GC32
The GC32 is a class of hydrofoiling catamaran, 32 feet in length (9.75 meters) and constructed of carbon fibre, with a top speed of about . They are sailed in the GC32 Racing Tour, and have replaced the Extreme 40, Extreme 40's in the Extreme Sailing Series. History Conceived by Laurent Lenne, who was trained as a naval architect in Southampton, the GC32 was designed by Dr. Martin Fischer. Built from carbon fibre, the boat is manufactured in Dubai by Premier Composite Technologies and then marketed by Lenne's company, THE GREAT CUP BV. In 2013, the first version of the GC32 was built. In 2014, the second version of the Flying GC32 was ready by April 2014 and create the GC32Racing Tour in 2014. Laurent is nowadays mainly responsible for expanding the GC32 racing experience and helping new owners to join the GC32 community.

GC32 Racing Tour
GC32 Racing Tour is a southern European-centered sailing boat circuit for GC32 one design foiling catamarans. It attracts both private owner-driven teams and those that are commercially-backed. History The aim of the circuit is to provide the 'best foiling catamaran experience' for its participants. This includes visiting venues known to provide optimum wind conditions for foiling and race courses large enough to enable the boats to hit maximum speeds. The GC32 Racing Tour has several features in common with the 34th and 35th America's Cup in that it uses foiling catamarans and a similar race format which often includes reaching (rather than upwind) starts. The circuit comprises five events. At each event and for the overall championship, prizes are awarded for the overall winner as well as the top 'owner-driver'. GC32 Racing Tour events also include the Anonimo Speed Challenge in which teams try to sail the fastest over a course that comprises two reaching legs with a gybe i ...

Extreme Sailing Series
The Extreme Sailing Series (ESS) (formerly the iShares Cup) was an annual global racing series, organised by OC Sport, which ran from 2007 to 2018. The series started in 2007 with its main attraction being the stadium racing which puts the race course inside a stadium environment for the ease of spectators' viewing. Many of the sailors taking part in the series were around-the-world yachtsmen, Olympic medallists, America's Cup The America's Cup is a sailing competition and the oldest international competition still operating in any sport. America's Cup match races are held between two sailing yachts: one from the yacht club that currently holds the trophy (known ... sailors, World and European champions and even world record holders. The series was terminated in 2019 after the event became financially nonviable and OC Sport were unable to secure a management buy-out. Results Based on results from 2007 to 2018, Pete Greenhalgh (GBR) is the most successful sailor ... [...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 was created by Eric Walters. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...

Lake Garda
Lake Garda (, , or , ; ; ) is the largest lake in Italy. It is a popular holiday location in northern Italy, between Brescia and Milan to the west, and Verona and Venice to the east. The lake cuts into the edge of the Eastern Alps, Italian Alps, particularly the Alpine List of mountain groups in the Alpine Club classification of the Eastern Alps, sub-ranges of the Garda Mountains and the Brenta group, Brenta Group. Glaciers formed this alpine region at the end of the Last Glacial Period, last ice age. The lake and its shoreline are divided between the provinces of Province of Brescia, Brescia (to the south-west), Province of Verona, Verona (south-east) and Trentino (north). Etymology In Roman times the lake was known as ''Benacus'' and by some it was revered as god Benacus, the personification of the lake, sometimes associated with the cult of Neptune (mythology), Neptune. Today it is better known as Lake Garda, a toponym of Germanic origin attested since the Middle Ages and de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Sailing
World Sailing is the international sports governing body for sailing (sport), sailing; it is recognized by the International Olympic Committee (IOC) 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 chang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wingsail
A wingsail, twin-skin sail or double skin sail is a variable-Camber (aerodynamics), camber aerodynamic structure that is fitted to a marine vessel in place of conventional sails. Wingsails are analogous to Wing, airplane wings, except that they are designed to provide lift on either side to accommodate being on either Tack (sailing), tack. Whereas wings adjust camber with Flap (aeronautics), 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-reinforced polymer, 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 s ...

34th America's Cup
The 34th America's Cup was a series of yacht races held in San Francisco Bay in September 2013. The series was contested between the defender Oracle Team USA team representing the Golden Gate Yacht Club, and the challenger Emirates Team New Zealand representing the Royal New Zealand Yacht Squadron. The format was changed radically to a best of 17, and Oracle Team USA defended the America's Cup by a score of 9 to 8 after Team New Zealand had built an 8 to 1 lead. Team New Zealand won the right to challenge for the Cup by previously winning the 2013 Louis Vuitton Cup. The 34th America's Cup's race schedule was the longest ever, in terms of number of days and number of races, and the first since the 25th America's Cup to feature both teams in a match point situation. Background The Golden Gate Yacht Club defeated Société Nautique de Genève in the 2010 America's Cup to become the Defenders of the 2013 America's Cup. The first Challenger of Record for the 34th Cup was Club N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 f ...

Daggerboard
A daggerboard is a retractable centreboard used by various sailing craft. While other types of centreboard may pivot to retract, a daggerboard slides in a casing. The shape of the daggerboard converts the forward motion into a windward lift, countering the leeward push of the sail. The theoretical centre of lateral resistance is on the trailing edge of the daggerboard. General A daggerboard is a removable vertical keel that is inserted through a "trunk" in the center of a vessel's hull, usually amidships. Daggerboards are usually found in small sailing craft such as day sailers, which are easily handled by a single person. Daggerboards are not usually ballasted but are locked in place by a clip or pin. Unlike a centreboard, which can be set at different angles to the hull of the boat, daggerboards are generally limited to a single perpendicular position relative to the hull. If a daggerboard is located off center, it is called a leeboard or a bilgeboard. The characteristic whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium (usually air or water). On an airplane, the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or afterend. Often rudders are shaped to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics. H ...
