Tempest (keelboat)
The Tempest is a trailerable, one-design racing sailboat that was designed by British naval architect Ian Proctor and first built in 1965.Sherwood, Richard M.: ''A Field Guide to Sailboats of North America, Second Edition'', pages 116-117. Houghton Mifflin Company, 1994. Production In the past the design was built by O'Day Corp. and Plastrend/Composite Technologies in the United States and by Lanaverre in France. A total of 850 boats had been reported as built by 1994. Today it is built by Mader Bootswerft of Germany and remains in production. Design The Tempest is a racing keelboat, built predominantly of fiberglass, with wood trim. It has a fractional sloop rig with aluminum spars. The hull has a spooned raked stem, a plumb transom, an internally mounted spade-type rudder controlled by a tiller and a lifting, weighted, bulb keel. It displaces and carries of lead keel ballast. Construction includes three transverse bulkheads to aid flotation. The boat has a rear dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ian Proctor
Ian Douglas Ben Proctor (12 July 1918 – 23 July 1992) was a British designer of boats, both sailing dinghies and cruisers. He had more than one hundred designs to his credit, from which an estimate of at least 65,000 boats were built. His pioneering aluminium mast designs also revolutionised the sport of sailing. Early life and education Proctor was a son of Douglas McIntyre Proctor and Mary Albina Louise Proctor (née Tredwen).''Who's Who? 2009 & Who Was Who'', Oxford University Press, 2009, online edition, 2009 He was educated at Gresham's School in Holt, Norfolk.''I Will Plant Me a Tree: an Illustrated History of Gresham's School'' by S.G.G. Benson and Martin Crossley Evans (James & James, London, 2002) p. 39 After leaving school, he studied at the University of London. In 1943, he married Elizabeth Anne Gifford Lywood, the daughter of Air Vice-Marshal O. G. Lywood, CB, CBE. They had three sons and a daughter. Proctor contracted Polio in Alexandria, and lived the remainder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trapeze (sailing)
In sailing, the trapeze is a wire that comes from a point high on the mast, usually where the shrouds are fixed, to a hook on the crew member's harness at approximately waist level. The position when extended on the trapeze is outside the hull, braced against it (or an extension of it outwards) with the soles of the feet, facing the masthead, and clipped on by a hook on the trapeze harness. This gives the crew member more leverage to keep the boat flat by allowing the crew member's centre of gravity to balance the force of the wind in the sails. An additional benefit is the ability to "walk" along the gunwale to balance the boat's trim fore and aft. This is necessary to prevent racing catamarans such as the Tornado from digging the bow into the water, also called pitchpoling, and causing a nosedive and often a spectacular capsize. Boats may have only one trapeze, such as the 420 and the 29er, where only the crew uses the trapeze. Dinghies, such as the International 14 and th ...

Keel
The keel is the bottom-most longitudinal structural element on a vessel. On some sailboats, it may have a hydrodynamic and counterbalancing purpose, as well. As the laying down of the keel is the initial step in the construction of a ship, in British and American shipbuilding traditions the construction is dated from this event. Etymology The word "keel" comes from Old English , Old Norse , = "ship" or "keel". It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work ''De Excidio et Conquestu Britanniae'', under the spelling ''cyulae'' (he was referring to the three ships that the Saxons first arrived in). is the Latin word for "keel" and is the origin of the term careen (to clean a keel and the hull in general, often by rolling the ship on its side). An example of this use is Careening Cove, a suburb of Sydney, Australia, where careening was carried out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiller
A tiller or till is a lever used to steer a vehicle. The mechanism is primarily used in watercraft, where it is attached to an outboard motor, rudder post or stock to provide leverage in the form of torque for the helmsman to turn the rudder. A tiller may also be used in vehicles outside of water, and was seen in early automobiles. On vessels, a tiller can be used by the helmsman directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel. Rapid or excessive movement of the tiller results in an increase in drag and will result in braking or slowing the boat. Description A tiller is a lever used to steer a vehicle. It provides leverage in the form of torque to turn the device that changes the direction of the vehicle, such as a rudder on a watercraft or the surface wheels on a wheeled vehicle. A tiller can be used by directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel; some kayaks wh ...

Transom (nautical)
A transom is the vertical reinforcement which strengthens the stern of a boat. This flat termination of the stern is typically above the waterline. The term was used as far back as Middle English in the 1300s, having come from Latin ''transversus'' (transverse) via Old French ''traversain'' (set crosswise). The stern of a boat is typically vertical. It can be raked such that there is an overhang above the water, as at the bow. A reverse transom is angled from the waterline forwards. Transoms can be used to support a rudder, outboard motor, or as a swimming and access platform.

Raked Stem
The stem is the most forward part of a boat or ship's bow and is an extension of the keel itself. It is often found on wooden boats or ships, but not exclusively. Description The stem is the curved edge stretching from the keel below, up to the gunwale of the boat. It is part of the physical structure of a wooden boat or ship that gives it strength at the critical section of the structure, bringing together the port and starboard side planks of the hull. Plumb and raked stem There are two styles of stems: ''plumb'' and ''raked''. When the stem comes up from the water, if it is perpendicular to the waterline it is "plumb". If it is inclined at an angle to the waterline it is "raked". (For example, "The hull is single decked and characterized by a plumb stem, full bows, straight keel, moderate deadrise, and an easy turn of bilge.") Stemhead Because the stem is very sturdy, the top end of it may have something attached, either ornamental or functional in nature. On small ...

Aluminum
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity towards ox ...

Fractional Rig
A fractional rig on a sailing vessel consists of a foresail, such as a jib or genoa sail, that does not reach all the way to the top of the mast. The forestay is a wire that secures the mast to the front of the boat. With a fractional rig, the forestay is attached between about 1/8 and 1/4 of the length of the mast lower down, rather than being attached to the top of the mast as in a masthead rig. The foresail (jib or genoa) is then rigged to this stay. The mast is farther forward on the boat than on a masthead rig and so it has a larger mainsail. Masthead rigs are most common on larger keelboats or cruisers. A fractional rig is typically used on sailing dinghies and racing oriented keelboats, such as the J/24. Fractional rigs were introduced on race boats in order to allow more controllability of the surface of the mainsail and also less drag when sailing upwind. According to one manufacturer, "a key to making fast boats easier to sail than slow boats is the 'fractional rig' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keelboat
A keelboat is a riverine cargo-capable working boat, or a small- to mid-sized recreational sailing yacht. The boats in the first category have shallow structural keels, and are nearly flat-bottomed and often used leeboards if forced in open water, while modern recreational keelboats have prominent fixed fin keels, and considerable draft. The two terms may draw from cognate words with different final meaning. A keep boat, keelboat, or keel-boat is a type of usually long, narrow cigar-shaped riverboat, or unsheltered water barge which is sometimes also called a poleboat—that is built about a slight keel and is designed as a boat built for the navigation of rivers, shallow lakes, and sometimes canals that were commonly used in America including use in great numbers by settlers making their way west in the century-plus of wide-open western American frontiers. They were also used extensively for transporting cargo to market, and for exploration and trading expeditions, for wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
