Foiling
A sailing hydrofoil, hydrofoil sailboat, or hydrosail is a sailboat with wing-like foils mounted under the hull. As the craft increases its speed the hydrofoils lift the hull up and out of the water, greatly reducing wetted area, resulting in decreased drag and increased speed. A sailing hydrofoil can achieve speeds exceeding double and in some cases triple the wind speed. Both monohull and multihull sailboats can be retrofitted with hydrofoils, although greater stability can be achieved by using the wider planform of a catamaran or trimaran. Typical configurations Some multihulls use three foils; two main forward foils provide lift so that the boat "flies" while a horizontal foil on the rudder is trimmed to drive and control altitude. On catamarans, a single main foil can be attached between the hulls just in front of the center of gravity and at 2 degrees of incidence, spanning the tunnel with supporting struts. Hydrofoil catamarans are also called foilcats. Multihull sailboa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrofoil
A hydrofoil is a lifting surface, or foil, that operates in water. They are similar in appearance and purpose to aerofoils used by aeroplanes. Boats that use hydrofoil technology are also simply termed hydrofoils. As a hydrofoil craft gains speed, the hydrofoils lift the boat's hull out of the water, decreasing drag and allowing greater speeds. Description The hydrofoil usually consists of a winglike structure mounted on struts below the hull, or across the keels of a catamaran in a variety of boats (see illustration). As a hydrofoil-equipped watercraft increases in speed, the hydrofoil elements below the hull(s) develop enough lift to raise the hull out of the water, which greatly reduces hull drag. This provides a corresponding increase in speed and fuel efficiency. Wider adoption of hydrofoils is prevented by the increased complexity of building and maintaining them. Hydrofoils are generally prohibitively more expensive than conventional watercraft above a certain disp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2021 America's Cup
The 36th America's Cup in March 2021 was the latest staging of the America's Cup yacht race. It was contested on the inner Hauraki Gulf off Auckland, New Zealand, between the Royal New Zealand Yacht Squadron and Circolo della Vela Sicilia of Italy. The Royal New Zealand Yacht Squadron's boat was '' Te Rehutai'' owned and sailed by the Emirates Team New Zealand syndicate. Circolo della Vela Sicilia's boat was ''Luna Rossa'', owned and sailed by the Luna Rossa Prada Pirelli syndicate. Both boats are AC75 class high-performance foiling monohulls, a class designed specifically for this competition. The Cup was won by Team New Zealand, 7–3. The Royal New Zealand Yacht Squadron was the Defending Club, having won the preceding 35th America's Cup in 2017, and was therefore responsible for organizing and hosting this event. The Challenging Club was Circolo della Vela Sicilia, whose team won the selection series – the 2021 Prada Cup – and was also the Challenger of Record, h ...

Catamaran
A Formula 16 beachable catamaran Powered catamaran passenger ferry at Salem, Massachusetts, United States A catamaran () (informally, a "cat") is a multi-hulled watercraft featuring two parallel hulls of equal size. It is a geometry-stabilized craft, deriving its stability from its wide beam, rather than from a ballasted keel as with a monohull boat. Catamarans typically have less hull volume, smaller displacement, and shallower draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes. Catamarans were invented by the Austronesian peoples which enabled their expansion to the islands of the Indian and Pacific Oceans. Catamarans range in size from small sailing or rowing ve ...

Moth (dinghy)
The Moth is a small development class of sailing dinghy. Originally a small, fast home-built sailing boat designed to plane, since 2000 it has become an expensive and largely commercially-produced boat designed to hydroplane on foils though many are still built at home, typically at much lower cost. The pre-hydrofoil design Moths are still sailed and raced, but are far slower than their foiled counterparts. Types There have been several types of Moth since the first use of the class name in the 1920s: *The Classic Moth, a traditional dinghy with tighter design restrictions *The British Moth, designed in 1932 and revived in 2004 *The Restricted Moth of the 1960s and 70s, with few design restrictions to allow for class development (International Moth in Australia and New Zealand) *The Europa Moth, which became the Olympic Europe dinghy *The New Zealand Mark 2 scow Moth, abundant in the 1970s *The International Moth, a fast sailing hydrofoil dinghy with few design restrictions ...

World Sailing
World Sailing (WS) is the world governing body for the sport of sailing recognized by the International Olympic Committee and the International Paralympic Committee (IPC). History The creation of the International Yacht Racing Union (IYRU) began in 1904, when Major Brooke Heckstall-Smith AINA, then Secretary of the Yacht Racing Association (now the Royal Yachting Association) wrote to the Yacht Club de France, pointing out the desirability of holding a conference for the purpose of devising an International Rule of Measurement for Racing Yachts acceptable to all European countries. As a result, an International Conference of Yacht Measurement was held in London in January and June 1906, at which the Metre Rule was developed. This group went on to adopt a formal Constitution after a meeting at the Yacht Club de France in Paris on 14 October 1907 which is seen as the formation date of the International Yacht Racing Union. On 5 August 1996, the IYRU changed its name to the Interna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IQFoil
iQFoil is a windsurfing class selected by World Sailing to replace the RS:X for the 2024 Summer Olympics. The discipline has similarities to Formula Windsurfing, however a notable difference is that sailors only use one sail. The sail size is 9m2 for the men and 8m2 for the women. The rider has a choice between using a hydrofoil or a conventional 68 cm fin. See also * iQFoil World Championships * Windfoiling Windfoiling (or foil windsurfing) is a surface water sport that is the hydrofoiling evolution of windsurfing, as well as typical sailing boats and sailing hydrofoils.

AC75
The AC75 (America's Cup 75) is a racing yacht used in the 2021 America's Cup match and planned to be used for the 37th America's Cup and 38th America's Cup matches. The monohulls feature wing-like sailing hydrofoils mounted under the hull, a soft wingsail, and no keel. The rule Following the 2017 America's Cup, winners Royal New Zealand Yacht Squadron accepted a notice of challenge from Circolo della Vela Sicilia stipulating a monohull would be used in 2021. Conceptual graphics of a monohull with soft sails and topside canting hydrofoils were released on 21 November 2017, and the first draft of the class rule was published by the defender and the challenger of record on 29 March 2018. The return to monohulls with soft sails after three America's Cups on multihulls with wingsails is reminiscent of earlier America's Cup classes and seaworthy traditions, but the rule included hydrofoils to attract high performance crews and large TV audiences. Under the protocol, each compet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sydney
Sydney ( ) is the capital city of the state of New South Wales, and the most populous city in both Australia and Oceania. Located on Australia's east coast, the metropolis surrounds Sydney Harbour and extends about towards the Blue Mountains to the west, Hawkesbury to the north, the Royal National Park to the south and Macarthur to the south-west. Sydney is made up of 658 suburbs, spread across 33 local government areas. Residents of the city are known as "Sydneysiders".

Centerboard
A centreboard or centerboard (US) is a retractable hull appendage which pivots out of a slot in the hull of a sailboat, known as a ''centreboard trunk'' (UK) or ''centerboard case'' (US). The retractability allows the centreboard to be raised to operate in shallow waters, to move the centre of lateral resistance (offsetting changes to the sailplan that move the centre of effort aft), to reduce drag when the full area of the centreboard is not needed, or when removing the boat from the water, as when trailering. A centreboard which consists of solely a pivoting metal plate is called a centerplate. A daggerboard is similar but slides vertically rather than pivoting. The analog in a scow is a bilgeboard: these are fitted in pairs and used one at a time. General History Lt. John Schank (c. 1740 – 6 February 1823) was an officer of the British Royal Navy and is credited with the invention of the centerboard. Schank, however, gave credit for the idea to British Brigadier General ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
