International Catamaran Challenge Trophy
The International Catamaran Challenge Trophy is the formal name for the match racing series between two catamarans familiarly known the Little Americas Cup. While a championship series sailed between C Class catamarans does still exist, it is no longer known as the Little America's Cup. Loosely modelled on the Americas Cup series for yachts, it started in 1961 after UK catamaran designer Rod Mcalpine-Downie became aware of a challenge from America that claimed they had "the fastest sailboat". Rod answered the challenge and simple rules were agreed. The challenge had to come from a recognized yacht club and consequently was taken up by John Fisk on behalf of the Chapman Sands Yacht Club of which he was Commodore and friend of Rod. The challenge was successful and the trophy went to the UK where it stayed for 8 years. The simple design rules were formalised, overall length of , beam of and total sail area of to be sailed by a two-man crew. These formed the basis of the rules for t ...

Americas Cup
The America's Cup, informally known as the Auld Mug, is a trophy awarded in the sailing (sport), sport of sailing. It is the oldest International sport, international competition still operating in any sport. America's Cup match racing, match races are held between two sailing yachts: one from the yacht club that currently holds the trophy (known as the defender) and the other from the yacht club that is challenging for the cup (the challenger). Matches are held several years apart on dates agreed between the defender and the challenger. There is no fixed schedule, but the races have generally been held every three to four years. The most recent America's Cup match took place in March 2021. The cup was originally known as the 'R.Y.S. £100 Cup', 1851 America's Cup, awarded in 1851 by the British Royal Yacht Squadron for a race around the Isle of Wight in the United Kingdom. The winning yacht was a schooner called ''America (yacht), America'', owned by a syndicate of members fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rod Macalpine-Downie
James Roderick Macalpine-Downie (9 May 1934 – 9 January 1986), known as Rod Macalpine-Downie, was an English multihull sailboat designer and sailor. Son of Lieutenant-Colonel Archibald James Macalpine-Downie (died 1958), M.B.E., Royal Tank Regiment, of a landed gentry family of Appin, he was a King's Scholar at Eton with a focus on biology, but seriously considered a career as a concert violinist. Macalpine-Downie and his wife, Shirley Agnes (née Reid), had two sons and a daughter. Design career After seeing a Shearwater catamaran while chicken farming in Scotland, Macalpine-Downie resolved to design a superior vessel, producing the Thai Mk4 catamaran. The Thai Mk4 was extremely successful, winning all six races of the 1962 European 'one of a kind' regatta, in addition to the first International Catamaran Challenge in 1963. Legacy Macalpine-Downie is said to have been the first to try both 'una rig' and wing masts. His two most famous designs were the high-speed ''Crossbow ...

Tornado (sailboat)
The Tornado is a double handed multihull class recognised as an International Class by the International Sailing Federation. It was used for the Catamaran discipline at the Sailing at the Summer Olympics, Olympic Games from 1976 to 2008. Design The boat was designed in 1967 by Rodney March from the Isle of Sheppey, England. At the IYRU Olympic Catamaran Trials for international status, where it defeated other catamarans. To increase its performance even further, the Tornado was modified in 2001, with a new sail plan which included a spinnaker and spinnaker boom, as well as an increased sail area of the existing sails. An additional Trapeze (sailing), trapeze was also added, and the jib was made self tacking. The Tornado is among the fastest double handed catamarans, with an ISAF Small Catamaran Handicap Rating System rating of 0.934 and a Portsmouth Yardstick, D-PN of 59.0. It is the fastest catamaran in the Royal Yachting Association, RYA Portsmouth Yardstick scheme, with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wing Mast
A wing is a type of fin that produces lift while moving through air or some other fluid. Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift. Lifting structures used in water include various foils, such as hydrofoils. Hydrodynamics is the governing science, rather than aerodynamics. Applications of underwater foils occur in hydroplanes, sailboats and submarines. Etymology and usage For many centuries, the word "wing", from the Old Norse ''vængr'', referred mainly to the foremost limbs of birds (in addition to the architectural aisle). But in recent centuries the word's meaning has exten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wingsail
A wingsail, twin-skin sail or double skin sail is a variable-camber aerodynamic structure that is fitted to a marine vessel in place of conventional sails. Wingsails are analogous to airplane wings, except that they are designed to provide lift on either side to accommodate being on either tack. Whereas wings adjust camber with flaps, wingsails adjust camber with a flexible or jointed structure (for hard wingsails). Wingsails are typically mounted on an unstayed spar—often made of carbon fiber for lightness and strength. The geometry of wingsails provides more lift, and a better lift-to-drag ratio, than traditional sails. Wingsails are more complex and expensive than conventional sails. Introduction Wingsails are of two basic constructions that create an airfoil, "soft" and "hard", both mounted on an unstayed rotating mast. Whereas hard wingsails are rigid structures that are stowed only upon removal from the boat, soft wingsails can be furled or stowed on board. L. Fra ...

AC45
The America's Cup World Series are match races and fleet regattas used as heats for the 2013 America's Cup and the 2017 America's Cup. The Yachts AC45 and AC45F The World Series uses AC45 catamarans, a one-design wingsail catamaran designed specifically for the event by Oracle Racing. The AC45 was conceived as a smaller version of the larger AC72 class rule which was used for the 2013 America's Cup. In 2015, the class was modified to AC45F which incorporated hydrofoiling capability for improved performance, with boats achieving peak speeds of 37kt. The AC45 has the following specifications: *design: Mike Drummond & Oracle Racing *builder: Core Builders Composites (NZ) & TP Cookson (NZ) *build: honeycomb core, carbonfiber sandwich *length: *beam: *weight: *maximum draught : *air draught : without extension, with extension *wing: wing element with three slotted flaps *extension: high, area *jib area: , provided by sail loft of team's choice (2011–2013 series), provide ...

AC72
The AC72 (America's Cup 72 class) is a class of wingsail catamarans built to a box rule, which governs the construction and operation of yachts competing in the 2013 Louis Vuitton and the America's Cup races. The class was subsequently replaced by the smaller AC50 class. Background Following the 2010 America's Cup, where the Golden Gate Yacht Club's '' USA 17'' trimaran defeated the catamaran ''Alinghi 5'', it was decided by the winners that the next America's Cup competition would be sailed in catamarans in the hope of making the sport more attractive to television audiences. At the same time a smaller sister class, the AC45, was developed to allow teams to practice and adjust to the new formula as well as create a greater exposure of sailing to the general public with the America's Cup World Series. Specifications The AC72 has the following maximum specifications: *overall length: *waterline length: *beam: *weight: *maximum draught: *crew: 11 Maximum Speed Using foils ...

National Maritime Museum Cornwall
The National Maritime Museum, Cornwall is located in a harbourside building at Falmouth in Cornwall, England. The building was designed by architect M. J. Long, following an architectural design competition managed by RIBA Competitions. The museum grew out of the FIMI (Falmouth International Maritime Initiative) partnership which was created in 1992 and was the result of collaboration between the National Maritime Museum, Greenwich and the former Cornwall Maritime Museum in Falmouth. It opened in February 2003. It is an independent charitable trust and, unlike other national museums, receives no direct government support. Its mission is to promote an understanding of boats and their place in people's lives, and of the maritime heritage of Cornwall. It does this by presenting the story of the sea, boats and the maritime history of Cornwall. It maintains the National Small Boats Register (NSBR). Boats The Museum manages the National Small Boat Collection, which came from the N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
