Spritsail
The spritsail is a four-sided, fore-and-aft sail that is supported at its highest points by the mast and a diagonally running spar known as the sprit. The foot of the sail can be stretched by a boom or held loose-footed just by its sheets. A spritsail has four corners: the throat, peak, clew, and tack. The Spritsail can also be used to describe a rig that uses a spritsail. Historically, spritsails were the first European fore-and-aft rigs, appearing in Greco-Roman navigation in the 2nd century BC. The rig The luff of the sail is bound to the mast, but unlike the gaff rig where the head is bound to a spar, this rig supports the leech of the sail by means of a diagonal spar or spars named a sprit ( ). The forward end of the sprit spar is attached to the mast, with the after end of the sprit spar attached to the peak. The sprit is steadied and controlled from the deck by a pair of wire vangs ( ) attached to the peak of the sail. It is said to be the ancestor of the common ...

Thames Sailing Barge
A Thames sailing barge is a type of commercial sailing boat once common on the River Thames in London. The flat-bottomed barges with a shallow draught and leeboards, were perfectly adapted to the Thames Estuary, with its shallow waters and narrow tributary rivers. The larger barges were seaworthy vessels, and were the largest sailing vessel to be handled by just two men. The average size was about 120 tons and they carried of canvas sail in six working sails. The mainsail was loose-footed and set up with a sprit, and was brailed to the mast when not needed. It is sheeted to a horse, as is the foresail; they require no attention when tacking. The foresail is often held back by the mate to help the vessel come about more swiftly. The topsail was usually first sail on and last sail off, being fixed to the topmast by hoops. In the upper reaches of the rivers and constricted harbours it reached into the clear air, and when approaching a berth casting off the halliard would drop ...

Optimist (dinghy)
The Optimist is a small, single-handed sailing dinghy intended for use by young people up to the age of 15. The Optimist is one of the two most popular sailing dinghies in the world, with over 150,000 boats officially registered with the class and many more built but never registered. It is sailed in over 120 countries and it is one of only two sailboats as an International Class by World Sailing exclusively for sailors under 16. Origin The Optimist was designed in 1947 by American Clark Mills at the request of the Clearwater Florida Optimist service club following a proposal by Major Clifford McKay to offer low-cost sailing for young people. The Optimist Club ran a soap box derby, but wanted more than a single-day event. Thus they were looking for a low-cost equivalent for sailing. He designed a simple pram that could be built from two 4' x 8' sheets of plywood, and donated the plan to the Optimists. The design was slightly modified and introduced to Europe by Axel Damga ...

Fore-and-aft Rig
A fore-and-aft rig is a sailing vessel rigged mainly with sails set along the line of the keel, rather than perpendicular to it as on a square rigged vessel. Description Fore-and-aft rigged sails include staysails, Bermuda rigged sails, gaff rigged sails, gaff sails, gunter rig, lateen sails, lug sails, tanja sails, the spanker sail on a square rig and crab claw sails. Fore-and-aft rigs include: * Rigs with one mast: the proa, the catboat, the sloop, the cutter * Rigs with two masts: the ketch, the yawl * Rigs with two or more masts: the schooner Barques and barquentines are partially square rigged and partially fore-and-aft rigged. A rig which combines both on a foremast is known as a hermaphroditic rig. History Austronesia The fore-and-aft rig is believed to have been first developed independently by the Austronesian peoples some time around 1500 BC with the invention of the crab claw sail. It is suggested that it evolved from a more primitive "V"-shaped "squ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cromster
The Crommesteven or cromsteven, often as crompster, cromster or crumster (from ''crom'' = bent, concave; ''steven'' = stem) was a type of small warship used by the Dutch Republic and later by the British fleets during the sixteenth and seventeenth centuries. It was designed for work inshore on the shoal Netherlands coast and was a ketch, spritsail rigged on the main, and lateen on the small mizzen. As a class of vessel, it was represented in England by the hoy. When queen Elizabeth I died in 1603, her navy was reported to consist of 31 great ships, including galleon Galleons were large, multi-decked sailing ships first used as armed cargo carriers by European states from the 16th to 18th centuries during the age of sail and were the principal vessels drafted for use as warships until the Anglo-Dutch W ...s and crompsters, though crommestevens were considerably smaller than galleons.Corbett, Julian Stafford: ''The successors of Drake'', London : Longmans, Green 1900. p.411 ...

Gaff Rig
Gaff rig is a sailing rig (configuration of sails, mast and stays) in which the sail is four-cornered, fore-and-aft rigged, controlled at its peak and, usually, its entire head by a spar (pole) 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 given hull design. A sail hoisted from a gaff is called a gaff-rigged (or, less commonly, gaff rigged or gaffrigged) sail. Description 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. On other rigs, particularly the sloop, ketch and yawl, gaff rigged sails were once common but have now been largely replaced by the Bermuda rig sail, which, in addition to be ...

Parts Of A Sail
Sail components include the features that define a sail's 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 (e.g. ''fore-and-aft'') and its shape, (e.g. ''(a)symmetrical'', ''triangular'', ''quadrilateral'', etc.). Sails are typically constructed out of flexible material that is shaped by various means, while in use, to offer an appropriate airfoil, according to the strength and apparent direction of the wind. A variety of features and fittings allow the sail to be attached to lines and spars. Whereas conventional sails form an airfoil with one layer of fabric, wingsails comprise a structure that has material on both sides to form an airfoil—much like a wing placed vertically on the vessel—and are beyond the scope of this article. Classifications Sails may be classified as either ''triangular'', which describes sails that either come to one point of suspen ...

Norfolk Wherry
The Norfolk wherry is a type of boat used on The Broads in Norfolk and Suffolk, England. Three main types were developed over its life, all featuring the distinctive gaff rig with a single, high-peaked sail and the mast stepped well forward. Development of the wherry Wherries were sail and oar craft dating back to at least 1604. These were small craft, in 1727 being of 8 tons net tonnage. They were still sail and oar boats, fitted with hoops and canvas tilts for the comfort of their passengers. They would have provided a service carrying passengers and small perishable cargoes. Alongside these early wherries were the bigger keels, which were transom-sterned clinker-built barges with a square sail on a mast stepped amidships of about by and able to carry 30 tons of goods. The keel had been built since the Middle Ages and the design probably went back to the Viking invasion. After 1800, the Norfolk Keel (or 'keel wherry') disappeared, partly because a wherry could be saile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
