Reliance (yacht)
–
Reliance was the 1903 Americas Cup defender, the fourth defender from the famous designer Nat Herreshoff, and reportedly the largest gaff-rigged cutter ever built. Reliance was designed to take advantage of the Seawanhaka 90-foot rating rule and was regarded as a racing freak. The 1903 Americas Cup was the last to be raced according to the Seawanhaka rule, to save weight, she was completely unfinished below deck, with exposed frames. She was the first racing boat to be fitted with winches below decks, despite this she carried a crew of 64 for racing due to her large sail plan. From the tip of her bowsprit to the end of her 108-foot boom, Reliance measured 201 feet, and the tip of her mast was 199 feet above the water. Everything else was to a gargantuan scale, her spinnaker pole was 84 feet long. Reliance was built for one purpose, to defend the Americas Cup. Her racing career was extraordinarily brief – and undefeated, there was much speculation as to whether Reliances victory was due to the design of the yacht or the skill of Charlie Barr in sailing her. Lipton himself proposed to allow the two boats to swap crew after the race to decide the matter, but the offer was refused by the owners of Reliance and her very successful career was short-lived, and she was sold for scrap in 1913

America's Cup
–
The Americas Cup, affectionately known as the Auld Mug, is a trophy awarded to the winner of the Americas Cup match races between two sailing yachts. The timing of each match is determined by an agreement between the defender and the challenger, the Americas Cup is the oldest international sporting trophy. The ewer was originally awarded in 1851 by the Royal Yacht Squadron for a race around the Isle of Wight in England, any yacht club that meets the requirements specified in the deed of gift has the right to challenge the yacht club that holds the cup. If the challenging club wins the match, it gains stewardship of the cup, the history and prestige associated with the Americas Cup attracts not only the worlds top sailors and yacht designers but also the involvement of wealthy entrepreneurs and sponsors. It is a test not only of sailing skill and boat and sail design, from the first defense of the cup in 1870 through the twentieth defense in 1967, there was always only one challenger. Since 1983, Louis Vuitton has sponsored the Louis Vuitton Cup as a prize for the winner of the challenger selection series, early matches for the cup were raced between yachts 65–90 ft on the waterline owned by wealthy sportsmen. This culminated with the J-Class regattas of the 1930s, after a long legal battle, the 2010 Americas Cup was raced in 90 ft lwl multihull yachts in a best of three deed of gift match in Valencia, Spain. The victorious Golden Gate Yacht Club then elected to race the 34th Americas Cup in AC72 foiling, Golden Gate Yacht Club successfully defended the cup. The 35th Americas Cup match was announced to be sailed in 50 ft foiling catamarans, the history of the Americas Cup has included legal battles and disputes over rule changes including most recently over the rule changes for the 2017 Americas Cup. It was originally known as the R. Y. S, £100 Cup, standing for a cup of a hundred GB Pounds or sovereigns in value. The cup was subsequently mistakenly engraved as the 100 Guinea Cup by the America syndicate, today, the trophy is officially known as the Americas Cup after the 1851 winning yacht, and is affectionately called the Auld Mug by the sailing community. It is inscribed with names of the yachts that competed for it, the syndicate contracted with pilot boat designer George Steers for a 101 ft schooner, which was christened America and launched on 3 May 1851. On 22 August 1851, America raced against 15 yachts of the Royal Yacht Squadron in the Clubs annual 53-nautical-mile regatta around the Isle of Wight, America won, finishing 8 minutes ahead of the closest rival. Apocryphally, Queen Victoria, who was watching at the line, was reported to have asked who was second. No challenge to race for the Cup was issued until British railway tycoon James Lloyd Ashburys topsail schooner Cambria beat the Yankee schooner Sappho in the Solent in 1868. This success encouraged the Royal Thames Yacht Club in believing that the cup could be back home. Ashbury entered Cambria in the NYYC Queens Cup race in New York City on 8 August against a fleet of seventeen schooners, the Cambria only placed eighth, behind the aging America in fourth place and Franklin Osgoods Magic in the fleets lead. Trying again, Ashbury offered a match race challenge for October 1871

Sailing
–
Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the water, on ice or on land over a chosen course, which is often part of a larger plan of navigation. A course defined with respect to the wind direction is called a point of sail. Conventional sailing craft cannot derive power from sails on a point of sail that is too close into the wind, on a given point of sail, the sailor adjusts the alignment of each sail with respect to the apparent wind direction to mobilize the power of the wind. In the 21st century, most sailing represents a form of recreation or sport, recreational sailing or yachting can be divided into racing and cruising. Cruising can include extended offshore and ocean-crossing trips, coastal sailing within sight of land, until the end of the 19th century, sailing ships were the primary means for marine commerce. The earliest representation of a ship under sail appears on a painted disc found in Kuwait dating between 5000 and 5500 BCE, polynesian oceanfarers traveled vast distances of open ocean in outrigger canoes using navigation methods such as stick charts. Advances in sailing technology from the Middle Ages onward enabled Arab, Chinese, Indian and European explorers to make longer voyages into regions with extreme weather and climatic conditions. There were improvements in sails, masts and rigging, improvements in marine navigation including the tree and charts. Sailing has contributed to many great explorations in the world, the air interacting with the sails of a sailing vessel creates various forces, including reaction forces. If the sails are properly oriented with respect to the wind, however, boats propelled by sails cannot sail directly into the wind. They must tack back and forth in order to progress directly upwind, sails are airfoils that work by using an airflow set up by the wind and the motion of the boat. Sails work in two modes to use the wind to force, PUSH, when the boat is going in the same direction as the wind. The force on the sail is mostly aerodynamic drag, and sails acting in this way are aerodynamically stalled. This force manifests itself as pressure differences between the two sides of the sail - there is a region of low pressure on the front side of the sail and a region of high pressure on the back. Another way to say this is that sails generate lift using the air flows around them in the same way as an aircraft wing. The wind that a boat experiences is the combination of the true wind and this combination is the apparent wind, which is the relative velocity of the wind relative to the boat. When sailing upwind the apparent wind is greater than the true wind, iceboats can typically sail at 5 times the speed of the wind. Where there is a difference in motion, then there is energy to be extracted at the interface, the sailboat does this by placing the sail in the air and the hull in the water

Sail
–
A sail derives power from the wind to provide motive power for sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and sail-powered land vehicles. Sails mobilize lift and drag properties as air passes along the surface, in most cases sails are supported directly by a mast rigidly attached to the sailing craft or on a wire stay attached to the mast, however some craft employ a flexible mount for a mast. Sails also employ spars and battens to help determine their shape, as a result, sails come in a variety of shapes that include both triangular and quadrilateral configurations, usually with curved edges that promote three-dimensional curvature of the sail. Kites also power certain sailing craft, but do not employ a mast to support the airfoil and are beyond the scope of this article, sailing craft employ two types of rig, the square rig and the fore-and-aft rig. The square rig carries the primary driving sails are carried on horizontal spars and these spars are called yards and their tips, beyond the last stay, are called the yardarms. A ship mainly so rigged is called a square-rigger, the square rig is aerodynamically most efficient when running. A fore-and-aft rig consists of sails that are set along the line of the rather than perpendicular to it. Vessels so rigged are described as fore-and-aft rigged, archaeological studies of the Cucuteni-Trypillian culture ceramics show use of sailing boats from the sixth millennium onwards. Excavations of the Ubaid period in Mesopotamia provides direct evidence of sailing boats, Sails from ancient Egypt are depicted around 3200 BCE, where reed boats sailed upstream against the River Niles current. Ancient Sumerians used square rigged sailing boats at about the same time, the proto-Austronesian words for sail, lay, and other rigging parts date to about 3000 BCE when this group began their Pacific expansion. Greeks and Phoenicians began trading by ship by around 1,200 BCE, northern Europeans were resistant to adopting the fore-and-aft rig, despite having seen its use in the course of trade and during the Crusades. The lateen sail proved to have better performance for smaller vessels. Aerodynamic forces on sails depend on speed and direction and the speed. The direction that the craft is traveling with respect to the wind is called the point of sail. The speed of the craft at a point of sail contributes to the apparent wind —the wind speed. Depending on the alignment of the sail with the apparent wind, for apparent wind angles aligned with the entry point of the sail, the sail acts as an airfoil and lift is the predominant component of propulsion. For apparent wind angles behind the sail, lift diminishes and drag increases as the predominant component of propulsion, because of limitations on speed through the water, displacement sailboats generally derive power from sails generating lift on points of sail that include close-hauled through broad reach. Downwind sailing with a spinnaker Each rig is configured in a 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

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

Sail components
–
Sail components include the features that define a sails shape and function, plus its constituent parts from which it is manufactured. A sail may be classified in a variety of ways, including by its orientation to the vessel and its shape. Sails are typically constructed out of material that is shaped by various means, while in use, to offer an appropriate airfoil, according to the strength. A variety of features and fittings allow the sail to be attached to lines and they also may be classified as symmetrical or asymmetrical. Triangular sails have names for each of three edges and three corners, rigs with such sails include Bermuda, cutter, lateen and vessels with mixed sail plans that include jibs and other staysails. Most triangular sails are classified as asymmetrical and fore and aft, gaff, gunter, lug, junk and some sprit sails have four sides and are set fore and aft so that one edge is leading into the wind. Naming conventions are consistent with triangular sails, except for the top edge and these spars are called yards and their tips, beyond the last stay, are called the yardarms. A ship mainly so rigged is called a square-rigger, the shape of a sail is defined by its edges and corners in the plane of the sail, laid out on a flat surface. The edges may be curved, either to extend the sails shape as an airfoil or to define its shape in use, in use, the sail becomes a curved shape, adding the dimension of depth or draft. The top of all sails is called the head, the edge is called the luff, the trailing edge is the leech. Head – The head is the edge of the sail. For a triangular sail the head refers to the topmost corner, luff – The forward edge of a fore-and-aft sail is called the luff, which, in a mainsail, is parallel to the mast. In a symmetrical sail that leech, which is the edge into the wind. Foot – The foot of a sail is its bottom edge and this added area would flutter in the wind and not contribute to the efficient airfoil shape of the sail without the presence of battens. Offshore cruising mainsails sometimes have a hollow leech to obviate the need for battens and their ensuing likelihood of chafing the sail. Roach is a term applied to square sail design—it is the arc of a circle above a straight line from clew to clew at the foot of a square sail. The roach allows the foot of the sail to clear stays coming up the mast, the names of corners of sails vary, depending on shape and symmetry. Head – In a triangular sail, the corner where the luff, on a square sail, the top corners are head cringles, where there are grommets, called cringles
7.
Backstay
–
A backstay is a piece of standing rigging on a sailing vessel that runs from the mast to either its transom or rear quarter, counteracting the forestay and jib. It is an important sail trim control and has an effect on the shape of the mainsail. Backstays are generally adjusted by block and tackle, hydraulic adjusters, backstays may be permanent or running. A permanent backstay is attached to the top of the mast, running backstays appear in pairs attached about two-thirds of the way up the mast. In general, most modern sailboats will have a permanent backstay, backstays are not always found on all vessels, especially smaller ones. A permanent backstay is attached at the top of the mast, in a masthead rig, tensioning the permanent backstay will directly tension the forestay. This control is used to adjust the amount of sag in the headsail, increased mast bend tends to reduce the draft of the mainsail. A running backstay always attaches to the mast at a point below the top of the mast and is used in conjunction with a permanent backstay. Running backstays are found on both masthead rigs and fractional rigs, there are some rigs for which running backstays may be used without a permanent backstay. This occurs most often where the mainsail has a significant roach or a large mainsail. Gaff rigged boats invariably have running backstays with no permanent backstay, in both of these cases the mainsail extends aft of a line from masthead to stern, and so a permanent backstay would interfere with the operation of the sail. As a direct consequence of its attachment point a running backstay is always adjustable because it must be engaged and disengaged during every tack or jibe. Adjusting the tension on the running backstay has two effects, First, the forestay is tensioned and Second, mast bend is increased, the overall effect of tensioning the running backstay is a shallower mainsail combined with a reduction in headsail sag. Both effects are desirable as the wind increases

Bermudian 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

Schooner
–
A schooner /ˈskuːnər/ is a type of sailing vessel with fore-and-aft sails on two or more masts, the foremast being shorter than the main and no taller than the mizzen if there is one. While the schooner was originally gaff-rigged, modern schooners typically carry a Bermuda rig, such vessels were first used by the Dutch in the 16th or 17th century. They were further developed in North America from the early 18th century, the most common type, with two masts, were popular in trades requiring speed and windward ability, such as slaving, privateering, blockade running, and offshore fishing. In the Chesapeake Bay area several distinctive schooner types evolved, including the Baltimore clipper, bugeye, schooners were also popular among pirates in the West Indies during the Golden Age of Piracy, for their speed and agility. They could also sail in shallow waters, and while being smaller than other ships of the time period. Schooners first evolved in the late 17th century from a variety of small two-masted gaff-rigged vessels used in the coast, most were working craft but some pleasure yachts with schooner rigs were built for wealthy merchants and Dutch nobility. Following the arrival of the Dutch monarch William of Orange on the British throne and this vessel, captured in a detailed Admiralty model, is the earliest fully documented schooner. Royal Transport was quickly noted for its speed and ease of handling, North American shipbuilders quickly developed a variety of schooner forms for trading, fishing and privateering. According to the language scholar Walter William Skeat, the term comes from scoon. The Dutch word schoone means nice, good looking, robinson replied, A schooner let her be. The launch is variously described as being in 1713 or 1745, naval architects such as Howard Chapelle have dismissed this invention story as a childish fable, but some language scholars feel that the legend may support a Gloucester origin of the word. Other sources state the etymology as unknown and uncertain, the first detailed definition of a schooner, describing the vessel as two-masted vessel with fore and aft gaff-rigged sails appeared in 1769 in William Falconers, Universal Dictionary of the Marine. Although a schooner may have up to four masts, the schooner has only two, with the foremast shorter than the mainmast. There may be a bowsprit to help balance the rig, the principal issue with a schooner sail plan is how to fill the space between the two masts most effectively. Traditional schooners were rigged, and the trapezoid shape of the foresail occupied the inter-mast space to good effect, with a useful sail area. A Bermuda rigged schooner typically has four sails, a mainsail, a main staysail abaft the foremast, plus a forestaysail. An advantage of the schooner is that it is easily handled and reefed by a small crew. The main staysail will not overlap the mainsail, and so little to prepare the wind for the mainsail

Barquentine
–
A barquentine or schooner barque is a sailing vessel with three or more masts, with a square rigged foremast and fore-and-aft rigged main, mizzen and any other masts. The term barquentine is 17th century in origin, formed from barque in imitation of brigantine, a two-masted vessel square-rigged only on the forward mast, concordia, a sail training ship that capsized and sank on 17 February 2010. Mercator of 1932, Belgian training ship, transit, an experimental design of 1800 that could be worked entirely from the deck.

Spanker (sail)
–
A spanker is either of two kinds of sail. On a square rigged ship, the spanker is a gaff rigged fore-and-aft sail set from, almost all square rigs with more than one mast have one or two spankers, which evolved from the driver sail. Some also carry a triangular topsail above the uppermost or only spanker, a spanker in this situation is often soft footed in that it has no boom to which it is attached at its foot. On a racing or cruising yacht, a spanker is an additional headsail set beside and it is often of bright colours to match the particular spinnaker with which it is designed to be used, is relatively narrow, and is sometimes called a tallboy or blooper. Death roll, an undesirable broach to windward, countered by rigging a blooper
12.
Square rig
–
These spars are called yards and their tips, beyond the last stay, are called the yardarms. A ship mainly so rigged is called a square-rigger, the square rig is aerodynamically the most efficient running rig, and stayed popular on ocean-going sailing ships until the end of the Age of Sail. The last commercial sailing ships, windjammers, were usually square-rigged four-masted barques, square-rigged masts may also have triangular staysails that are deployed fore-and-aft between masts. Square-rigged is also used for the uniform of a rating in the Royal Navy since 1857 and it is slang and refers to anyone wearing the famous blue square collar on the shoulders and bell-bottomed trousers. The name perhaps reflects the fact that it was men who managed the square-rigged sails. The peaked cap worn by Senior Ratings and Officers is known colloquially as fore-and-aft rig. A mast is considered square-rigged if its lowest sail or course is square-rigged, if the course is fore-and-aft, square topsails can still be carried in front of the mast. In their heyday, square-rigged vessels ranged in size from small boats to full rigged ships, but this rig fell from favour to fore-and-aft gaff rigs and bermuda rigs after the development of steam power and new materials. Ocean-going sailing ships stayed mostly square-rigged, Square rigs allowed the fitting of many small sails to create a large total sail area to drive large ships. 18th century warships would often achieve speeds of 12–13 knots. Some clipper ships that had square rigs and for speed was critical could be much faster. The late windjammers were as fast as the clippers, being much bigger, not only could a smaller sail be managed by a smaller crew but also these smaller sails constrained the impact of weapons on them. A hole from a cannonball affected only one area, whilst a hole in a large sail would eventually tear the whole larger area. This reduced running costs and also enlarged the space available in the ship for profitable cargoes, new materials also changed sail designs, particularly on hybrid vessels carrying some square-rigged sails. The low aspect ratio of square-rigged sails produces much drag for the lift produced, so they have poor performance to windward compared to modern yachts, the Bermuda rig is the undisputed champion of windward performance in soft sails, due to its very low drag and high lift-to-drag ratio. One advantage of square rigs is that they are efficient when running, where the high lift to drag is irrelevant. Square-rigged sails are also prone to broaching when running than Bermuda rigs. Ocean-going vessels take advantage of e. g. the trade winds, on a square-rigged mast the sails had names which indicated their vertical position on the mast
13.
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
14.
Ketch
–
A ketch is a sailing craft with two masts. The distinguishing characteristic of a ketch is that the forward of the two masts is larger than the after mast, historically the ketch was a square-rigged vessel, most commonly used as a freighter or fishing boat in northern Europe, particularly in the Baltic and North seas. In modern usage, the ketch is a rigged vessel used as a yacht or pleasure craft. To assist going to windward, a ketch may carry one or more jibs or foresails, if a ketch has no jibs, it is called a cat ketch or a periauger. On older, larger ketches the main mast may in addition one or more square rigged topsails. The large fore-and-aft sail on the mainmast is the mainsail, while the sail on the mizzen mast is the mizzen and these sails may be any type of fore-and-aft sail, in any combination. Most modern ketches are Bermuda rigged, but other possible rigs on a ketch include gunter rigs, the Scots Zulu, for example, had a dipping lug main with a standing lug mizzen. In northern Europe and among long distance cruisers, the ketch is often preferred to a sloop, since the additional sail allows a balance. An advantage of the ketch is when sudden increases in wind strength require a rapid reefing, the ketch rig also allows sailing only on the mizzen and jib, without introducing excessive lee helm, and in an emergency can be quite well steered without use of the rudder. When running before the wind or reaching across the wind, a ketch may set extra sails such as a spinnaker on the main mast, and a spinnaker or mizzen staysail on the mizzen mast. Another advantage of a ketch is at anchor, where the sail may be used to hold the boat steady in the wind. The square-rigged ketch was largely supplanted by the brig, which differs from the ketch by having a forward mast smaller than the after mast, and by the hoy, other similar craft include the snow and the pink. But the balance of sail area can be an overriding characteristic, if 20% or more of the sail area is in the mizzen sail the rig would be termed a ketch. This is particularly true on center cockpit yachts, compared to a ketch, a similar size yawls mizzen sail is much smaller than the main, because of the limitations of the mizzen sheet. So on a ketch, the purpose of the mizzen sail is to both propel and balance the vessel, while on a yawl, the smaller mizzen mainly serves the purpose of trim or balance. Yawls tend to have mainsails almost as large as those of comparable sloops, a ketch may be distinguished from a cutter or a sloop by virtue of having two masts rather than one, though a ketch with two foresails is sometimes called a cutter-rigged ketch. Both the ketch and the yawl differ from the two-masted schooner, if a vessel has two masts of approximately the same height, the rig with the larger sail forward is called a ketch, while the rig with the larger sail aft is a schooner. The American two-masted schooner is rare in Europe, where the rig is preferred
15.
Yawl
–
The mizzen sail is hoisted on the mizzen mast. The yawl was originally developed as a rig for fishing boats. In its heyday, the ability to be trimmed to sail without rudder input made it particularly popular with single-handed sailors, such as circumnavigators Harry Pidgeon. Modern self-steering and navigation aids have made less important. A good example of this was Olin Stephens Finisterre, a small ships boat, usually rowed by four or six oars. To add a sailing rig to a rowboat, the masts must not interfere with the rowers, the mainmast is placed well forward and the mizzen as far back as possible. The mizzen has to be small in size to keep the sail area balanced around the centre of lateral resistance to ensure the boat will sail in a straight line without excessive correction. Both the yawl and the ketch have two masts, with the main mast foremost. On classic yacht types with long overhangs and inboard rudders, the distinction is simple, for boats with shorter overhangs or outboard rudders the distinction is more usefully determined by comparing the purposes and relative sizes of the mizzens. Compared to a ketch, a similar size yawls mizzen sail is much smaller than the main, and is usually situated very far aft, behind the helm station. On a ketch, the purpose of the mizzen sail is to help propel the vessel as part of the working sail. On a yawl, the smaller mizzen mainly serves the purposes of trim and balance, Yawls tend to have mainsails almost as large as those of sloops of comparable sized hulls. The common definition of Yawl and Ketch using the rudder post does not reflect the tradition and was created by much more recent developments of a handicap system for racing yachts. The CCA rating rule was developed following World War II to allow different styles of boats to race against each other with a handicap calculated from measurements of each boat. It was later combined with the RORC rule to become the IOR rule in the late 1950s which was used to handicap international racing until the late 1980s, canoe Yawls have a pointed stern similar to a canoe. Rudders were usually placed on the back of the boat which allows the rudder to be raised to allow the boat to be landed on a beach

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

Halyard
–
In sailing, a halyard or halliard is a line that is used to hoist a ladder, sail, flag or yard. The term halyard comes from the phrase, to haul yards, halyards, like most other parts of the running rigging, were classically made of natural fibre like manila or hemp. A square rig sail with a halyard is mounted on a yard that is free to slide on a short section of the mast. The halyard is used to raise the yard when setting the sail, a gaff rigged sail has two, a throat halyard to lift the end of the gaff nearer the mast, and a peak halyard to lift the outer end. A more modern triangular sail has only one halyard which is attached at its uppermost point, halyards can be attached a number of ways to the head of a triangular sail. The most common methods are as follows, A shackle through a headboard on the sail, a bowline through a hole in the head. A half hitch with a knot, preferred over a bowline because it allows the sail to get closer to the top of the mast. The other end of the halyard is attached to the mast at its foot by way of a cleat. It is convention in some places to fasten the main halyard on the side of the mast. This allows quicker access to the lines in a time-critical situation, jumping the halyard is a technique used to raise a large sail quickly by employing a few crew members to work simultaneously on the halyard. The person jumping stands next to the mast and manually grabs the halyard as high as he can and pulling it down as fast and far as possible. While this crew member reaches for the next heave, a crew member tails or takes up the slack created by the jumper. When the person jumping can no longer pull up the sail simply by hanging on the halyard, to sweat the halyard is to take as much slack out of it as possible. This may be done with a winch, or manually, to manually sweat a halyard, the sweater grasps the line and, in a fluid motion, hauls it laterally towards himself, then down toward the deck, letting the tailer take up the new slack

Topsail
–
A topsail is a sail set above another sail, on square-rigged vessels further sails may be set above topsails. On a square rigged vessel, a topsail is a sail rigged above the course sail. A full rigged ship has either single or double topsails on all masts, the single or lower topsail being the second sail above the deck, the bottom edge of the topsail, like that of other square sails, is slightly concave. Although topsails of a kind were used at least as early as Roman times, they first came into use in Europe some time in the 15th century. It was quite common for a ship to sail with topsails and jibs alone, the larger topsails were difficult and dangerous to handle in strong winds. Sometime in the 1680s, reef-bands were introduced to tie up part of the sail, with topsails eventually getting four of these, and reefing the sails became a regular occupation of sailors. In the mid 19th century, topsails of merchant vessels were split into upper and lower topsails that could be managed separately. Competing versions of the double topsail were invented by Robert Bennet Forbes, although Forbes strove to defend his rig, the Howe rig dominated. In the Forbes rig, both topsail yards are fixed vertically, in the Howe rig, the upper topsail yard slides on the topmast so it can be lowered in a few seconds to close reef the upper topsail. Howe had the foot of the upper topsail closely attached to the lower topsail yard, in 1865 the British clipper Ariel introduced a gap there. Forbes first tried his rig in the topsail schooner Midas in 1844. The clipper Climax built in 1853 under the supervision of Howes was the first ship with Howe rig, gaff topsails, like gaff rigs in general, may still be seen at Tall Ships gatherings. The gaff rig has been superseded by the Bermuda rig. On a gaff-rigged sailing boat, topsails may take a few different forms, a gaff-rigged vessel might have a gaff topsail above any or all of its gaff sails. A yard topsail is similar, but set on a yard, early 19th-century topsail yards were set almost horizontally, but gradually increased in angle until they became almost vertical extension of the topmast. A jack-yard topsail instead has its lower edge extended out beyond the end of the gaff with a short yard, a jack-yard topsail may also have the aforementioned vertical yard, although this makes for a very large topsail. A cornish topsail is a triangular sail having its luff extended well above the masthead by being laced to a yard hoisted by a halyard rove through a sheave fitted diagonally in the mast. The heel of the yard fits immediately about the gaff and is kept in place by a called a timminoggy. A square topsail is a sail, carried above the foresail only

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
