Genoa (sail)
–
The genoa is a type of large jib or staysail that overlaps the main sail, sometimes eliminating it. It was originally referred to as a jib and later as a Genoa jib. It is used on single-masted sloops and twin-masted boats such as yawls and its larger surface area increases the speed of the craft in light to moderate winds, in high wind conditions a smaller jib is usually substituted, and downwind a spinnaker may be used. The feature that distinguishes a genoa from a working jib is that the former extends past the mast, the term jib is the generic term for any of an assortment of headsails. Colloquially the term is used interchangeably with jib. A working jib is no larger than the 100% foretriangle, a genoa is larger, with the leech going past the mast and overlapping the mainsail. To maximize sail area, the foot of the sail is generally parallel, genoas are categorized by a percentage representing their area relative to the 100% foretriangle. Sail racing classes often specify a limit to genoa size, genoas are classified by their size, a modern number 1 genoa would typically be approximately 155%, but historically number 1 genoas have been as large as 180%. Number 2 genoas are generally in the range of 125–140%, working jibs are also defined by the same measure, typically 100% or less of the foretriangle. Under Performance Handicap Racing Fleet rules, most boats are allowed 155% genoas without a penalty, maximizing the sail area can cause more difficult handling. It may be harder to tack a genoa than a jib, the gennaker has been around for several decades now, and as the name suggests, it is a hybrid between a genoa and an asymmetrical spinnaker. A brand name of North Sails, the started as a cruising sail based on the Code 0 spinnakers used on racing boats. Gennakers and similar code 0 variants offered by other makers are even larger than genoas, flat-cut gennakers can be effective for angles as low as 60–70 degrees. Spinnakers perform much better when running because the main sail blocks the wind of gennaker above 135–150 degrees, the famous Swedish sailor and shipowner Sven Salén first used the genoa on his 6 m R-yacht May-Be by the 1926 in Coppa di Terreno in Genua, hence the name. He successfully used it during the Scandinavian Gold Cups races of 1927 in Oyster Bay, Sven Salén also pioneered the parachute spinnacre. A similar type of jib was in use for centuries by the fishermen in the Netherlands with their Botter type ships, the fishermen relied on the combination of a large jib while fishing so the mainsail could remain unused. After fishing the fishermans jib helped to get the fish to markets fast, a correct explanation of the interaction between jib and mainsail was published by aerodynamicist and yachtsman Arvel Gentry in 1981, and is much more complicated than the old theories imply. This states that the widely believed explanation of the effect is completely wrong

Fore-and-aft rig
–
A fore-and-aft rig is a sailing rig consisting mainly of sails that are set along the line of the keel rather than perpendicular to it. Such sails are described as fore-and-aft rigged, fore-and-aft rigged sails include staysails, Bermuda rigged sails, gaff rigged sails, gaff sails, gunter rig, lateen sails, lug sails, the spanker sail on a square rig and crab claw sails. Northern Europeans were resistant to adopting the fore-and-aft rig, despite having seen its use in the course of trade, the lateen sail was more maneuverable and speedier, while the square rig was clumsy but seaworthy
3.
Bowsprit
–
The bowsprit of a sailing vessel is a spar extending forward from the vessels prow. It provides a point for the forestay, allowing the fore-mast to be stepped farther forward on the hull. The word bowsprit is thought to originate from the Middle Low German word bōchsprēt - bōch meaning bow, early ocean-going vessels tended to tilt the bowsprit, also known in centuries past as a boltsprit, at a high angle, and hung one or two square spritsails from yards. Many types of pleasure and work vessels ship bowsprits, generally short in length. Once popular on large and small, even after the popularization of the Bermuda rig. On some modern racing yachts and dinghies, the bowsprit is retractable, the bowsprit on a tall ship may be of considerable length and carry several forestays supporting the foremast. Headsails are stowed by tying onto the bowsprit when not in use, to minimise the risk of bowsprit and crew handling sail on it being buried in large waves, it is normally angled upwards from the horizontal. Some hang gliders use a bowsprit, rather than a spar to spread their wings, the bowsprit is formed by extending the keel tube about a metre beyond the leading edge of the wing. In 1879 a patent in England by F. W. Brearey was filed that taught bowsprit structure for flying machines, in the modern mid-1900s renaissance in hang gliding a Dial Soap TV commercial featured in 1973 a bowsprit cross-sparless hang glider. Other examples of bowsprit hang gliders were exampled in the manufactured by Bautek in the 1980s

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

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

Maritime pilot
–
A pilot, also referred to as a marine pilot, maritime pilot, or harbor pilot is a mariner who manoeuvres ships through dangerous or congested waters, such as harbors or river mouths. Since the pilot is on board the ship, he controls the tugs and linesmen through a radio, the ships captain ensures his crew carry out the pilots orders. Even if a ship Captain is a visitor to a certain Port, he can not match the expertise. In an unfortunate case of an accident, high pollution is a risk as the ships carry thousands of tonnes of fuel for her own consumption. Also if a ship is wrecked in the channel, the channel, legally, the master has full responsibility for safe navigation of his vessel, even if a pilot is on board. Only in transit of the Panama Canal and in Canada does the pilot have the responsibility for the navigation of the vessel. In English law, Section 742 of the Merchant Shipping Act 1894 defines a pilot as any person not belonging to a ship who has the conduct thereof. In other words, someone other than a member of the crew who has control over the speed, direction, the current United Kingdom legislation governing pilotage is the Pilotage Act 1987. Pilotage is one of the oldest professions, as old as sea travel, the oldest recorded history dates back to about the 7th century BC. The economic and environmental risk from large cargo ships makes the role of the pilot essential. Eventually, because the act of pilotage needed to be regulated and to ensure pilots had adequate insurance. The California Board of Pilot Commissioners was the first government agency created by Californias legislature, before harbour boards were established, pilots known as hobblers would compete with one another. The first to reach a ship would navigate it to the docks. In Dún Laoghaire, Ireland, there is a monument to the hobblers who lost their lives, in Kent they were known as hovellers and worked alongside and in competition with the licensed pilots, but were sometimes blamed as wreckers. George Byng Gattie defends the hovellers or hobilers as lifesavers in his 1890 book about the Goodwin Sands, although licensed by the harbour to operate within their jurisdiction, pilots were generally self-employed, and so had to have quick transport to get from the port to the incoming ships. As pilots were often still dual-employed, they used their own fishing boats to reach the incoming vessels, but fishing boats were heavy working boats, and filled with fishing equipment, hence a new type of boat was required. Early boats were developed from single-masted cutters and twin-masted yawls, and these were effectively light-weight and over-powered single masted boats with large steeply angled keels, making them deep draft under power and shallow draft in lighter sail. Joseph Henderson was an early American harbor pilot and he is well known for being a Sandy Hook Pilot for the New York harbor and along the Atlantic Coast during the Civil War

United States Coast Guard
–
The United States Coast Guard is a branch of the United States Armed Forces and one of the countrys seven uniformed services. This has happened twice, in 1917, during World War I, created by Congress on 4 August 1790 at the request of Alexander Hamilton as the Revenue Marine, it is the oldest continuous seagoing service of the United States. As Secretary of the Treasury, Hamilton headed the Revenue Marine, by the 1860s, the service was known as the U. S. Revenue Cutter Service and the term Revenue Marine gradually fell into disuse, the modern Coast Guard was formed by a merger of the Revenue Cutter Service and the U. S. Life-Saving Service on 28 January 1915, under the U. S. Department of the Treasury. As one of the five armed services, the Coast Guard has been involved in every U. S. war from 1790 to the Iraq War. As of 2014 the Coast Guard had over 36,000 men and women on duty,7,350 reservists,29,620 auxiliarists. In terms of size, the U. S. Coast Guard by itself is the worlds 12th largest naval force. Because of its authority, the Coast Guard can conduct military operations under the U. S. Department of Defense or directly for the President in accordance with Title 14 USC 1–3. The Coast Guards enduring roles are maritime safety, security, to carry out those roles, it has 11 statutory missions as defined in 6 U. S. C. §468, which include enforcing U. S. law in the worlds largest exclusive economic zone of 3.4 million square miles, the Coast Guards motto is the Latin phrase, Semper Paratus. In a 2005 article in Time magazine following Hurricane Katrina, the author wrote, the Coast Guards most valuable contribution to may be as a model of flexibility, and most of all, spirit. Wil Milam, a swimmer from Alaska told the magazine, In the Navy. Practicing for war, training for war, in the Coast Guard, it was, take care of our people and the mission will take care of itself. The Coast Guard carries out three basic roles, which are subdivided into eleven statutory missions. Both agencies maintain rescue coordination centers to coordinate this effort, and have responsibility for military and civilian search and rescue. The two services jointly provide instructor staff for the National Search and Rescue School that trains SAR mission planners and coordinators, previously located on Governors Island, New York, the school is now located at Coast Guard Training Center Yorktown at Yorktown, Virginia. The NRC also takes Maritime Suspicious Activity and Security Breach Reports, details on the NRC organization and specific responsibilities can be found in the National Oil and Hazardous Substances Pollution Contingency Plan. The Marine Information for Safety and Law Enforcement database system is managed and used by the Coast Guard for tracking pollution, the five uniformed services that make up the U. S

Border Force
–
Border Force is a part of the Home Office, responsible for frontline border control operations at air, sea and rail ports in the United Kingdom. The force was part of the now defunct UK Border Agency from its establishment in 2008 until Home Secretary Theresa May demerged it in March 2012 after severe criticism of the senior management. Since 1 March 2012, Border Force has been a law-enforcement command within the Home Office, the work of the Border Force is monitored by the Independent Chief Inspector of Borders and Immigration. Immigration officers have powers of arrest and detention conferred on them by the Immigration Act 1971, Border Force officers, designated as customs officials under the Borders, Citizenship and Immigration Act 2009, have wide-ranging powers of entry, search, seizure and arrest. They hold the same customs and excise powers as officers of HM Revenue and Customs, amongst their powers is the ability to arrest anyone who has committed, or who the officer has reasonable grounds to suspect has committed, any offence under the Customs and Excise Acts. They may also seize prohibited and restricted goods, such as controlled drugs and firearms, on 10 July 2012, Immigration Minister Damian Green confirmed that Moore had not applied for the post, despite Moore earlier telling the Home Affairs Select Committee that he would be applying. Tony Smith was appointed as interim Director General of Border Force on 19 September 2012, Smith was previously Gold Commander for the London 2012 Olympic Programme and Regional Director for London and the South East in the UK Border Agency. And has spent forty years in control and enforcement work. Vice-Admiral Sir Charles Montgomery was named as the new Director General on 25 January 2013, Border Force has five operational regions, Central, Heathrow, North, South, and South East & Europe. The regions have responsibility for securing the border 24 hours a day,365 days a year at the UK’s ports, airports, postal depots and this includes the Eurostar from Brussels and Paris to St Pancras International and the Eurotunnel from Coquelles to Folkestone. The regions’ varied work includes stopping 100 per cent of passengers arriving at ports or airports for immigration controls, officers also conduct risk-led interceptions for controlled drugs, cash, tobacco, alcohol, firearms, offensive weapons, prohibited goods, counterfeit goods and clandestine entrants. They do this at passenger and freight controls, covering passengers travelling on foot, by car, coaches, freight vehicles, as well as air freight, uniformed Border Force officers have their rank displayed on shoulder epaulettes, attached to their shirt, jumper or jacket. Warranted officers below Senior Officer rank may also have their identification number displayed, Border Force uniform is navy blue and, currently, modelled on the Metropolitan Police uniform. Border Force officers can make use of armour and carry handcuffs. Limb restraints are also in circulation, officers also carry Tetra radios on the secure Airwave network, often with earpieces, to communicate with other officers. In addition, officers may carry other useful police equipment. Torches currently issued, depending on location and job role, include Lenser LED P7.2 and Maglite LED 2D & 3D Cell varieties due to their performance, reliability, specialist forgery detection equipment is available at ports and airports to identify false passports and identity documents. Customs officials make use of a variety of specialised tools and equipment when searching cars, lorries, aircraft, container ships, all vessels of the Border Force bear the ship prefix HMC—Her Majestys Cutter

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
