Foilboard
A foilboard or hydrofoil board is a surfboard with a hydrofoil that extends below the board into the water. This design causes the board to leave the surface of the water at various speeds. Background Laird Hamilton, a prominent figure in the invention of big wave tow-in surfing, later discovered the foilboard's capability to harness swell energy with the use of a jet ski, pulling the rider into a wave. The original stand-up design, used with the use of snow board boots, allowed the rider to glide with the moving wave by harnessing the kinetic energy with the underwater swell. Hydrofoil kiteboards allow the rider to achieve the same result with the use of a kite. The hydrofoil minimizes the effects of choppy or rough conditions. Due to the hydrofoil's underwater characteristics, the rider can angle higher into the wind than on traditional kiteboards which ride on the surface of the water. Rush Randle, a noted acrobatic surfer and big wave windsurfer, is credited with being the f ... [...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] |
Wing Foiling
Wing foiling or wing surfing or winging is a wind propelled water sport that developed from kitesurfing, windsurfing and surfing. The sailor, standing on a board, holds directly onto a wing. It generates both upward force and sideways propulsion and thus moves the board across the water. The recent development of foilboards, which plane very early on a hydrofoil fin and thereby lift off the water producing low friction, represent the ideal complementary hydrodynamic platform for wings. This young sport is poised to become wildly popular. History Precursors The history of wing foiling begins with the invention of wing surfing dating back to 1981, when aeronautical engineer Jim Drake, the inventor of windsurfing, and Uli Stanciu, European windsurfing pioneer, together invented the first wing. Their patented concept was based on the symmetrical shape of the flying fish. Unlike windsurfing, their wing was hand held and not fixed to the board via a mast. About the same time ...

Laird Hamilton
Laird John Hamilton (born March 2, 1964) is an American big-wave surfer, co-inventor of tow-in surfing, and an occasional fashion and action-sports model and actor. He is married to Gabrielle Reece, a professional volleyball player, television personality, and model. Early life Laird was born Laird John Zerfas in San Francisco on March 2, 1964, in an experimental salt-water sphere at UCSF Medical Center designed to ease the mother's labor. His father, L. G. Zerfas, left the family before his first birthday. While he was an infant, Laird and his mother, Joann (née Zyirek), moved to Hawaii. In 1967, while still a young boy living on Oahu, Laird met with 1960s surfer William Stuart "Bill" Hamilton, a bachelor at the time, on Pūpūkea beach on the North Shore. Bill Hamilton was a surfboard shaper and glasser on Oahu in the 1960s and 1970s and owned a small business handmaking custom, high-performance surfboards for the Oahu North Shore big wave riders of the era. The two became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kiteboarding
Kiteboarding or kitesurfing is a sport that involves using wind power with a large power kite to pull a rider across a water, land, or snow surface. It combines aspects of paragliding, surfing, windsurfing, skateboarding, snowboarding, and wakeboarding. Kiteboarding is among the less expensive and the more convenient sailing sports. After some concepts emerged in the late 1970s and early 1980s and some designs were successfully tested, the sport received a wider audience in the late 1990s and became mainstream at the turn of the century. It has freestyle, wave-riding, and racing competitions. The sport held the speed sailing record, reaching before being eclipsed by the Vestas Sailrocket. Worldwide, there are 1.5 million kitesurfers, while the industry sells around 100,000 to 150,000 kites per year. Most power kites are leading edge inflatable kites or foil kites attached by about of flying lines to a control bar and a harness. The kitesurfer rides on either a bidire ...

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.

Surfboard
A surfboard is a narrow plank used in surfing. Surfboards are relatively light, but are strong enough to support an individual standing on them while riding an ocean wave. They were invented in ancient Hawaii, where they were known as ''papa he'e nalu'' in the Hawaiian language, and were usually made of wood from local trees, such as koa. They were often over in length and extremely heavy. Major advances over the years include the addition of one or more fins (skegs) on the bottom rear of the board to improve directional stability, and numerous improvements in materials and shape. Modern surfboards are made of polyurethane or polystyrene foam covered with layers of fiberglass cloth, and polyester or epoxy resin. The result is a light and strong surfboard that is buoyant and maneuverable. Recent developments in surfboard technology have included the use of carbon fiber and kevlar composites, as well as experimentation in biodegradable and ecologically friendly resins made from ...
