Sailing Hydrofoil
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 sailbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oracle Team USA In The 2013 America's Cup
An oracle is a person or agency considered to provide wise and insightful counsel or prophetic predictions, most notably including precognition of the future, inspired by deities. As such, it is a form of divination. Description The word ''oracle'' comes from the Latin verb ''ōrāre'', "to speak" and properly refers to the priest or priestess uttering the prediction. In extended use, ''oracle'' may also refer to the ''site of the oracle'', and to the oracular utterances themselves, called ''khrēsmē'' 'tresme' (χρησμοί) in Greek. Oracles were thought to be portals through which the gods spoke directly to people. In this sense, they were different from seers (''manteis'', μάντεις) who interpreted signs sent by the gods through bird signs, animal entrails, and other various methods.Flower, Michael Attyah. ''The Seer in Ancient Greece.'' Berkeley: University of California Press, 2008. The most important oracles of Greek antiquity were Pythia (priestess to Apollo ...

Carbon-fiber
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other additi ...

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.

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 ...

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.

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 ().

Optimist (dinghy)
The Optimist is a small, single-handed sailing dinghy intended for use by young people up to the age of 15. The Optimist is one of the two most popular sailing dinghies in the world, with over 150,000 boats officially registered with the class and many more built but never registered. It is sailed in over 120 countries and it is one of only two sailboats as an International Class by World Sailing exclusively for sailors under 16. Origin The Optimist was designed in 1947 by American Clark Mills at the request of the Clearwater Florida Optimist service club following a proposal by Major Clifford McKay to offer low-cost sailing for young people. The Optimist Club ran a soap box derby, but wanted more than a single-day event. Thus they were looking for a low-cost equivalent for sailing. He designed a simple pram that could be built from two 4' x 8' sheets of plywood, and donated the plan to the Optimists. The design was slightly modified and introduced to Europe by Axel Damg ...

Laser (dinghy)
The Laser is a class of Single-handed sailing, single-handed, one-design dinghy sailing, sailing dinghies using a common hull design with three interchangeable rigs of different sail areas, appropriate to a given combination of wind strength and crew weight. Bruce Kirby (yachts), Bruce Kirby designed the Laser in 1970 with an emphasis on simplicity and performance. The Laser is a widely produced class of dinghies. As of 2018, there were more than 215,000 boats worldwide. It is an international class with sailors in 120 countries, and an Olympic class since 1996. Its wide acceptance is attributable to its robust construction, simple rig and ease of sailing that offer competitive racing due to tight class association controls which eliminate differences in hull, sails, and equipment. The International Laser Class Association (ILCA) defines the specifications and competition rules for the boat, which is officially referred to as the ILCA Dinghy, due to a trademark dispute.

Skiff
A skiff is any of a variety of essentially unrelated styles of small boats. Traditionally, these are coastal craft or river craft used for leisure, as a utility craft, and for fishing, and have a one-person or small crew. Sailing skiffs have developed into high performance competitive classes. Many of today's skiff classes are based in Australia and New Zealand in the form of , , and skiffs. The 29er, 49er, SKUD and Musto Skiff are all considered to have developed from the skiff concept, all of which are sailed internationally. The term skiff is also used for a racing shell called single scull for competitive rowing. Etymology The word is related to ''ship'' and has a complicated etymology: "skiff" comes from the Middle English ''skif'', which derives from the Old French ''esquif'', which in turn derives from the Old Italian ''schifo'', which is itself of Germanic origin (German ''Schiff''). "Ship" comes from the Old English "scip", which has the same Germanic predecessor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
