Canting Keel
A canting keel is a form of sailing ballast, suspended from a rigid canting strut beneath the boat, which can be swung to windward of a boat under sail, in order to counteract the heeling force of the sail. The canting keel must be able to pivot to either port or starboard, depending on the current tack. Purpose and history The traditional yacht keel performs four functions: * the development of lateral water force to resist lateral aerodynamic force from sails and superstructure, * the physical housing of ballast load as low as possible, * roll-damping to resist energy inputs from waves and disturbed water, and * a contribution to directional stability. The traditional fin keel, pointing straight down from the boat, provides no righting moment when the boat is level. The heeling force of the wind on the sails is therefore not counteracted until the boat has heeled over by a certain amount, moving the fixed keel to windward of the centerline. The purpose of the canting keel is to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volvo Ocean 65
The Volvo Ocean 65 is a class of monohull racing yachts. It is the successor to the Volvo Open 70 yacht used in past editions of the Volvo Ocean Race. It was announced at a conference in Lorient, France, during a stopover in the 2011–12 Volvo Ocean Race. The yacht was used for the 2014–2015 and the 2017–2018 editions and is planned to be used for the 2023 edition. The 2014–2015 Volvo Ocean Race was the first one-design event. Design The yacht was designed, by Farr Yacht Design, to be a cheaper and safer alternative to the expensive and fragile Volvo Open 70. After many safety concerns in the 2011–12 Volvo Ocean Race, many began doubting the safety of the Volvo Open 70, due to many designers opting for fast designs while failing to meet safety requirements. Former Volvo Ocean Race CEO, and four time competitor Knut Frostad hinted at a new boat design to address the current safety concerns in a statement he made during a press conference on April 4, 2012 stating: "It' ...

Alinghi
Alinghi, or Alinghi Red Bull Racing because of the sports marketing branding by Red Bull, is the syndicate set up by Ernesto Bertarelli, racing under the colors of the Société Nautique de Genève, to challenge for the America's Cup, as well as other competitions. Bertarelli had raced several smaller yachts named ''Alinghi'' previously, but 2003 was his first attempt at the America's Cup. Alinghi challenged for and won the 2003 America's Cup in Auckland New Zealand and successfully defended it at the 2007 America's Cup in Valencia, Spain. Alinghi lost the America's Cup to the Golden Gate Yacht Club and their team BMW Oracle Racing in a Deed of Gift match in Valencia, Spain in February 2010. For the 2003 event, Team New Zealand as the holder of the America's Cup, in consultation with Prada, the Challenger of Record, removed the nationality rule that stipulated that all of the crew members must be nationals of the challenging syndicate. Alinghi took full advantage of this rule ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International America's Cup Class
The International Americas Cup Class is a class of racing yacht that was developed for the America's Cup between 1992 and 2007. These yachts, while not identical, were all designed to the same formula to offer designers the freedom to experiment whilst keeping the boats sufficiently comparable to race in real time. The class was established for the 1992 America's Cup because of perceived shortcomings of the 12-metre class, which had been used in the America's Cup since 1958. In addition to the America's Cup, IACC yachts were raced in other regattas, including the IACC worlds. IACC Sail numbers IACC sail numbers were issued according to the date when the ACM measurement committee decided that the hull has reached a certain stage of completion. The number came in two parts: the flag state (represented by a three letter prefix) and the hull number. The country code changed as the hull was transferred from flag state to flag state. Only one boat had a sail number issued twice as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mike Golding
Mike Golding (born 27 August 1960) is an English yachtsman, born in Great Yarmouth and educated at Reading Blue Coat School. He is one of the few yachtsmen to have raced round the world non stop in both directions. He held the solo record for sailing round the world westabout (the most challenging direction for circumnavigation) between 1994 and 2000. Golding, who was named president of the Little Ship Club in 2017 and is a member of Royal Southampton Yacht Club, is the eponymous co founder of the commercial company Mike Golding Yacht Racing Ltd. His partner in this venture was Jorgen Philip-Sorensen (d.2010). Golding led the team ''Group 4'' to second place in the British Steel Challenge in 1992–3. He did one better in the next edition the BT Global Challenge 1996–7, taking first place with a new team of amateur sailors, again onboard ''Group 4''. Golding came seventh in the 2000–2001 Vendée Globe solo non stop round the world race having lost seven days to the disma ...

Southern Ocean
The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica. With a size of , it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian oceans but larger than the Arctic Ocean. Over the past 30 years, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem. By way of his voyages in the 1770s, James Cook proved that waters encompassed the southern latitudes of the globe. Since then, geographers have disagreed on the Southern Ocean's northern boundary or even existence, considering the waters as various parts of the Pacific, Atlantic, and Indian oceans, instead. However, according to Commodore John Leech of the International Hydrographic Organization (IHO), recent oceanographic research has discovered the importance of Southern ...

Velux 5 Oceans Race
The Velux 5 Oceans Race was a round-the-world single-handed yacht race, sailed in stages, managed by Clipper Ventures since 2000. Its most recent name comes from its main sponsor Velux. Originally known as the BOC Challenge, for the title sponsor BOC, the first edition was in 1982. In the late 1990s the race was renamed the Around Alone. After attracting just five entries in the 2010-11 race, the event has not been held since. Overview The race was established in 1982 as the ''BOC Challenge'', with main sponsorship from BOC. The race was inspired by the ''Golden Globe Race'', which was the first single-handed round-the-world yacht race. Although the ''Golden Globe'' was a non-stop race, the ''BOC Challenge'' concept was for a single-handed round-the-world race, to be run in stages (in contrast to the ''Vendée Globe'', which is non-stop). As the longest single-handed event in the world, it was regarded as one of sailing's ultimate challenges. The race was run every four year ...

Beagle Channel
Beagle Channel (; Yahgan: ''Onašaga'') is a strait in the Tierra del Fuego Archipelago, on the extreme southern tip of South America between Chile and Argentina. The channel separates the larger main island of Isla Grande de Tierra del Fuego from various smaller islands including the islands of Picton, Lennox and Nueva; Navarino; Hoste; Londonderry; and Stewart. The channel's eastern area forms part of the border between Chile and Argentina and the western area is entirely within Chile. The Beagle Channel, the Straits of Magellan to the north, and the open-ocean Drake Passage to the south are the three navigable passages around South America between the Pacific and Atlantic Oceans. Most commercial shipping uses the open-ocean Drake Passage. The Beagle Channel is about long and wide at its narrowest point. It extends from Nueva Island in the east to Darwin Sound and Cook Bay in the Pacific Ocean in the west. Some from its western end, it divides into two branches, north ...

Ushuaia
Ushuaia ( , ) is the capital of Tierra del Fuego, Antártida e Islas del Atlántico Sur Province, Argentina. With a population of nearly 75,000 and a location below the 54th parallel south latitude, Ushuaia claims the title of world's southernmost city. A much smaller municipality of less than 3,000 people, Puerto Williams in Chile, is nearer to the 55th parallel south, at a latitude of 54°56' S compared to Ushuaia at 54°48' S. Ushuaia is located in a wide bay on the southern coast of Isla Grande de Tierra del Fuego, bounded on the north by the Martial mountain range and on the south by the Beagle Channel. It is the only municipality in the Department of Ushuaia, which has an area of . It was founded on October 12, 1884, by Augusto Lasserre and is located on the shores of the Beagle Channel surrounded by the mountain range of the Martial Glacier, in the Bay of Ushuaia. Besides being an administrative center, it is a light industrial port and tourist hub. Ushuaia is located ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Horn
Cape Horn ( es, Cabo de Hornos, ) is the southernmost headland of the Tierra del Fuego archipelago of southern Chile, and is located on the small Hornos Island. Although not the most southerly point of South America (which are the Diego Ramírez Islands), Cape Horn marks the northern boundary of the Drake Passage and marks where the Atlantic and Pacific Oceans meet. Cape Horn was identified by mariners and first rounded in 1616 by the Dutchman Willem Schouten and Jacob Le Maire, who named it after the city of Hoorn in the Netherlands. For decades, Cape Horn was a major milestone on the clipper route, by which sailing ships carried trade around the world. The waters around Cape Horn are particularly hazardous, owing to strong winds, large waves, strong currents and icebergs. The need for boats and ships to round Cape Horn was greatly reduced by the opening of the Panama Canal in August 1914. Sailing around Cape Horn is still widely regarded as one of the major challenges in y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Knot (unit)
The knot () is a unit of speed equal to one nautical mile per hour, exactly (approximately or ). The ISO standard symbol for the knot is kn. The same symbol is preferred by the Institute of Electrical and Electronics Engineers (IEEE), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization (ICAO). The knot is a non- SI unit. The knot is used in meteorology, and in maritime and air navigation. A vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour. Definitions ;1 international knot = :1 nautical mile per hour (by definition), : (exactly), : (approximately), : (approximately), : (approximately) : (approximately). The length of the internationally agreed nautical mile is . The US adopted the international definition in 1954, having previously used the US nautical mile (). The UK adopted the international nautical mile definition in 1970, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
