Sail plan
–
A sail plan is a set of drawings, usually prepared by a naval architect which shows the various combinations of sail proposed for a sailing ship. Alternatively, as a term of art, it refers to the way such vessels are rigged as discussed below, the combinations shown in a sail plan almost always include three configurations, A light air sail plan. Over most of the Earth, most of the time, the force is Force 1 or less. Thus a sail plan should include a set of huge, lightweight sails that will keep the ship underway in light breezes and this is the set of sails that are changed rapidly in variable conditions. They are much stronger than the light air sails, but still lightweight, an economical sail in this set will include several sets of reefing ties, so the area of the sail can be reduced in a stronger wind. This is the set of small, very rugged sails flown in a gale, to keep the vessel under way. In all sail plans, the attempts to balance the force of the sails against the drag of the underwater keel in such a way that the vessel naturally points into the wind. In this way, if control is lost, the vessel will avoid broaching, broaching always causes uncomfortable motion, and in a storm, the breaking waves can destroy a lightly built boat. The architect also tries to balance the force on each sail plan against a range of loads. The calculation assures that the sail will not knock the vessel sideways with its mast in the water, capsizing, fore-and-aft rig features flat sails that run fore and aft. These types of sails are the easiest to manage, because they often do not need to be relaid when the ship changes course, Bermuda rig is a type of fore-and-aft rig with a triangular mainsail. Gaff rig features fore-and-aft sails shaped like a triangle minus its point, the top of the sail tends to twist away from the wind reducing its efficiency when close-hauled. However, due to the gaff on the top edge of the sail the centre of effort is typically lower, square rig features sails set square to the mast from a yard, a spar running transversely in relation to the hull. In ships built using designs of the square rig, sailors would have to climb the rigging. In a modern square rigged design the crew can furl and unfurl sails by remote control from the deck, lateen rig features a triangular sail set on a long yard, mounted at an angle on the mast and running in a fore-and-aft direction. This is one of the lowest drag sails, each form of rig requires its own type of sails. Among them are, A staysail is a piece of cloth that has one or two attached to a stay, that is, one of the ropes or wires that helps hold the mast in place. A staysail was classically attached to the stay with wooden or steel hoops, sailors would test the hoops by climbing on them

Bermuda rig
–
A Bermuda rig, Bermudian rig, or Marconi rig is a configuration of mast and rigging for a type of sailboat and is the typical configuration for most modern sailboats. Originally developed for smaller Bermudian vessels, and ultimately adapted to the larger, ocean-going Bermuda sloop, the Bermuda rigging has largely replaced the older gaff rigged fore-and-aft sails, except notably on schooners. The traditional design as developed in Bermuda features very tall, raked masts, a long bowsprit, in some configurations such as the Bermuda Fitted Dinghy vast areas of sail are achieved with this rig. Elsewhere, however, the design has omitted the bowsprit, and has become less extreme. A Bermuda rigged sloop with exactly one jib is known as a Bermuda sloop, a Bermuda sloop may also be a more specific type of vessel such as a small sailing ships traditional in Bermuda which may or may not be Bermuda rigged. The foot of a Bermuda sail may be attached to the boom along its length and this modern variation of a Bermuda mainsail is known as a loose-footed main. In some early Bermudian vessels, the mainsails were attached only to the mast and deck and this is the case on two of the three masts of the newly built Spirit of Bermuda, a replica of an 1830s British Royal Navy sloop-of-war. Additional sails were often mounted on traditional Bermudian craft, when running down wind, which included a spinnaker, with a spinnaker boom. The main controls on a Bermuda sail are, The halyard used to raise the head, the outhaul used to tension the foot by hauling the clew towards the end of the boom. The sheet used to haul the boom down and towards the center of the boat, the vang or kicking strap which runs between a point partway along the boom and the base of the mast, and is used to haul the boom down when on a run. The Bermuda rig developed from leg-of-mutton sails in Bermuda during the course of the 17th and 18th cnturies, the design was very useful on the gusty Bermudian waters for the boats that were the mainstay of transport around the archipelago into the 20th century. As Bermuda turned to an economy, after the dissolution of the Somers Isles Company in 1684, the rig was adapted to larger, ocean-going ships. The development of the rig is thought to have begun with fore-and-aft rigged boats built by a Dutch-born Bermudian in the 17th Century, the Dutch were influenced by Moorish lateen rigs introduced during Spains rule of their country. The Dutch eventually modified the design by omitting the masts, with the arms of the lateens being stepped in thwarts. By this process, the yards became raked masts, lateen sails mounted this way were known as leg-of-mutton sails in English. The Dutch called a vessel rigged in this manner a bezaanjacht, a bezaan jacht is visible in a painting of King Charles II arriving in Rotterdam in 1660. After sailing on such a vessel, Charles was so impressed that his successor, the Prince of Orange presented him with a copy of his own. The rig had been introduced to Bermuda some decades before this, Ships with somewhat similar rigs were in fact recorded in Holland during the 17th century

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

Bow (ship)
–
The bow /ˈbaʊ/ is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. Both of the fore and forward mean towards the bow. The other end of the boat is the stern, from Middle Dutch boech or Old Norse bógr. The bow is designed to reduce the resistance of the cutting through water. On slower ships like tankers, a bow shape is used to maximise the volume of the ship for a given length. A wet bow results from seawater washing over the top of the hull, a raked stem can help to reduce the wetness of the bow. Aside from making the deck slippery, water can corrode the metal of the ship, if the temperature is low enough this water can also freeze on the deck, rails, turrets, and other exposed surfaces, increasing the topside weight. The bow may be reinforced to serve as an ice-breaker, one example being the bow of container-ship Sea Witch whose reinforcement assisted its destruction of another ship in a 1973 collision, the forward part of the bow, usually on the ships centreline, is called the stem. Traditionally, the stem was a timber or metal bar into which side planks or plates were joined. ISBN 0-7566-0944-5 Steward, Robert, Boatbuilding Manual, 3rd ed.

Centreboard
–
A centreboard or centerboard is a retractable keel which pivots out of a slot in the hull of a sailboat, known as a centreboard trunk or centerboard case. A centreboard which consists of just a metal plate is called a centerplate. A daggerboard is similar but slides vertically rather than pivoting, the analog in a scow is a bilgeboard, these are fitted in pairs and used one at a time. Lt. John Schank was an officer of the British Royal Navy and is credited with the invention of the centerboard, Schank, however, gave credit for the idea to British Brigadier General Earl Percy. A centreboard is used to lift to counter the lateral force from the sails. This is required for sailboats to move in directions other than downwind, the more a yacht heels the more asymmetric its hull shape becomes. The centerboard, daggerboard or bilgeboard can be used as a platform upon which to stand, providing increased leverage. The efficiency of a centreboard improves with increasing aspect ratio, a long narrow centreboard produces less drag than a short, wide one for a given amount of lift, resulting in a faster boat that can point closer into the wind. A fore and aft, pivoting centreboard can also be used to move the centre of lateral resistance aft to match a change in sail plan, such as furling or dropping the jib. A retracting centreboard is more complex than a keel. Other types feature a casing under the boat, which does not take up space, for this reason, it is not uncommon to find boats with a combination of shallow keel and centreboard. The keel provides the housing for the centreboard, moving it out of the hull, the centreboard can then be lowered in deeper waters to increase the amount of lift. Ballast is usually provided in the keel, keeping the lighter and easier to handle. Centreboards are often ballasted in keelboats, ballasted centreboards are generally not locked in place when lowered, the mass of the ballast keeps them down. The mass of a ballasted foil means that a system of pulleys may be required to allow the sailor to lift the foil, and a method of latching the board in the upward position is needed. A centreboard differs from a ballast keel in that centreboards do not contribute to the stability of the vessel, in small sailing dinghies it is rare to find a ballasted centreboard. On larger sailing vessels, a design is sometimes incorporated to enable navigation into shallower water than a fixed keel would allow. In these situations the appendage is generally referred to as a keel or a swing keel

Keel
–
On boats and ships, keel can refer to either of two parts, a structural element that sometimes resembles a fin and protrudes below a boat along the central line, or a hydrodynamic element. As the laying down of the keel is the step in the construction of a ship, in British. Only the ships launching is considered significant in its creation. The word can also be used as a synecdoche to refer to a complete boat, a structural keel is the bottom-most structural member around which the hull of a ship is built. The keel runs along the centerline of the ship, from the bow to the stern. The keel is often the first part of a hull to be constructed. The most common type of keel is the plate keel. A form of keel found on smaller vessels is the bar keel, which may be fitted in trawlers, tugs, and smaller ferries. Where grounding is possible, this type of keel is suitable with its massive scantlings, if a double bottom is fitted, the keel is almost inevitably of the flat plate type, bar keels often being associated with open floors, where the plate keel may also be fitted. Duct keels are provided in the bottom of some vessels and these run from the forward engine room bulkhead to the collision bulkhead and are utilized to carry the double bottom piping. The piping is then accessible when cargo is loaded, the keel surface on the bottom of the hull gives the ship greater directional control and stability. In non-sailing hulls, the helps the hull to move forward. In traditional boat building, this is provided by the structural keel, in modern construction, the bar keel or flat-plate keel performs the same function. There are many types of fixed keels, including full keels, long keels, fin keels, winged keels, bulb keels, the rudimentary purpose of the keel is to convert the sideways motion of the wind when it is abeam into forward motion. A secondary purpose of the keel is to provide ballast, keels are different from centreboards and other types of foils in that keels are made of heavy materials to provide ballast to stabilize the boat. Keels may be fixed, or non-movable, or they may retract to allow sailing in shallower waters, retracting keels may pivot or slide upwards to retract, and are usually retracted with a winch due to the weight of the ballast. Since the keel provides far more stability when lowered than when retracted, types of non-fixed keels include swing keels and canting keels. Canting keels can be found on racing yachts, such as competing in the Volvo Ocean Race

Gaff rig
–
Gaff rig is a sailing rig in which the sail is four-cornered, fore-and-aft rigged, controlled at its peak and, usually, its entire head by a spar called the gaff. Because of the size and shape of the sail, a gaff rig will have running backstays rather than permanent backstays, the gaff enables a fore and aft sail to be four sided, rather than triangular. A gaff rig typically carries 25 percent more sail than an equivalent bermudian rig for a hull design. A sail hoisted from a gaff is called a gaff-rigged sail, gaff rig remains the most popular fore-aft rig for schooner and barquentine mainsails and other course sails, and spanker sails on a square rigged vessel are always gaff rigged. The gaff is hoisted by two halyards, The throat halyard hoists the throat of the sail at the end of the gaff and bears the main weight of the sail. The peak halyard lifts aft end of the gaff and bears the leech tension. Small craft attach the peak halyard to the gaff with a span with eyes at both ends looped around the gaff and held in place with small wooden chocks, larger craft have more than one span. Peak halyards pull upwards, approaching the gaff at right angles, additionally, a gaff vang may be fitted. It is an attached to the end of the gaff which prevents the gaff from sagging downwind. Gaff vangs are difficult to rig on the aft-most sail, so are only found on schooners or ketches. A triangular fore-and-aft sail called a jib-headed topsail may be carried between the gaff and the mast. Gunter-rigged boats are similar, smaller vessels on which a spar popularly but incorrectly called the gaff is raised until it is vertical, parallel to the mast. Topsails are never carried on gunter rigs, the Spritsail is another rig with a four-sided fore-aft sail. Unlike the gaff rig where the head hangs from a spar along its edge, the forward end of the sprit is attached to the mast but bisects the face of the sail, with the after end of the sprit attaching to the peak and/or the clew of the sail. For a given sail area a gaff rig has a shorter mast than a bermudian rig, because of its low aspect ratio, the gaff rig is less prone to stalling if oversheeted than something taller and narrower. Whilst reaching, the CE being set back, will encourage a small craft to bear up into the wind. The boat builder can compensate for this at design stage, e. g. by shifting the keel slightly aft, the gaff-cutter is in fact a very popular sailplan for small craft. The helmsman can reduce weather helm significantly, simply by sheeting out the mainsail, sheeting out may appear to create an inefficient belly in the sail, but it is often a pragmatic alternative to having a heavy helm

Beam (nautical)
–
The beam of a ship is its width at the widest point as measured at the ships nominal waterline. The beam is a bearing projected at right-angles from the fore and aft line, Beam may also be used to define the maximum width of a ships hull, or maximum width plus superstructure overhangs. Typical length-to-beam ratios for small sailboats are from 2,1 to 5,1, large ships have widely varying beam ratios, some as large as 20,1. Rowing shells designed for racing may have length to beam ratios as high as 30,1. The beam of many vessels can be calculated using the following formula. Some examples, For a standard 27 ft yacht, the root of 27 is 3,3 squared is 9 plus 1 =10. The beam of many 27 ft monohulls is 10 ft, for a Volvo Open 70 yacht,70.5 to the power of 2/3 =17 plus 1 =18. The beam is often around 18 ft, for a 741 ft long ship, the cube root is 9, and 9 squared is 81, plus 1. The beam will usually be around 82 ft, e. g. Seawaymax, as catamarans have more than one hull, there is a different beam calculation for this kind of vessel. BOC stands for Beam On Centerline and this term in typically used in conjunction with LOA. The ratio of LOA/BOC is used to estimate the stability of multihull vessels, the lower the ratio the greater the boats stability. The BOC for vessels is measured as follows, For a catamaran, carlin – similar to a beam, except running in a fore and aft direction. Keever, John M.

Waterline length
–
The waterline length is the length of a ship or boat at the point where it sits in the water. It excludes the length of the boat, such as features that are out of the water. Most boats rise outwards at the bow and stern, so a boat may be quite a bit longer than its waterline length. In a ship with raked stems, naturally the waterline length changes as the draft of the ship changes. Length at the waterline is often abbreviated as lwl, w/l and this measure is essential in determining a lot of properties of a vessel, such as how much water it displaces, where the bow and stern waves are, hull speed, amount of bottom-paint needed, etc. In sailing boats, longer waterline length will usually enable a greater speed, because it allows greater sail area. Higher beam and draft causes higher resistance against the water and this maximum speed, also known as theoretical hull speed, can be calculated using the formula x 1.34. Length overall Length between perpendiculars Hayler, William B, keever, John M. American Merchant Seamans Manual. Turpin, Edward A. McEwen, William A

Beetle Cat
–
A Beetle Cat is a 12-foot-4-inch catboat first built in 1920 in New Bedford, Massachusetts by members of the Beetle family. Beetle, Inc. now in Wareham, Massachusetts, is the builder of Beetle Cat boats. A new Beetle 14 catboat, with seating, accommodates four adults and has 80% more cockpit interior space. Designed by Bill Sauerbrey in 2006/2007, it underwent a sea trial in late April 2007, the Beetle Cat is named after its designer, John Beetle, who drew the lines for the pleasure boat in 1920. The 12-foot-long, gaff-rigged boats design was based on the 20-to-30-foot catboats used for shallow water fishing along Cape Cod, with interest in the Beetle Cat and the demise of the whaling industry, the family shifted production to the Beetle Cat boat. During World War II, all production of the Beetle Cat was suspended, among the crew was master builder Leo Telesmanick. In 1993, the Beetle Cat division was sold to Charlie York, in October 2003, William L. Womack became the new owner of Beetle Inc. with Charlie York remaining the Master Builder. Womack re-located the operation to Wareham MA, Beetle Cat Inc. also builds other custom wooden sail and power yachts. In 2005–06, Womack accepted a commission to build a scaled-up 28-foot version of a Beetle Cat, hanley Catboat, the yacht Kathleen was featured in the November/December 2006 issue of WoodenBoat magazine. The craft is a wooden boat used for racing purposes. The small cedar-hull and fir-spar boat has a sail of approximately 100 square feet, a new one costs nearly $17,000, while older ones come on the market from time to time. Beetles are built as planks of Atlantic white cedar over white oak frames, the seams are caulked with cotton. Beetle Cats in Massachusetts are often compared to the Herreshoff/Haven 12. 5s, both vessels share old-school style, boat handling, and aesthetic qualities and both attract similar classic wood-boat enthusiasts. Both craft have been included in coffee table books about classic wooden boats. Beetle, Inc. introduced a Bill Sauerbrey designed Beetle 14 in 2007, the Beetle 14-foot catboat is cedar-planked over white oak frames, with a canvas deck and oak coamings similar in style to the Beetle Cat. Two feet longer in length, the cockpit seats four adults, the interior on the first boat had a natural cockpit at the request of the owner, with painted or varnished seats. The developer made the custom stem head fitting, mast band, the spars were built of solid Douglas fir and finished off with bronze hardware and blocks. The Beetle 14 boat carries 163 sq ft. of sail, proportionate to the Beetle Cats rig, however, a topping lift is standard, as well as more purchase on the peak halyard and mainsheet

Nonsuch (sailboat)
–
The Nonsuch line of catboats is a series of popular cruising sailboats built between 1978 and the mid-1990s by Hinterhoeller Yachts in St. Catharines, Ontario. They were popular in North America, with over 950 ships built, the Nonsuch class was named after the Nonsuch that was the first trading vessel of Hudsons Bay Company, which in turn was named after the Baroness Nonsuch, a mistress of King Charles II of England. Ellis designed a Ljungstrom-type rig modified with a boom, on a 30-foot modern hull with a plumb bow, fin keel. A beam of nearly 12 feet and cambered house-top created an interior with accommodation equal to a standard yacht several feet longer. George Hinterhoeller, after some initial reservations about the design, agreed to build the boats, additional models were created in 22,26,33,36 and 40 foot lengths, with the 26 and 30 both available in Classic and Ultra configurations. The original boats were built with an unstayed, two-piece aluminum mast, in later years, under new ownership, the factory produced new versions of 3 of its models, all with shoal draft keels one-piece carbon fiber masts. By the time Hinterhoeller closed its doors in January 1996, a total of 975 Nonsuch boats had been built, the Nonsuch series of boats are generally considered to be very sturdily built boats. As of January,2007, Wiggers Custom Yachts, a Canadian yacht builder located in Bowmanville, operating under licensing agreements with designer, Wiggers states they will build boats to order. As of October 2009, five Nonsuch 33s have been delivered, the Nonsuch starts its own class, usually 12-15 boats, in the Spring and Fall Off Soundings race series. Rendezvous are held two years, alternating between Canada and the United States. The 2012 Rendezvous was held in Greenport, New York

Inland cat
–
Inland Cat is a class of one- or two-man sailboats, almost exclusively found on Lake George, Indiana/Michigan. The craft is approximately 14.5 feet in length, with a 4.5 foot beam, the sail is a Marconi rig, with the mast far forward on the hull, as is the norm for a cat boat. The boat has a retractable galvanized steel centerboard, and an aluminum rudder similar in shape to New England-style cat boats. The design was created by Norm Bell and John Larimore in the mid-1950s and used then-current polyester resin, the boat was perhaps over-engineered, and is quite robustly built. Many examples, including hull #2 continue to race every Saturday during the summer months, there were 250+ Inland Cats built by Bell/Larimore and a nearby boatbuilder in the 1950s thru early 1970s. The only concentration of boats is on Lake George proper, which has a few dozen surviving craft, of these, 20+ come out to race in the Gold and Silver fleets each week during the Summer. Due to its construction and wide beam, the Inland Cat is very stable in heavy air. The Class has a PHRF rating of 107 and it is not uncommon on balmy summer days to see the entire fleet bobbing in light air, tossed about by Jet Ski and other boat wakes. The Inland Cat logo is a silhouette of a cats head with a red I centered over it

Catamaran
–
A catamaran is a multi-hulled watercraft featuring two parallel hulls of equal size. It is a craft, deriving its stability from its wide beam. Being ballast-free and therefore lighter than a monohull, catamarans often have a draft than comparably-sized monohulls. The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less power from either sails or motors. The catamarans wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes, Catamarans range in size from small to large. The structure connecting a catamarans two hulls ranges from a simple frame strung with webbing to support the crew to a bridging superstructure incorporating extensive cabin and/or cargo space, Catamarans from Polynesia and Maritime Southeast Asia became the inspiration for modern catamarans. Catamaran-type vessels were first developed as early as 1500 BCE by the Polynesian peoples and these early examples were likely related to outrigger canoes and consisted of two canoes bound together with a wooden frame, sometimes accompanied by a sail. Despite their simplicity they were effective, allowing seafaring Polynesians to voyage to distant Pacific islands. Catamarans were seldom constructed in the West before the 19th century, the word catamaran is derived from the Tamil word, kattumaram, which means logs bound together. The 17th-century English adventurer and privateer William Dampier encountered the Tamil people of southeastern India during his first circumnavigation of the globe and he was the first to write in English about the primitive watercraft he observed in use there. In his 1697 account of his trip, A New Voyage Round the World, he wrote and these are but one Log, or two, sometimes of a sort of light Wood. So small, that they carry but one Man, whose legs, however, the unusual design met with skepticism and was not a commercial success. The design remained relatively unused in the West for almost 160 years until the early 19th-century, Crisp described it as a fast sailing fine sea boat, she traded during the monsoon between Rangoon and the Tenasserim Provinces for several years. Later that century, the American Nathanael Herreshoff constructed a sailing boat of his own design. The craft, Amaryllis, raced at her maiden regatta on June 22,1876 and her debut demonstrated the distinct performance advantages afforded to catamarans over the standard monohulls. It was as a result of event, the Centennial Regatta of the New York Yacht Club, that catamarans were barred from regular sailing classes. In 1936 Eric de Bisschop built a Polynesian double canoe in Hawaii, in 1939, he published his experiences in a book, Kaimiloa, which was translated into English in 1940. The Prout Brothers, Roland and Francis, experimented with catamarans in 1949 and converted their 1935 boat factory in Canvey Island, Essex and their Shearwater catamarans won races easily against the monohulls

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

Mystic Seaport
–
Mystic Seaport or Mystic Seaport, The Museum of America and the Sea in Mystic, Connecticut is the largest maritime museum in the United States. It is notable for its collection of sailing ships and boats and it consists of more than 60 original historic buildings, most of them rare commercial structures moved to the 19-acre site and meticulously restored. The museum was established in 1929 as the Marine Historical Association and its first fame came with the acquisition in 1941 of the Charles W. Morgan, the only surviving wooden sailing whaler. The seaport was one of the first living history museums in the United States, with a collection of buildings, the seaport now receives about 250,000 visitors each year. In addition, it supports research via a library. Munson Institute of American Maritime Studies, a summer academic program established in 1955 by maritime historian Professor Robert G. Albion of Harvard University. The Seaport also hosts Williams–Mystic in conjunction with Williams College, a program in maritime studies. Outreach includes sailing and history classes for area children, Mystic Seaport is a popular destination for boaters, who pay to dock overnight just a short walk away from ships such as the Charles W. Morgan and the fishing schooner L. A. Dunton. Four vessels at Mystic Seaport have been recognized by the United States Government as National Historic Landmarks The Preservation Shipyard is an important part of the museum. It is where tools and techniques are used to preserve the Museums collection of historic vessels. A replica of the slave ship La Amistad was constructed in the shipyard, the 19th-century seafaring village contains nearly all the types of general and specialized trades associated with building and operating a sailing fleet. They include a chandlery, sail loft, ropewalk, cooperage, shipping agents office, printing office, bank, also included is The Spouter Tavern, open seasonally and serving travelers fare. Demonstrations at the cooperage show how casks are assembled, one is a 1⁄128th scale model of the entire Mystic River area c.1870, complete down to the outhouse behind every residence, a model 40 feet long. Another contains a collection of carved ship figureheads, also among the museums buildings is a planetarium that demonstrates how seamen used stars for navigation. Sailing instruction is here, as well as tourist rides at nominal cost in various historical small craft. Such tours give an overview of historic ships at their moorings. Mystic Seaports music program is unusual as it prominently features sea shanties in their original contexts as work songs, regular sessions find shanty singers keeping museum visitors in line as they haul sails or turn a capstan. The Mystic Seaport Sea Music Festival, held annually in June since 1979, is among the oldest and largest in the United States, john Faunce Leavitt - former curator of Mystic Seaport

Gasoline
–
Gasoline /ˈɡæsəliːn/, known as petrol /ˈpɛtrəl/ outside North America, is a transparent, petroleum-derived liquid that is used primarily as a fuel in internal combustion engines. It consists mostly of organic compounds obtained by the distillation of petroleum. On average, a 42-gallon barrel of oil yields about 19 US gallons of gasoline when processed in an oil refinery. The characteristic of a gasoline blend to resist igniting too early is measured by its octane rating. Gasoline is produced in several grades of octane rating, sometimes, gasoline also contains ethanol as an alternative fuel, for economic or environmental reasons. Gasoline, as used worldwide in the vast number of combustion engines used in transport and industry, has a significant impact on the environment. Gasoline may also enter the environment uncombusted, as liquid and as vapors, from leakage and handling during production, transport and delivery, from tanks, from spills. As an example of efforts to control leakage, many storage tanks are required to have extensive measures in place to detect. Gasoline contains benzene and other known carcinogens, Gasoline inhalation can produce an intense high, however the practice is thought to cause severe organ damage, including mental retardation. The first automotive combustion engines, so-called Otto engines, were developed in the last quarter of the 19th century in Germany, the fuel was a relatively volatile hydrocarbon obtained from coal gas. With a boiling point near 85 °C, it was suited for early carburetors. The development of a spray nozzle carburetor enabled the use of less volatile fuels, further improvements in engine efficiency were attempted at higher compression ratios, but early attempts were blocked by knocking. In the 1920s, antiknock compounds were introduced by Thomas Midgley Jr. and Boyd and this innovation started a cycle of improvements in fuel efficiency that coincided with the large-scale development of oil refining to provide more products in the boiling range of gasoline. In the 1950s oil refineries started to focus on high octane fuels, the 1970s witnessed greater attention to the environmental consequences of burning gasoline. These considerations led to the out of TEL and its replacement by other antiknock compounds. Subsequently, low-sulfur gasoline was introduced, in part to preserve the catalysts in modern exhaust systems, Gasoline is the term that is used in North America to refer to the most popular automobile fuel. The Oxford English Dictionary dates the first use to 1863, when it was spelled gasolene and it was never a trademark, although it may have been derived from older trademarks such as Cazeline and Gazeline. Variant spellings of gasoline had been used to refer to raw petroleum since the 16th century, Petrol is the preferred term in most Commonwealth countries

Engine
–
An engine or motor is a machine designed to convert one form of energy into mechanical energy. Heat engines burn a fuel to heat, which is then used to create a force. Electric motors convert electrical energy into motion, pneumatic motors use compressed air. In biological systems, molecular motors, like myosins in muscles, use energy to create forces. The word engine derives from Old French engin, from the Latin ingenium–the root of the word ingenious. Pre-industrial weapons of war, such as catapults, trebuchets and battering rams, were called siege engines, the word gin, as in cotton gin, is short for engine. Most mechanical devices invented during the revolution were described as engines—the steam engine being a notable example. However, the steam engines, such as those by Thomas Savery, were not mechanical engines. In this manner, an engine in its original form was merely a water pump. Devices converting heat energy into motion are commonly referred to simply as engines, examples of engines which exert a torque include the familiar automobile gasoline and diesel engines, as well as turboshafts. Examples of engines which produce thrust include turbofans and rockets, the term motor derives from the Latin verb moto which means to set in motion, or maintain motion. Thus a motor is a device that imparts motion, motor and engine later came to be used largely interchangeably in casual discourse. However, technically, the two words have different meanings, however, rocketry uses the term rocket motor, even though they consume fuel. A heat engine may also serve as a prime mover—a component that transforms the flow or changes in pressure of a fluid into mechanical energy. An automobile powered by a combustion engine may make use of various motors and pumps. Another way of looking at it is that a motor receives power from an external source, simple machines, such as the club and oar, are prehistoric. More complex engines using human power, animal power, water power, wind power and these were used in cranes and aboard ships in Ancient Greece, as well as in mines, water pumps and siege engines in Ancient Rome. The writers of those times, including Vitruvius, Frontinus and Pliny the Elder, treat these engines as commonplace, by the 1st century AD, cattle and horses were used in mills, driving machines similar to those powered by humans in earlier times

Cruising (maritime)
–
Cruising by boat is a lifestyle that involves living for extended time on a vessel while traveling from place to place for pleasure. Cruising generally refers to trips of a few days or more, boats were almost exclusively used for working purposes prior to the nineteenth century. The modern conception of cruising for pleasure was first popularised by the Scottish explorer and he was introduced to the canoes and kayaks of the Native Americans on a camping trip in 1858, and on his return to the United Kingdom constructed his own double-ended canoe in Lambeth. The boat, nicknamed Rob Roy after a relative of his, was built of lapstrake oak planking. He cruised around the waterways of Britain, Europe and the Middle East and wrote a book about his experiences. In 1866, Macgregor was a force behind the establishment of the Royal Canoe Club. The first recorded regatta was held at on 27 April 1867, the latter part of the century saw cruising for leisure being enthusiastically taken up by the middle class. The author Robert Louis Stevenson wrote An Inland Voyage in 1877 as a travelogue on his trip through France. Stevenson and his companion, Sir Walter Grindlay Simpson travelled in two Rob Roys along the Oise River and witnessed the Romantic beauty of rural Europe. The Canadian-American Joshua Slocum was one of the first people to carry out a long-distance sailing voyage for pleasure, despite opinion that such a voyage was impossible, Slocum rebuilt a derelict 37-foot sloop Spray and sailed her single-handed around the world. His book Sailing Alone Around the World was a classic adventure, other cruising authors have provided both inspiration and instruction to prospective cruisers. Key among these during the post World War II period are Electa and Irving Johnson, Miles and Beryl Smeeton, Bernard Moitessier, Peter Pye, the development of ocean crossing rallies, most notably the ARC, have encouraged less experienced sailors to undertake ocean crossings. These rallies provide a group of crossing the same ocean at the same time with safety inspections, weather information. Many cruisers are long term and travel for many years, the most adventurous among them circle the globe over a period of three to ten years, many others take a year or two off from work and school for shorter trips and the chance to experience the cruising lifestyle. Blue-water cruising is more involved and inherently more dangerous than coastal cruising, before embarking on an open-ocean voyage, planning and preparation will include studying charts, weather reports/warnings, almanacs and navigation books of the route to be followed. In addition, the needs to be well trained at working together. Finally, the sailor must be prepared for dealing with harsh situations. There have been many well-documented cases where sailors had to be rescued simply because they were not sufficiently prepared or lacked experience for their venture, Sailing near the coast gives a certain amount of safety

Sloop
–
A sloop is a sailing boat with a single mast and a fore-and-aft rig. A sloop has only one head-sail, if a vessel has two or more head-sails, the cutter is used, and its mast may be set further aft than on a sloop. The most common rig of modern sailboats is the Bermuda-rigged sloop, typically, a modern sloop carries a mainsail on a boom aft of the mast, with a single loose-footed head-sail forward of the mast. Sloops are either masthead-rigged or fractional-rigged, on a masthead-rigged sloop, the forestay attaches at the top of the mast. The mainsail may be smaller than the headsail, which is called a genoa jib. On a fractional-rigged sloop, the forestay attaches to the mast at a point below the top, typically 3/4 of the way to top, or perhaps 7/8 or some other fraction. The mast of a fractional-rigged sloop may be placed forward, compared to a masthead-rigged sloop. After the cat rig, which has only a mainsail, the rig is one of the simpler sailing rig configurations. A sloop typically has two sails, a mainsail and a headsail, while the cutter has a mainsail and two or more headsails, next in complexity are the ketch, the yawl and the schooner, each of which has two masts and a minimum of three sails. A sloop has a system of mast rigging — a forestay. By having only two sails, the sails of a sloop are larger than those of an equivalent cutter. Until the advent of lightweight sailcloth and modern sail-handling systems, the sails of a sloop could be a handful. So, until the 1950s, sailboats over 10 metres Length Over All would typically use a rig or a two-mast rig. After the advent of modern winches and light sailcloth, the became the dominant sailing rig type for all. No rig type is perfect for all conditions, sloops, with their paucity of spars and control lines tend to impart less aerodynamic drag. Compared to other rigs, sloops tend to very well when sailing close hauled to windward. Cutters, ketches and yawls are often preferred to sloops when venturing far offshore, because it is easier to reef small sails as the wind increases, while still keeping the boat balanced. To maximize the amount of sail carried, the classic sloop may use a bowsprit, for downwind sailing, the typical foresail may be replaced by larger curved sails known as spinnakers or gennakers

One-Design
–
One-Design is a racing method which may be adopted in sports which use complex equipment, whereby all vehicles, gliders or boats have identical or very similar designs or models. In motor racing, it is known as Spec series. One-Design racing is the result of this. Most often, the members of a One-Design class are identical as a direct consequence of all deriving from the same production line. Sometimes they are checked or measured at stages in their use to guarantee continuing conformity to the standard design, the important factors being measured in One-Design racing help to equalize the vehicles and put more emphasis on the skill of the competitors. One-Design is utilized in a variety of racing sports and it is heavily used in sailboat racing. All competitors in a One-Design race are judged simply on a first to the finish basis using a single start time, in the United States, the One-Design Class Council creates, monitors, and enforces the rules that define what classes of sailboats are One-Design boats. In motorsport, this term is known as one-make racing. There are two methods of competition in sailboat racing, One-Design and handicap. One-design refers to a class that consists of just one model or design of sailboat. In one-design racing, the first boat to finish wins the race and this is contrasted with handicap racing, where time is added or subtracted from the finishing times based on design factors and mathematical formulas to determine the winner. In between One-Design and handicap racing, a number of approaches exist. One-Design can be contrasted with a development class, the example being the Americas Cup 12-metre class, or to the Box Rule used, for example. A further category, the formula based class setup, is confused with one-design. The Mini Transat 6.50, the Volvo Open 70 monohull, the large ORMA trimaran, class-legal boats race each other without any handicap calculations in both setups. As a result, the identifier One-Design has been used more and more exclusively to denote a class that races only identical boats, having a rigid one-design specification keeps design experimentation to a minimum and reduces cost of ownership. The popularity of one-design increased in the 1970s with the introduction of construction using fibre-reinforced plastic. This process allowed the production of identical hulls of virtually any size at a lower price

New England
–
New England is a geographical region comprising six states of the northeast United States, Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. It is bordered by the state of New York to the west and south, the Atlantic Ocean is to the east and southeast, and Long Island Sound is to the south. Its largest metropolitan area is Greater Boston, which also includes Worcester, Manchester, ten years later, more Puritans settled north of Plymouth Colony in Boston, thus forming Massachusetts Bay Colony. Over the next 126 years, people in the region fought in four French and Indian Wars, until the British and their Iroquois allies defeated the French and their Algonquin allies in North America. In 1692, the town of Salem, Massachusetts and surrounding areas experienced one of the most infamous cases of hysteria in the history of the Western Hemisphere. The Boston Tea Party was a protest to which Britain responded with a series of punitive laws stripping Massachusetts of self-government, the confrontation led to the first battles of the American Revolutionary War in 1775, and the expulsion of the British authorities from the region in spring 1776. Each state is subdivided into small incorporated municipalities known as towns. The only unincorporated areas in the region exist in the populated northern regions of Vermont, New Hampshire. The region is one of the U. S. Census Bureaus nine regional divisions, the earliest known inhabitants of New England were American Indians who spoke a variety of the Eastern Algonquian languages. Prominent tribes included the Abenaki, Mikmaq, Penobscot, Pequot, Mohegans, Narragansett Indians, Pocumtuck, prior to the arrival of Europeans, the Western Abenakis inhabited New Hampshire, New York, and Vermont, as well as parts of Quebec and western Maine. Their principal town was Norridgewock in present-day Maine, the Penobscot lived along the Penobscot River in Maine. The Narragansett and smaller tribes under Narragansett sovereignty lived in most of modern-day Rhode Island, west of Narragansett Bay, the Wampanoag occupied southeastern Massachusetts, Rhode Island, and the islands of Marthas Vineyard and Nantucket. The Pocumtucks lived in Western Massachusetts, and the Mohegan and Pequot tribes in the Connecticut region, the Connecticut River Valley includes parts of Vermont, New Hampshire, Massachusetts, and Connecticut, and linked different indigenous communities culturally, linguistically, and politically. As early as 1600, French, Dutch, and English traders began exploring the New World, trading metal, glass, on April 10,1606, King James I of England issued a charter for each of the Virginia Companies, London and Plymouth. These were privately funded ventures, intended to land for England, conduct trade. In 1620, Plymouth in present-day Massachusetts was settled by Pilgrims from the Mayflower, in 1616, English explorer John Smith named the region New England. As the first colonists arrived in Plymouth, they wrote and signed the Mayflower Compact, the Massachusetts Bay Colony came to dominate the area and was established by royal charter in 1629 with its major town and port of Boston established in 1630. Massachusetts Puritans began to settle in Connecticut as early as 1633, roger Williams was banished from Massachusetts for heresy, led a group south, and founded Providence Plantation in the area that became the Colony of Rhode Island and Providence Plantations in 1636

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

Rousmaniere writes on a range of topics but may be best known for his books on storms at sea, boating safety, yachting history. His sailing manual, The Annapolis Book of Seamanship, has gone through four editions since its publication in 1983. The considerably revised and updated edition was published in January 2014. A video series of the title is based on the book. Rousmenieres Fastnet, Force 10 is his account of sailing in the tragic 1979 Fastnet Race. Published in several languages and still in print in 2016, this was the first of his two storm books. His experiences in and about the Fastnet Race storm led him to attend Union Theological Seminary and he retired as a safety seminar moderator in 2016. Rousmaniere co-organized the Crew Overboard Rescue Seminar at Sausalito, Cal. in 2005 and wrote its final report recommending rescue equipment and he later served as coordinator of the Hanson Rescue Medal Award presented by US SAILING. In 2011 he served on Independent Review Panels in US Sailing Association inquiries into two fatal sailing accidents, one involving the death of a sailor in a 420 dinghy at Annapolis. And the other the deaths of two sailors in the Chicago Yacht Clubs race to Mackinac Island, on Lake Michigan, the reports are available on the US Sailing website. He has also written about maritime photography, for many years he was Consulting Editor of The Dolphin Book Club, the maritime division of the Book of the Month Club.
