboat. Hulls come in varieties and can have composite shape, but are grouped primarily as follows. Examples are the flat-bottom, v-bottom, and multi-bottom hull and these types have at least one pronounced knuckle throughout all or most of their length. These hull shapes all have smooth curves, examples are the round bilge, semi-round bilge, and s-bottom hull. After this they can be categorized as, Displacement The hull is supported exclusively or predominantly by buoyancy, vessels that have this type of hull travel through the water at a limited rate that is defined by the waterline length. They are often, though not always, heavier than planing types, planing The planing hull form is configured to develop positive dynamic pressure so that its draft decreases with increasing speed. The dynamic lift reduces the surface and therefore also the drag. They are sometimes flat-bottomed, sometimes V-bottomed and more rarely, round-bilged, the most common form is to have at least one chine, which makes for more efficient planing and can throw spray down. Planing hulls are more efficient at speeds, although they still require more energy to achieve these speeds. An effective planing hull must be as light as possible with flat surfaces that are consistent with sea keeping. Sail boats that plane must also sail efficiently in displacement mode in light winds, semi-displacement, or semi-planing The hull form is capable of developing a moderate amount of dynamic lift, however, most of the vessels weight is still supported through buoyancy. At present, the most widely used form is the round bilge hull, in the inverted bell shape of the hull, with a smaller payload the waterline cross-section is less, hence the resistance is less and the speed is higher

Ship
–
Historically, a ship was a sailing vessel with at least three square-rigged masts and a full bowsprit. Ships are generally distinguished from boats, based on size, shape, Ships have been important contributors to human migration and commerce. They have supported the spread of colonization and the trade, but have also served scientific, cultural. After the 16th century, new crops that had come from, Ship transport is responsible for the largest portion of world commerce. As of 2016, there were more than 49,000 merchant ships, of these 28% were oil tankers, 43% were bulk carriers, and 13% were container ships. Military forces operate vessels for naval warfare and to transport and support forces ashore, the top 50 navies had a median fleet of 88 surface vessels each, according to various sources. There is no definition of what distinguishes a ship from a boat. Ships can usually be distinguished from boats based on size and the ability to operate independently for extended periods. A legal definition of ship from Indian case law is a vessel that carries goods by sea, a common notion is that a ship can carry a boat, but not vice versa. American and British 19th Century maritime law distinguished vessels from other craft, ships and boats fall in one legal category, a number of large vessels are usually referred to as boats. Other types of vessel which are traditionally called boats are Great Lakes freighters, riverboats. Though large enough to carry their own boats and heavy cargoes, in most maritime traditions ships have individual names, and modern ships may belong to a ship class often named after its first ship. The first known vessels date back about 10,000 years ago, the first navigators began to use animal skins or woven fabrics as sails. Affixed to the top of a pole set upright in a boat and this allowed men to explore widely, allowing for the settlement of Oceania for example. By around 3000 BC, Ancient Egyptians knew how to assemble wooden planks into a hull and they used woven straps to lash the planks together, and reeds or grass stuffed between the planks helped to seal the seams. Sneferus ancient cedar wood ship Praise of the Two Lands is the first reference recorded to a ship being referred to by name, the ancient Egyptians were perfectly at ease building sailboats. A remarkable example of their skills was the Khufu ship. Aksum was known by the Greeks for having seaports for ships from Greece, a panel found at Mohenjodaro depicted a sailing craft

Boat
–
A boat is a watercraft of a large range of sizes designed to float, plane, work or travel on water. Small boats are found on inland waterways or in protected coastal areas. However, boats such as the whaleboat were designed for operation from a ship in an offshore environment, in naval terms, a boat is a vessel small enough to be carried aboard another vessel. Another less restrictive definition is a vessel that can be lifted out of the water, some definitions do not make a distinction in size, as bulk freighters 1,000 feet long on the Great Lakes are called oreboats. For reasons of tradition, submarines are usually referred to as boats rather than ships, regardless of their size. Ships are generally distinguished from boats based on their size, shape. Boats have a variety of shapes, sizes and construction methods due to their intended purpose. Canoe-type boats have used since prehistoric times and various versions are used throughout the world for transportation. Fishing boats vary widely in style partly to local conditions. Pleasure boats include ski boats, pontoon boats, and sailboats, house boats may be used for vacationing or long-term housing. Small boats can provide transport or convey cargo to and from large ships, lifeboats have rescue and safety functions. Boats can be powered by power, wind power and motor power. Dugouts are the oldest type of boats found by archaeologists, the earliest boats are thought to have been logboats, and the oldest boats found by archaeological excavation date from around 7, 000–10,000 years ago. The oldest recovered boat in the world is the Pesse canoe and this canoe is exhibited in the Drents Museum in Assen, Netherlands. Other very old dugout boats have also been recovered, rafts have operated for at least 8,000 years. A7, 000-year-old seagoing reed boat has been found in Kuwait, boats were used between 4000 and 3000 BC in Sumer, ancient Egypt and in the Indian Ocean. Boats played an important role in the commerce between the Indus Valley Civilization and Mesopotamia, evidence of varying models of boats has also been discovered at various Indus Valley archaeological sites. Uru craft originate in Beypore, a village in south Calicut, Kerala and this type of mammoth wooden ship was constructed using teak, without any iron, and had a transport capacity of 400 tonnes

Tension (physics)
–
Tension is the opposite of compression. At the atomic level, when atoms or molecules are pulled apart each other and gain potential energy with a restoring force still existing. Each end of a string or rod under such tension will pull on the object it is attached to, to restore the string/rod to its relaxed length. In physics, tension, as a force, as an action-reaction pair of forces. The ends of a string or other object transmitting tension will exert forces on the objects to which the string or rod is connected and these forces due to tension are also called passive forces. Tension in a string is a scalar quantity. A string or rope is often idealized as one dimension, having length but being massless with zero cross section. If there are no bends in the string, as occur with vibrations or pulleys, then tension is a constant along the string, by Newtons Third Law, these are the same forces exerted on the ends of the string by the objects to which the ends are attached. If the string curves around one or more pulleys, it still have constant tension along its length in the idealized situation that the pulleys are massless and frictionless. A vibrating string vibrates with a set of frequencies that depend on the strings tension and these frequencies can be derived from Newtons laws of motion. Each microscopic segment of the string pulls on and is pulled upon by its neighboring segments, tension = τ where x is the position along the string. If the string has curvature, then the two pulls on a segment by its two neighbors will not add to zero, and there will be a net force on that segment of the string, causing an acceleration. With solutions that include the various harmonics on a stringed instrument, tension is also used to describe the force exerted by the ends of a three-dimensional, continuous material such as a rod or truss member. Such a rod elongates under tension, a system is in equilibrium when the sum of all forces is zero. ∑ F → =0 For example, consider a system consisting of an object that is being lowered vertically by a string with tension, T, at a constant velocity. ∑ F → = T → + m g → =0 A system has a net force when a force is exerted on it. Acceleration and net force always exist together, ∑ F → ≠0 For example, consider the same system as above but suppose the object is now being lowered with an increasing velocity downwards therefore there exists a net force somewhere in the system. In this case, negative acceleration would indicate that | m g | > | T |

Compression (physics)
–
It is contrasted with tension or traction, the application of balanced outward forces, and with shearing forces, directed so as to displace layers of the material parallel to each other. The compressive strength of materials and structures is an important engineering consideration, in uniaxial compression the forces are directed along one direction only, so that they act towards decreasing the objects length along that direction. If the stress vector itself is opposite to x, the material is said to be under compression or pure compressive stress along x. In a solid, the amount of compression depends on the direction x. If the stress vector is purely compressive and has the same magnitude for all directions and this is the only type of static compression that liquids and gases can bear. In a mechanical longitudinal wave, or compression wave, the medium is displaced in the waves direction, when put under compression, every material will suffer some deformation, even if imperceptible, that causes the average relative positions of its atoms and molecules to change. The deformation may be permanent, or may be reversed when the compression forces disappear, in the latter case, the deformation gives rise to reaction forces that oppose the compression forces, and may eventually balance them. Liquids and gases cannot bear steady uniaxial or biaxial compression, they will deform promptly and permanently, however they can bear isotropic compression, and may be compressed in other ways momentarily, for instance in a sound wave. The deformation may not be uniform and may not be aligned with the compression forces, what happens in the directions where there is no compression depends on the material. Most materials will expand in those directions, but some special materials will remain unchanged or even contract, by inducing compression, mechanical properties such as compressive strength or modulus of elasticity, can be measured. Compression machines range from small table top systems to ones with over 53 MN capacity. Gases are often stored and shipped in highly compressed form, to save space, slightly compressed air or other gases are also used to fill balloons, rubber boats, and other inflatable structures. Compressed liquids are used in equipment and in fracking. In internal combustion engines the explosive mixture gets compressed before it is ignited, in the Otto cycle, for instance, the second stroke of the piston effects the compression of the charge which has been drawn into the cylinder by the first forward stroke. This compression, moreover, obviates the shock which would otherwise be caused by the admission of the steam for the return stroke.

Container ship
–
Container ships are cargo ships that carry all of their load in truck-size intermodal containers, in a technique called containerization. They are a means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo. Container ship capacity is measured in equivalent units. Typical loads are a mix of 20-foot and 40-foot ISO-standard containers, today, about 90% of non-bulk cargo worldwide is transported by container, and modern container ships can carry over 19,000 TEU. Container ships now rival crude oil tankers and bulk carriers as the largest commercial vessels on the ocean, there are two main types of dry cargo, bulk cargo and break bulk cargo. Bulk cargoes, like grain or coal, are transported unpackaged in the hull of the ship, break-bulk cargoes, on the other hand, are transported in packages, and are generally manufactured goods. Before the advent of containerization in the 1950s, break-bulk items were loaded, lashed, unlashed and unloaded from the one piece at a time. However, by grouping cargo into containers,1,000 to 3,000 cubic feet of cargo, or up to about 64,000 pounds, is moved at once and each container is secured to the ship once in a standardized way. Containerization has increased the efficiency of moving traditional break-bulk cargoes significantly, reducing shipping time by 84%, in 2001, more than 90% of world trade in non-bulk goods was transported in ISO containers. In 2009, almost one quarter of the dry cargo was shipped by container. The first ships designed to carrying standardized load units were use in the late 18th century in England, in 1766 James Brindley designed the box boat Starvationer with 10 wooden containers, to transport coal from Worsley Delph to Manchester by Bridgewater Canal. Before the Second World War first container ships were used to carrying baggages of the passenger train from London to Paris, Golden Arrow/Fleche dOr. These containers were loaded in London or Paris and carried to ports, Dover or Calais, on cars in the UK. The earliest container ships after the Second World War were converted to tankers, in 1951, the first purpose-built container vessels began operating in Denmark, and between Seattle and Alaska. The first commercially successful container ship was Ideal X, a T2 tanker, owned by Malcom McLean, in 1955, McLean built his company, McLean Trucking into one of United States biggest freighter fleets. In 1955, he purchased the small Pan Atlantic Steamship Company from Waterman Steamship, on April 26,1956, the first of these rebuilt container vessels, Ideal X, left the Port Newark in New Jersey and a new revolution in modern shipping resulted. Container vessels eliminate the individual hatches, holds and dividers of the general cargo vessels. The hull of a container ship is a huge warehouse divided into cells by vertical guide rails

Capstan (nautical)
–
A capstan is a vertical-axled rotating machine developed for use on sailing ships to apply force to ropes, cables, and hawsers. The principle is similar to that of the windlass, which has a horizontal axle, both device and word are considered Spanish inventions. In its earliest form, the capstan consisted of a timber mounted vertically through a structure which was free to rotate. Levers, known as bars, were inserted through holes at the top of the timber, a rope wrapped several turns around the drum was thus hauled upon. A rudimentary ratchet was provided to hold the tension, the ropes were always wound in a clockwise direction. Capstans evolved to consist of a drum or barrel mounted on an iron axle. Two barrels on a common axle were used frequently to allow men on two decks to apply force to the bars, later capstans were made entirely of iron, with gearing in the head providing a mechanical advantage when the bars were pushed counterclockwise. One form of capstan was connected by a shaft and gears to an anchor windlass on the deck below, on riverine vessels, the capstan was sometimes cranked by steam power. Modern capstans are powered electrically, hydraulically, pneumatically, or via an internal combustion engine, typically, a gearbox is used which trades reduced speed, relative to the prime mover, for increased torque. In yachting terminology, a winch functions on the principle as a capstan. However, in applications, the term winch generally implies a machine which stores the rope on a drum. Hydraulically powered capstans were used in railway goods yards for shunting. One example was Broad Street goods station in London, the yard was on a deck above some warehouses, and the deck was not strong enough to carry a locomotive, so ropes and capstans were used instead

Cleat (nautical)
–
In nautical contexts, a cleat is a device for securing a rope. A cam cleat in one or two spring-loaded cams pinch the rope, allowing the rope to be adjusted easily, and quickly released when under load. A jam cleat in which the line is pinched in a v-shaped slot, a clam cleat in which the rope is held between two fluted stationary pieces. Such a cleat vaguely resembles two halves of a shell held back to back. It is more compact than a cam cleat, but the rope is less easily released under load, a cleat hitch is a knot used to secure a rope to a cleat. Winch, which may incorporate a cleat of sorts Belaying pin Ashley, the Ashley Book of Knots, New York, Doubleday, p. Dust jacket, ISBN 0-385-04025-3 Grog

Bollard
–
A bollard is a sturdy, short, vertical post. The term is related to bole, meaning a tree trunk. The earliest citation given by the Oxford English Dictionary dates from 1844, previously, simpler terms such as post appear to have been used. The Norman-French name Boulard may be related, from the 17th and 18th centuries, old cannon were often used as bollards on quaysides to help moor ships alongside. The cannon would be buried in the ground muzzle-first to approximately half or two-thirds of their length, such cannon can still occasionally be found. Bollards from the 19th century were purpose-made, but often inherited a similar cannon shape. Wooden posts were used for traffic management from at least the beginning of the 18th century. Similar posts can be seen in historic paintings and engravings. In the Netherlands, the Amsterdammertjes of Amsterdam were first erected in the 19th century and they became popular symbols of the city, but they are now gradually being removed and replaced with elevated sidewalks. Mooring bollards are seldom exactly cylindrical, but typically have a diameter near the top to discourage mooring warps from coming loose. Single bollards sometimes include a cross rod to allow the lines to be bent into a figure eight. Small mushroom-bollards are found on lock approaches for advancing boats waiting for lock access, according to Trafficcalming. org, bollards can be used, either to control traffic intake size by limiting movements, or to control traffic speed by narrowing the available space. Israels Transportation Research Institute found that putting bollards at highway exits to control traffic also reduced accidents, bollards may also be used to enclose car-free zones. Bollards and other furniture are used to control overspill parking onto sidewalks. Also referred to as delineators, the bases are made from recycled rubber. The term T-top bollards refers to the T-bar moulded into the top for tying tape, bollards are regarded as an economical and safe delineation system for motorways and busy arterial roads, and, in conjunction with plastic tape, for pedestrian control. Traffic bollards used in the US are very similar to devices throughout the UK, with the following exceptions. In addition, the traffic bollard also has a yellow diamond below the Keep Right symbol instead of a yellow shield, unlike many existing traffic bollards found in the UK, most new modern traffic bollards installed along roadways today are made of materials that make them completely collapsible

RMS Queen Mary 2
–
RMS Queen Mary 2 is a transatlantic ocean liner. She is the major ocean liner built for Cunard Line since Queen Elizabeth 2 in 1969. The new ship was named Queen Mary 2 by Queen Elizabeth II in 2004 after the first 1936 namesake ship RMS Queen Mary, Queen Mary was in turn named after Mary of Teck, consort of King George V. With the retirement of Queen Elizabeth 2 in 2008, Queen Mary 2 is the transatlantic ocean liner in line service between Southampton and New York, which operates for part of each year. The ship is used for cruising, including an annual world cruise. The ship was designed by a team of British naval architects led by Stephen Payne, at the time of her construction, Queen Mary 2 was the longest passenger ship ever built, and with her gross tonnage of 148,528 also the largest. She no longer holds this distinction after the construction of Royal Caribbean Internationals 154,407 GT Freedom of the Seas in April 2006, Queen Mary 2 was intended for routine crossings of the Atlantic Ocean, and was therefore designed differently from many other passenger ships. The ships final cost was approximately $300,000 US per berth, expenses were increased by the high quality of materials, and having been designed as an ocean liner, she required 40% more steel than a standard cruise ship. Queen Mary 2 has a speed of just over 30 knots. Instead of the configuration found on many ships, Queen Mary 2 uses integrated electric propulsion to achieve her top speed. This uses gas turbines to augment the power generated from the ships diesels, some of Queen Mary 2s facilities include fifteen restaurants and bars, five swimming pools, a casino, a ballroom, a theatre, and the first planetarium at sea. Queen Mary 2 is the flagship of Cunard Line, the ship was constructed for eventual replacement of the aging Queen Elizabeth 2, the Cunard flagship from 1969 to 2004 and the last major ocean liner built before the construction of Queen Mary 2. Queen Mary 2 had the Royal Mail Ship title conferred on her, as a gesture to Cunards history, the spaces for these prime movers are also split, and controls are also backed up, with the intention of preventing a single failure from disabling the ship. Queen Mary 2s 30-knot open ocean speed sets the ship apart from ships, such as MS Oasis of the Seas. While the hull of a ship will typically have a block coefficient of 0.73 Queen Mary 2 is more fine-lined. In December 1998, Cunard released details of Project Queen Mary, harland and Wolff of Northern Ireland, Aker Kværner of Norway, Fincantieri of Italy, Meyer Werft of Germany, and Chantiers de lAtlantique of France were invited to bid on the project. The contract was signed with Chantiers de lAtlantique, a subsidiary of Alstom. This was the yard that built Cunards former rivals, the SS Normandie

Ocean liner
–
An ocean liner is a ship designed to transport people from one seaport to another along regular long-distance maritime routes according to a schedule. Liners may also carry cargo or mail, and may sometimes be used for other purposes, cargo vessels running to a schedule are sometimes called liners. The category does not include ferries or other vessels engaged in trading, nor dedicated cruise ships where the voyage itself. Nor does it include tramp steamers, even those equipped to handle limited numbers of passengers, some shipping companies refer to themselves as lines and their container ships, which often operate over set routes according to established schedules, as liners. Ocean liners are usually built with a high freeboard to withstand rough seas. Additionally, they are designed with thicker hull plating than is found on cruise ships. Once the dominant form of travel between continents, ocean liners were rendered obsolete by the emergence of long-distance aircraft after World War II. Advances in automobile and railway also played a role. As of 2015, RMS Queen Mary 2 was the ship still in service as an ocean liner. Ocean liners were the mode of intercontinental travel for over a century. In addition to passengers, liners carried mail and cargo, ships contracted to carry British Royal Mail used the designation RMS. Liners were also the way to move gold and other high-value cargoes. The busiest route for liners was on the North Atlantic with ships travelling between Europe and North America and it was on this route that the fastest, largest and most advanced liners travelled. Shipping lines are companies engaged in shipping passengers and cargo, often on established routes and schedules, regular scheduled voyages on a set route are called line voyages and vessels trading on these routes to a timetable are called liners. The alternative to liner trade is tramping whereby vessels are notified on a basis as to the availability of a cargo to be transported. The term ocean liner has come to be used interchangeably with passenger liner, beginning at the advent of the Jet Age, where transoceanic ship service declined, a gradual transition from passenger ships as mean of transportation to nowadays cruise ships started. In order for ocean liners to remain profitable, cruise lines have modified some of them to operate on routes, such as the Queen Elizabeth 2. The Italian Lines SS Michelangelo and SS Raffaello, the last ocean liners to be primarily for crossing the North Atlantic

Cruise ship

Transportation is not the only purpose of cruising, particularly on cruises that return passengers to their originating port, with the ports of call usually in a specified region of a continent. There are even cruises to nowhere or nowhere voyages where the ship makes 2–3 night round trips without any ports of call, by contrast, dedicated transport oriented ocean liners do line voyages and typically transport passengers from one point to another, rather than on round trips. The gradual evolution of passenger ship design from ocean liners to cruise ships has seen passenger cabins shifted from inside the hull to the superstructure with private verandas, the distinction between ocean liners and cruise ships has blurred, particularly with respect to deployment. Larger cruise ships have also engaged in longer trips such as transoceanic voyages which may not return to the port for months. Some former ocean liners operate as cruise ships, such as Marco Polo, the only dedicated transatlantic ocean liner in operation as a liner of December 2013 is Queen Mary 2 of the Cunard fleet. The industrys rapid growth has seen nine or more newly built ships catering to a North American clientele added every year since 2001, smaller markets, such as the Asia-Pacific region, are generally serviced by older ships. These are displaced by new ships in the growth areas. The worlds largest cruise ship is currently Royal Caribbean Internationals Harmony of the Seas beating her sister ships by about 2.15 meters, the birth of leisure cruising began with the formation of the Peninsular & Oriental Steam Navigation Company in 1822. The company started out as a line with routes between England and the Iberian Peninsula, adopting the name Peninsular Steam Navigation Company. It won its first contract to deliver mail in 1837, in 1840, it began mail delivery to Alexandria, Egypt, via Gibraltar and Malta. The company was incorporated by Royal Charter the same year, becoming the Peninsular, P&O first introduced passenger cruising services in 1844, advertising sea tours to destinations such as Gibraltar, Malta and Athens, sailing from Southampton. The forerunner of modern cruise holidays, these voyages were the first of their kind, the company later introduced round trips to destinations such as Alexandria and Constantinople. It underwent a period of expansion in the latter half of the 19th century, commissioning larger. Some sources mention Francesco I, flying the flag of the Kingdom of the Two Sicilies and she was built in 1831 and sailed from Naples in early June 1833, preceded by an advertising campaign. The cruise ship was boarded by nobles, authorities, and royal princes from all over Europe, however, it was restricted to the aristocracy of Europe and was not a commercial endeavour. Christian Wilhelm Allers published an account of it as Backschisch. The first vessel built exclusively for cruising, was Prinzessin Victoria Luise of Germany, designed by Albert Ballin. The ship was completed in 1900, the practice of luxury cruising made steady inroads on the more established market for transatlantic crossings

Lido
–
A lido is a public outdoor swimming pool and surrounding facilities, or part of a beach where people can swim, lie in the sun, or participate in water sports. On a cruise ship or ocean liner, the deck with outdoor pools and surrounding facilities is often designated the lido deck. Lido is an Italian word for beach and forms part of the name of several Italian seaside towns known for their beach, e. g. Lido di Venezia. Possibly, the term found its way into English from English visitors returning from the Lido di Venezia, history of lidos in the United Kingdom List of long course swimming pools in the United Kingdom Notes Sources Smith, Janet.

Princess Cruises
–
Princess Cruises is a cruise line based in Santa Clarita, California, in the United States and incorporated in Bermuda. It is part of Holland America Group, which controls the three Carnival brands based on the West Coast of the United States, the lines ships cruise worldwide and are marketed to both American and international passengers. The company was famous by The Love Boat TV series, in which its ship. In 1969, the Princess Italia was used on Alaskan cruises from San Francisco, but by 1973, the charter was canceled, Princesss third charter ship was none other than Costas Carla C. Originally, Compagnie Générale Transatlantiques SS Flandre, the ship had been purchased by Costa in the late 1960s and given a major rebuilding. The two ships that were to be featured heavily in the television series The Love Boat were built in 1971 at Nordseewerke for Flagship Cruises and originally named the Sea Venture and Island Venture. In 1974, P&O purchased them for their Princess division, and they served as the Island Princess and she was initially based in Australia as a P&O ship until 1981 when her role there was taken over by the Oriana. After that, she alternated between P&O and Princess colours as she moved between fleets, the Sea Princess returned to the P&O UK fleet permanently and in 1995 and was renamed MV Victoria to allow a then-new Princess ship to be named Sea Princess. The ship served in P&O Cruises fleet as the Artemis until 2011, the Swan Hellenic Cruiseship Minerva II, originally built as the Renaissance Cruises R8 was renamed Royal Princess in 2007 after an extensive refit during a drydock in Gibraltar. In 1986, P&O Princess Cruises acquired Tour Alaska, which operated on the Alaska Railroad, based in Anchorage, Alaska, Princess Tours now operates ten luxury railcars with full-service scenic tours of Denali and can accommodate over 700 passengers per day. P&O Princess Cruises acquired Sitmar Line in 1988 and transferred all of its tonnage to Princess. The Dawn Princess and Fair Princess were both ex-Cunard, and the former Sitmar Fairsky became Princesss Sky Princess, the first of the three new Sitmar ships came into the Princess brand in 1989 as the Star Princess, the largest British exclusively cruising ship. Two 70,000 grt cruise ships entered service in 1990 as the Crown Princess and Regal Princess, Princess Cruises was involved in litigation with General Electric in 1998 over consequential damages and lost profits resulting from a contract the two parties entered into. General Electric was to provide inspection and repair services upon the SS Sky Princess, upon noticing surface rust on the turbine rotor, the vessel was brought ashore for cleaning and balancing, but good metal was unintentionally removed. This destabilized the rotor, forcing Princess Cruises to cancel two 10-day cruises while additional work was performed, Princess originally prevailed, being awarded nearly $4.6 million. On appeal, however, the judgement was reversed in favor of General Electric, on October 23,2000, the Peninsular & Oriental Steam Navigation Company spun-off its passenger division to form an independent company, P&O Princess Cruises. The company subsequently merged with Carnival Corporation on April 17,2003, as a result of the merger, Carnival Corporation and P&O Princess were integrated to form Carnival Corporation & plc, with a portfolio of eleven cruise ship brands. It is a company, registered in both the United States and the United Kingdom, with the former P&O Princess Cruises being relisted as Carnival plc

Binnacle
–
Its traditional purpose was to hold the ships magnetic compass, mounted in gimbals to keep it level while the ship pitched and rolled. A binnacle may be subdivided into sections and its contents include one or more compasses. Other devices such as a timer for estimating speed may have been stored in the binnacle as well. The construction of many early binnacles used iron nails, which were discovered to cause magnetic deviations in compass readings. As the development of the compass and understanding of magnetism progressed, with the introduction of iron-clad ships the magnetic deviation observed in compasses became more severe. Methods of compensation by arranging iron or magnetic objects near the binnacle were developed, in 1854, a new type of binnacle was patented by John Gray of Liverpool which directly incorporated adjustable correcting magnets on screws or rack and pinions. This was improved again when Lord Kelvin patented in the 1880s another system of compass and these are colloquially known as Kelvins balls in the UK, and navigators balls in the United States. Unlike most display binnacles today, which have the balls painted red and green to represent port and starboard side of the vessel, the Royal Maritime museum at Greenwich, London, has an extensive collection of binnacles in correct colours.

Fife rail
–
A fife rail is a design element of a European-style sailing ship used to belay the ships halyards at the base of a mast. It is one of a dozen or so types of rails often found on such ships, fife rails are typically horizontal strips of either wood or iron and are joined and fitted to the tops of a series of stanchions. The term apparently derives from the location where the ships fifer would sit, a fife rail surrounding a ships mast will contain a series of belaying pins corresponding to the sails on that mast which they belay. Each sail associated with a fife rail will have several corresponding belaying pins set into that rail. Although a fife rail is a kind of pin rail, the pin rail is often used to specifically denote those rails containing belaying pins that are attached to the hull. Unlike these, fife rails are freestanding

Cabin (ship)
–
A cabin or berthing is an enclosed space generally on a ship or an aircraft. A cabin which protrudes above the level of a deck may be referred to as a deckhouse. In sailing ships, the officers and paying passengers would have an individual or shared cabin, the captain or commanding officer would occupy the great cabin that normally spanned width of the stern with large windows. In most modern warships, the officer has a main cabin, the in-port cabin, often adjacent to the ships central control room. Thus, when likely to be called from sleep or attending to administration, the sea cabin is sparsely equipped, containing just a bunk, a desk, and basic toilet facilities. The in-port cabin is more lavishly furnished, with separate bedroom and combination sitting room/office, for ships intended to act as flagships, like the aircraft carrier the USS Lexington, the admiral also has a sea cabin and an in-port cabin, in addition to the captains cabins. Admiral Fletchers sea cabin in the USS Yorktown in World War II had a bed, a chair, a table. Officers will normally have their own cabins, which double as their offices, some senior petty officers may have cabins for similar reasons. In ships carrying passengers, they are accommodated in cabins. First class cabins were referred to as staterooms, and today many cruise lines now prefer to refer to passenger cabins as staterooms or suites. In cruise ship terms, a crawl is an event where passengers tour the cabins of fellow passengers. A cruise ship may also offer a cabin crawl of cabins or suites which did not sell for a particular sailing, the purpose of a cabin crawl is to give passengers an idea of the space and layout of various cabin options for their next cruise. Cabin crawls are normally organized prior to a cruise, through cruise-fan websites, inside spacecraft, the cabins are required to fully supply food and oxygen for their crew. On missions lasting a year or longer, the cabins have to be self-sustaining, i. e. replenish their own water, the space cabin for any long-range manned mission is expected to be reasonably spacious, with approximately 28 cubic metres allotted to each occupant. In addition, cabins have life support systems that should have the capability to meet a variety of conditions, including cabin fires, depressurization. Frequently, these conditions occur so quickly that automatic control systems offer the possibility for recovery. In the late 1960s, several experimental ground facilities were developed to evaluate regenerative life support systems for manned space flight

Vasa (ship)
–
Vasa is a Swedish warship built between 1626 and 1628. The ship foundered after sailing about 1,300 m into her voyage on 10 August 1628. Salvaged with a largely intact hull in 1961, it was housed in a museum called Wasavarvet until 1988. The ship is one of Swedens most popular tourist attractions and has seen by over 35 million visitors since 1961. The ship was built on the orders of the King of Sweden Gustavus Adolphus as part of the expansion he initiated in a war with Poland-Lithuania. She was constructed at the yard in Stockholm under a contract with private entrepreneurs in 1626–1627. Richly decorated as a symbol of the ambitions for Sweden and himself. However, Vasa was dangerously unstable and top-heavy with too much weight in the structure of the hull. Despite this lack of stability she was ordered to sea and foundered only a few minutes after encountering a wind stronger than a breeze, the order to sail was the result of a combination of factors. At the same time the kings subordinates lacked the courage to openly discuss the ships problems or to have the maiden voyage postponed. An inquiry was organized by the Swedish Privy Council to find those responsible for the disaster, during the 1961 recovery, thousands of artifacts and the remains of at least 15 people were found in and around the Vasas hull by marine archaeologists. Among the many items found were clothing, weapons, cannons, tools, coins, cutlery, food, drink, the artifacts and the ship herself have provided scholars with invaluable insights into details of naval warfare, shipbuilding techniques and everyday life in early 17th-century Sweden. During the 17th century, Sweden went from being a populated, poor. Between 1611 and 1718 it was the dominant power in the Baltic, Gustavus Adolphus has been considered one of the most successful Swedish kings in terms of success in warfare. When Vasa was built, he had been in power for more than a decade, Sweden was embroiled in a war with Poland-Lithuania, and looked apprehensively at the development of the Thirty Years War in present-day Germany. The war had been raging since 1618 and from a Protestant perspective it was not successful, the kings plans for a Polish campaign and for securing Swedens interests required a strong naval presence in the Baltic. The navy suffered several setbacks during the 1620s. In 1625, a squadron cruising in the Bay of Riga was caught in a storm, in the Battle of Oliwa in 1627, a Swedish squadron was outmaneuvered and defeated by a Polish force and two large ships were lost

Stem (ship)
–
The stem is the most forward part of a boat or ships bow and is an extension of the keel itself. It is often found on boats or ships, but not exclusively. The stem is the curved edge stretching from the keel below and it is part of the physical structure of a wooden boat or ship that gives it strength at the critical section of the structure, bringing together the port and starboard side planks of the hull. There are two styles of stems, plumb and raked, when the stem comes up from the water, if it is perpendicular to the waterline it is plumb. If it is inclined at an angle to the waterline it is raked, because the stem is very sturdy, the top end of it may have something attached, either ornamental or functional in nature. On smaller vessels, this might be a wood carving or cleat. On large wooden ships, figureheads can be attached to the end of the stem.

Stern
–
The stern is the back or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite of the bow, the foremost part of a ship, originally, the term only referred to the aft port section of the ship, but eventually came to refer to the entire back of a vessel. The stern end of a ship is indicated with a navigation light at night. Sterns on European and American wooden sailing ships began with two forms, the square or transom stern and the elliptical, fantail, or merchant stern. This frame is designed to support the beams that make up the stern. In 1817 the British naval architect Sir Robert Seppings first introduced the concept of the round or circular stern, the square stern had been an easy target for enemy cannon, and could not support the weight of heavy stern chase guns. The United States began building the first elliptical stern warship in 1820, USS Brandywine became the first sailing ship to sport such a stern. In naval architecture, the term transom has two meanings, in this sense, a transom stern is the product of the use of a series of transoms, and hence the two terms have blended. But until a new form of stern appeared in the 19th century, the stern was a floating house—and required just as many timbers, walls, windows. The stern frame provided the structure of the transom stern, and was composed of the sternpost, wing transom. If the stern had transoms above the transom, they would no longer be affixed to the sternpost. The first of these might be called a counter transom, next up was the window sill transom, above that, the larger the vessel, the more numerous and wider the transoms required to support its stern. Stern timbers – These timbers are mounted vertically in a series, each timber typically rests or steps on the transom and then stretches out. Those not reaching all the way to the taffrail are called short stern timbers, the two outermost of these timbers, located at the corners of the stern, are called the side-counter timbers or outer stern timbers. The flat surface of any transom stern may begin either at or above the waterline of the vessel. The geometric line which stretches from the transom to the archboard is called the counter. The visual unpopularity of Seppings circular stern was soon rectified by Sir William Symonds, in this revised stern, a set of straight post timbers stretches from the keel diagonally aft and upward. It rests on the top of the sternpost and runs on either side of the rudder post to a point well above the vessels waterline, the finished stern has a continuous curved edge around the outside and is raked aft

Naval
–
A navy or maritime force is a fleet of waterborne military vessels and its associated naval aviation, both sea-based and land-based. It is the branch of an armed forces principally designated for naval and amphibious warfare, namely, lake-borne, riverine, littoral, or ocean-borne combat operations. The strategic offensive role of a navy is projection of force into areas beyond a countrys shores, the strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. In most nations, the naval, as opposed to navy, is interpreted as encompassing all maritime military forces, e. g. navy, marine / marine corps. First attested in English in the early 14th century, the navy came via Old French navie, fleet of ships, from the Latin navigium, a vessel. The word naval came from Latin navalis, pertaining to ship, cf. Greek ναῦς, ship, ναύτης, seaman, the earliest attested form of the word is in the Mycenaean Greek compound word

Crew
–
A crew is a body or a class of people who work at a common activity, generally in a structured or hierarchical organization. A location in which a crew works is called a crewyard or a workyard, the word has nautical resonances, the tasks involved in operating a ship, particularly a sailing ship, providing numerous specialities within a ships crew, often organised with a chain of command. Traditional nautical usage strongly distinguishes officers from crew, though the two groups combined form the ships company, members of a crew are often referred to by the title Crewman. Crew also refers to the sport of rowing, where teams row competitively in racing shells, for a specific sporting usage, see rowing crew. For filmmaking usage, see film crew, for live music usage, see road crew. For analogous entities in research on human judgment and decision-making, see team, for stagecraft usage, see stage crew. For video production usage, see television crew, for the comic strip, see Motleys Crew. For the sports team, see Columbus Crew, for the 2014 video game, see The Crew.

Sponson
–
Sponsons are projections extending from the sides of land vehicles, aircraft or water craft to provide protection, stability, storage locations, mounting points, or equipment housing. On watercraft, a sponson is a projection that extends outward to improve stability while floating, vessels with unstable body shapes or unevenly distributed weight are likely to feature sponsons to help prevent capsizing or other instabilities. On many vessels, these projections from the body of the vessel can be attached and removed quickly and fairly easily. Canoes and kayaks sometimes feature sponson attachments as well for stability in rough waters and these differ from outriggers, which extend a significant distance away from the body of the craft, and are employed on craft designed for open waters. In the mid-1990s, advances in sponson design made sponsons a tool for better handling at high speeds, there are essentially three types of sponsons for watercraft available on the market today, the basic block type, the hooked or winged type, and the paddle or rudder type. The block type is the simplest type, the leading end is usually round or pointed to allow reduce drag. Its main function is to provide lift on the back of the hull. They can also provide better side-to-side stability at speed and reduce porpoising by providing a bit more hull surface at the rear of the craft. Winged or hooked sponsons are the most common type sold today, in addition to added lift during acceleration, better side-to-side stability, and reduced porpoising, they provide improved handling. The outside edge provides grip in turns, allowing you to turn sharper and faster without fear of the back end sliding out and they can also provide a pivot point for the hull in turns. One of the most overlooked benefits of these types of sponsons is that they have allowed riders to lean into turns more, sponsons on a helicopter can also store fuel or landing gear. It can be used for storage as well as a platform for people entering or leaving the vehicle. It may also provide layers of protection and storage space.

Captain's gig
–
The captains gig /ˈɡɪɡ/ is a boat used on naval ships as the captains taxi. In general, during the era of wooden ships, it was smaller and lighter than the longboat and it was usually crewed by four oarsmen, and a coxswain. Generally the oarsmen sat one to a seat, but each only rowed a single oar on alternating sides, the gig was not as sea kindly as the longboat, but was used mostly in harbors. The gigs generally had a high wineglass transom, full skeg, full keel, straight stem, there was in general very little rocker in the keel. The gunwales on many were nearly straight from bow to stern and it appears to be the precursor to the Whitehall Rowboat. Some wooden captains gigs were quite large and were powered by sail, with the coming of metal ships and combustion engines the size of the captains gig increased and the boats could transport more sailors swiftly. Some modern built craft with sails have been named captains gig as well and these boats were typically painted with a white superstructure and gray hull with a red waterline stripe and black hull below the waterline. They would also frequently have the parent ships hull number marked on the port, in early 2008, in an economy move, Captains Gigs were eliminated from all U. S. Navy aircraft carriers. In science fiction, the term is used to refer to a small auxiliary spacecraft. In Star Trek, the craft are referred to as a captains yacht, cornish pilot gig, a larger boat which used to be used to transport pilots out to ships

Boiler
–
A boiler is a closed vessel in which water or other fluid is heated. The fluid does not necessarily boil, the heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. The pressure vessel of a boiler is usually made of steel, stainless steel, especially of the austenitic types, is not used in wetted parts of boilers due to corrosion and stress corrosion cracking. In live steam models, copper or brass is used because it is more easily fabricated in smaller size boilers. For much of the Victorian age of steam, the material used for boilermaking was the highest grade of wrought iron. In the 20th century, design practice instead moved towards the use of steel, which is stronger and cheaper, with welded construction, which is quicker and requires less labour. It should be noted, however, that wrought iron boilers corrode far slower than their steel counterparts. This makes the longevity of older wrought-iron boilers far superior to those of welded steel boilers, cast iron may be used for the heating vessel of domestic water heaters. Although such heaters are usually termed boilers in some countries, their purpose is usually to produce hot water, not steam, the brittleness of cast iron makes it impractical for high-pressure steam boilers. The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, electric steam boilers use resistance- or immersion-type heating elements. Nuclear fission is used as a heat source for generating steam, either directly or, in most cases. Heat recovery steam generators use the heat rejected from other such as gas turbine. 18th century Haycock boilers generally produced and stored large volumes of very low-pressure steam and these could burn wood or most often, coal. Flued boiler with one or two large flues—an early type or forerunner of fire-tube boiler, fire-tube boiler, Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam. This is the type of boiler used in nearly all steam locomotives, the heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point. Fire-tube boilers usually have a low rate of steam production. Fire-tube boilers mostly burn solid fuels, but are adaptable to those of the liquid or gas variety. Water-tube boiler, In this type, tubes filled with water are arranged inside a furnace in a number of possible configurations and this type generally gives high steam production rates, but less storage capacity than the above

Ship's wheel
–
A ships wheel or boats wheel is a device used aboard a water vessel to change that vessels course. Together with the rest of the mechanism, it forms part of the helm. It is connected to a mechanical, electric servo, or hydraulic system which alters the angle of the vessels rudder relative to its hull. A typical ships wheel is composed of eight wooden spokes shaped like balusters. The outer rim is composed of each made up of stacks of three felloes, the facing felloe, the middle felloe, and the after felloe. Because each group of three felloes at one time made up a quarter of the distance around the rim, the outer wooden wheel was sometimes called the quadrant. Each spoke ran through the middle felloe creating a series of handles beyond the wheels rim, the completed ships wheel and associated axle and pedestal might even be taller than the person using it. The steering gear of earlier shipss wheels sometimes consisted of a wheel where each wheel was connected to the other with a wooden spindle that ran through a barrel or drum. The spindle was held up by two pedestals that rested on a platform, often no more than a grate. Movement of the wheels caused the rope to wind in one of two directions and angled the tiller left or right. Having two wheels connected by an axle allowed two people to take the helm in severe weather when one person alone might not have had enough strength to control the ships movements
30.
Watchstanding
–
Watchstanding, or watchkeeping, in nautical terms concerns the division of qualified personnel to operate a ship continuously. On a typical sea-faring vessel, be it naval or merchant, personnel keep watch on the bridge, the generic bridge watchstanders are a lookout and an officer or mate who is responsible for the safe navigation of the ship. Safe navigation means keeping the vessel on course and away from dangers as well as collision avoidance from other shipping, an engineering specialist ensures that running machinery continues to operate within tolerances and depending on the vessel, this can also be accomplished from the bridge. A secondary function of watchkeeping is to respond to emergencies, be it on own ship or involving other ships, a wide variety of types of watches have developed due to need aboard merchant and naval vessels. Examples of other systems include 4 by 6-hour and 7s and 5s when a warship has half its ships company on watch at a time. The watches kept on sailing ships—the square-rigged barques or windjammers of the late 19th century and those members of the crew whose work must be done at all times of the day were assigned to one of two divisions, the Starboard or the Port division. A similar system can also be used with a divided into three, giving each sailor more time off-duty. Names for the three watches—instead of Port and Starboard—vary between ships, Foremast, Mainmast and Mizzen and Red, White and Blue are common, ships bells are a system to indicate the hour by means of bells, used aboard a ship to regulate the sailors duty watches. Unlike civil clock bells, the strikes of the bell do not accord to the number of the hour, instead, there are eight bells, one for each half-hour of a four-hour watch. Bells would be struck every half-hour, and in a pattern of pairs for easier counting, the traditional system is, Watch system United States Naval Institute.

Conn (nautical)
–
The conn, also spelled cun, conne, cond, conde, and cund, is the act of controlling a ships movements while at sea. The following quote summarizes the use of the term, One of the most important principles of ship handling is that there be no ambiguity as to who is controlling the movements of the ship. One person gives orders to the engine, rudder, lines. This person is said to have the conn, within the U. S. Navy, the captain of a vessel typically selects a junior officer to perform the role of conning for him or her. Such an individual has the title of officer of the deck or the officer while on duty. However, the captain can immediately take the conn by simply issuing an order to the helm. On navy ships, neither the ships nor the ships pilot is usually the conning officer, whereas on merchant ships the conning officer may be the captain. The officer of the deck may give the conn to an officer for training purposes, in which case the officer of the deck. It is from this term that the concept of a conning tower, an elevated platform from which a conning officer can view all aspects of a ships movement, is derived. Although the origin of the term is not entirely clear, it appears that conn is a form of conduct

This is a partial glossary of nautical terms, some remain current, while many date from the 17th to 19th centuries. See also Wiktionarys nautical terms, Category, Nautical terms, See the Further reading section for additional words and references. A & AS Alterations and additions to the structure, rigging, abaft Toward the stern, relative to some object. Abaft the beam Further aft than the beam, a bearing of greater than 90 degrees from the bow. That would describe an object lying 22.5 degrees toward the rear of the ship, as measured clockwise from a line from the right side, center, of the ship. An imperative to leave the vessel immediately, usually in the face of some imminent overwhelming danger and it is an order issued by the Master or a delegated person in command. Abeam On the beam, a bearing at right angles to the ships keel. A merchant seaman qualified to perform all duties, or a junior rank in some navies. Aboard On or in a vessel, about To go about is to change the course of a ship by tacking. Ready about, or boutship, is the order to prepare for tacking, above board On or above the deck, in plain view, not hiding anything. Pirates would secret their crews below decks, thereby creating the impression that an encounter with another ship was a casual matter of chance.

Deck (bridge)
–
A bridge deck or road bed is the roadway, or the pedestrian walkway, surface of a bridge, and is one structural element of the superstructure of a bridge. It is not to be confused with any deck of a ship, the deck may be constructed of concrete, steel, open grating, or wood. Sometimes the deck is covered with concrete or other pavement. The concrete deck may be a part of the bridge structure or it may be supported with I-beams or steel girders. When a bridge deck is installed in a truss, it is sometimes called a floor system. A suspended bridge deck will be suspended from the structural elements on a suspension or arch bridge. On some bridges, such as a tied-arch or a cable-stayed, structural engineers have several principal categories of bridge decks, for the purposes of analytic techniques. A beam deck is one where the deck and any supporting structure act together as a single beam, a grid deck uses beams and diaphragms as the supporting structure. The supporting system of a deck is analyzed using a grillage analysis. A slab deck is one where the deck is analyzed as a plate, if the slab has a stiffness that is different in two directions, then the deck is known and analyzed as an orthotropic deck. A beam and slab deck is one where the beams may deflect somewhat independently, a cellular deck is one where a number of thin slabs and webs will enclose cells within the deck. A boxgirder deck is one where the forms the top of the box girder during analysis. In the case of a bridge, when the railway track and ties are supported on load carrying elements of the superstructure. When the track rests upon ballast, which is carried by the superstructure of the bridge. A third type of support is direct fixation, where ties are not used.

Bridge (nautical)
–
The bridge of a ship is the room or platform from which the ship can be commanded. When a ship is underway the bridge is manned by an OOW aided usually by an AB acting as lookout. During critical maneuvers the captain will be on the bridge supported, perhaps, by an OOW as a set of hands. Wheelhouses are the small enclosed parts of a bridge that historically held the ships wheel, today, ships bridges do not have a separate wheelhouse, the term wheelhouse or pilothouse is used nowadays to refer to the smaller bridges of small vessels, such as tugs. Traditionally, sailing ships were commanded from the quarterdeck, aft of the mainmast, with the arrival of paddle steamers, engineers required a platform from which they could inspect the paddle wheels and where the captains view would not be obstructed by the paddle houses. A raised walkway, literally a bridge, connecting the houses was therefore provided. When the screw propeller superseded the paddle wheel, the bridge was retained, helm orders would be passed to an enclosed wheel house, where the coxswain or helmsman operated the ships wheel. Engine commands would be relayed to the engineer in the room by an engine order telegraph that displayed the captains orders on a dial. The engineer would ensure that the combination of steam pressure. Iron, and later steel, ships also required a compass platform and this was usually a tower, where a magnetic compass could be sited far away as possible from the ferrous interference of the hulk of the ship. Depending upon the design and layout of a ship, all of these terms can be variously interchangeable, larger ships, particularly warships, often had a number of different bridges. A navigation bridge would be used for the conning of the ship. A separate admirals bridge could be provided in flagships, where the admiral could exercise control over his fleet without interfering with the Captains tactical command of the vessel. In older warships, an armored conning tower was often provided. Modern advances in remote control equipment have seen progressive transfer of the control of the ship to the bridge. The wheel and throttles can be operated directly from the bridge, aboard modern warships it is common that actual commanding is carried out on the bridge while weapon systems are controlled from a room usually deep inside the vessel. This also enables a redundant setup in which the vessel is able to fight in case one of the command instances has been hit or destroyed. On a commercial vessel, the bridge will contain the equipment necessary to navigate a vessel on passage

Flight deck
–
The flight deck of an aircraft carrier is the surface from which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the official U. S. Navy term for these vessels is air-capable ships. The first flight decks were inclined wooden ramps built over the forecastle of warships, eugene Ely made the first fixed-wing aircraft take-off from a warship from USS Birmingham on 14 November 1910. Ely told a reporter, It was easy enough, I think the trick could be successfully turned nine times out of ten. On 9 May 1912, Commander Charles Samson became the first man to take off from a ship which was underway when he flew his Short S.27 off of HMS Hibernia, which was steaming at 10.5 kn. Because the take-off speed of aircraft was so low, it was possible for an aircraft to make a very short take off when the launching ship was steaming into the wind. The landing arrangements on Furious were highly unsatisfactory, in order to land, aircraft had to manoeuvre around the superstructure. Furious was therefore returned to dockyard hands to have a 300 ft deck added aft for landing, the central superstructure remained, however, and turbulence caused by it badly affected the landing deck. Because of her flight deck, Argus had no fixed conning tower. Rather, exhaust gases were trunked down the side of the ship, the lack of a command position and funnel was unsatisfactory, and Argus was used to experiment with various ideas to remedy the solution. A photograph in 1917 shows her with a canvas mock-up of an island superstructure. This became the aircraft carrier arrangement and was used in the next British carriers, Hermes. Being large and fast they were suited to this role. Because the military effectiveness of aircraft carriers was then unknown, early ships were equipped with cruiser-calibre guns to aid in their defense if surprised by enemy warships. In ships of this configuration, the deck was the strength deck and an integral part of the hull. Such ships were still being built into the late 1940s, classic examples being the U. S. Navys Essex, however, in 1936, the Royal Navy began construction of the Illustrious class. In these ships, the deck was the strength deck, an integral part of the hull. The flight deck as the deck was adopted for later construction

Forecastle
–
Forecastle refers to the upper deck of a sailing ship forward of the foremast, or the forward part of a ship with the sailors living quarters. Related to the meaning is the phrase before the mast which denotes anything related to ordinary sailors. The syncope of the word, focsle or focsle, is common among nautical terms, the positioning of the apostrophes represents silent letters, thus focsle. In medieval shipbuilding, a ship of war was usually equipped with a tall and it served as a platform for archers to shoot down on enemy ships, or as a defensive stronghold if the ship were boarded. A similar but usually much larger structure, called the aftcastle, was at the aft end of the ship, having such tall upper works on the ship was detrimental to sailing performance. Sailors stationed on the forecastle, or forecastle men, were responsible for handling the headsails, in the Royal Navy of the 17th and 18th centuries, these roles were reserved for older seamen who lacked the agility to go aloft or take other more strenuous duties aboard. By the end of the 19th century, raised forecastle had become a feature on warships again, in an attempt to keep forward gun positions from getting unacceptably wet on heavy seas. In addition the forecastle may provide additional crews quarters as in the past, a disadvantage of such a design is the structural weakness at the forecastle break relative to a flush deck structure.

Freeboard (nautical)
–
In sailing and boating, a vessels freeboard is the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. In commercial vessels, the latter criterion measured relative to the load line. In yachts, a low freeboard is often found on racing boats, for drag/weight reduction, a higher freeboard will give more room in the cabin, but will increase weight and drag, compromising speed. A higher freeboard also helps weather waves and reduce the likelihood of being washed over by water waves on the weather deck. A low-freeboard boat is susceptible to taking in water in rough seas, freighter ships and warships use high freeboard designs to increase internal volume which also allows them to satisfy IMO damage stability regulations due to increased reserved buoyancy.

Gun deck
–
The term gun deck used to refer to a deck aboard a ship that was primarily used for the mounting of cannon to be fired in broadsides. However, on smaller vessels such as frigates and unrated vessels. The completely covered level under the deck was, however. On board marine seismic survey vessels, the lowest deck on the ship is referred to as the gun deck. This deck carries the seismic source arrays, consisting of air guns arranged in clusters, the term gun deck is also navy slang for fabricating or falsifying something. This term is now used to indicate the falsification of documentation in order to avoid doing the work or make present conditions seem otherwise acceptable, glossary of nautical terms Son of a gun

Hangar
–
A hangar is a closed building structure to hold aircraft, spacecraft or tanks in protective storage. Most hangars are built of metal, but other such as wood. The word hangar comes from Middle French hanghart, of Germanic origin, from Frankish *haimgard, from *haim, hangars are used for protection from the weather, direct sunlight, maintenance, repair, manufacture, assembly and storage of aircraft on airfields, aircraft carriers and ships. The Wright brothers stored and repaired their aircraft in a wooden hangar constructed in 1902 at Kill Devil Hills in North Carolina for their glider, after completing design and construction of the Wright Flyer in Ohio, the brothers returned to Kill Devil Hill only to find their hangar damaged. They repaired the structure and constructed a new workshop while they waited for the Flyer to be shipped, bleriot was in a race to be the first man to cross the English Channel in a heavier-than-air aircraft and set up his headquarters in the unused shed. In Britain, the earliest aircraft hangars were known as aeroplane sheds and these were built in 1910 for the Bristol School of Flying and are now Grade II* Listed buildings. Examples of the latter survive at Farnborough, Filton and Montrose airfields, during World War I, other standard designs included the RFC General Service Flight Shed and the Admiralty F-Type of 1916, the General Service Shed and the Handley Page aeroplane shed. Airship hangars or airship sheds are generally larger than conventional aircraft hangars, most early airships used hydrogen gas to provide them with sufficient buoyancy for flight, so their hangars had to provide protection from stray sparks to keep the gas from exploding. Hangars that held several airships were at risk from chain-reaction explosions, for this reason, most hangars for hydrogen-based airships were built to house only one or two such craft. During the Golden Age of airship travel from 1900, mooring masts and sheds were constructed to build, steel rigid airship hangars are some of the largest in the world. Hangar 1, Lakehurst, is located at Naval Air Engineering Station Lakehurst, the structure was completed in 1921 and is typical of airship hangar designs of World War I. The site is best known for the Hindenburg disaster, when on May 6,1937, Hangar No.1 at Lakehurst was used to build and store the American USS Shenandoah. The hangar also provided service and storage for the airships USS Los Angeles, Akron, Macon, as well as the Graf Zeppelin and the Hindenburg. The largest hangars ever built include the Goodyear Airdock measuring 1, 175x325x211 feet, the Goodyear Airdock, is in Akron, Ohio and the structure was completed on November 25,1929. The Airdock was used for the construction of the USS Akron and her sister ship, Hangar One at Moffett Federal Field, is located in Mountain View, California. The structure was completed in 1931, the US Navy established more airship operations during WWII. As part of this ten lighter-than-air bases across the United States were built as part of the defense plan. Hangars at these bases are some of the worlds largest freestanding timber structures, an alternative to the fixed hangar is a portable shelter that can be used for aircraft storage and maintenance

Mast (sailing)
–
The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sail, spars, and derricks, and giving necessary height to a light, look-out position, signal yard, control position. Large ships have several masts, with the size and configuration depending on the style of ship, nearly all sailing masts are guyed. Until the mid-19th century all vessels masts were made of wood formed from a single or several pieces of timber which typically consisted of the trunk of a conifer tree. From the 16th century, vessels were built of a size requiring masts taller and thicker than could be made from single tree trunks. On these larger vessels, to achieve the height, the masts were built from up to four sections, known in order of rising height above the decks as the lower, top, topgallant. Giving the lower sections sufficient thickness necessitated building them up separate pieces of wood. Such a section was known as a made mast, as opposed to sections formed from pieces of timber. Jigger-mast, typically, where it is the shortest, the aftmost mast on vessels with more than three masts. On a two-masted vessel with the main-mast forward and a smaller second mast, such as a ketch, or particularly a yawl. Although two-masted schooners may be provided with masts of identical size, the aftmost is still referred to as the main-mast, schooners have been built with up to seven masts in all, with several six-masted examples. On square-rigged vessels, each mast carries several horizontal yards from which the sails are rigged. A two-masted merchant vessel with a sizable foresail rigged on a slightly inclined foremast is depicted in an Etruscan tomb painting from 475–450 BC. While most of the ancient evidence is iconographic, the existence of foremasts can also be deduced archaeologically from slots in foremast-feets located too close to the prow for a mainsail. Artemon, along with mainsail and topsail, developed into the rig of seagoing vessels in imperial times. The imperial grain freighters travelling the routes between Alexandria and Rome also included three-masted vessels, a mosaic in Ostia depicts a freighter with a three-masted rig entering Romes harbour. Special craft could carry many more masts, Theophrastus records how the Romans imported Corsican timber by way of a raft propelled by as many as fifty masts. Throughout antiquity, both foresail and mizzen remained secondary in terms of size, although large enough to require full running rigging

Helicopter deck
–
A helicopter deck is a helicopter pad on the deck of a ship, usually located on the stern and always clear of obstacles that would prove hazardous to a helicopter landing. In the United States Navy, it is commonly and properly referred to as the flight deck, shipboard landing for some helicopters is assisted though use of a haul-down device that involves attachment of a cable to a probe on the bottom of the aircraft prior to landing. This device was pioneered by the Royal Canadian Navy and was called Beartrap, the U. S. Navy implementation of this device, based on Beartrap, is called the RAST system and is an integral part of the LAMPS Mk III weapons system. A secondary purpose of the device is to equalize electrostatic potential between the helicopter and ship. This was depicted in the 1990 film The Hunt for Red October, Ryan is lowered to the submarine, but brushes the officer charged with trying to hook him who receives a minor injury. Coaxial rotor helicopters in flight are highly resistant to side-winds, which makes suitable for shipboard use. The Largest Marine Heli decks will accommodate the Boeing CH-47 Chinook, which requires a D value of 30 metres, more typical for vessels would be decks that will accommodate the Sikorsky S92 with a D value of 21 metres and 11.9 tons.
