Surface Water Sports
The following is a list of surface water sports. These are sports which are performed atop a body of water. Boat racing Motorized racing * Hydroplane racing * Bathtub racing Rowing * Canoeing * Kayaking * Sweep rowing * Sculling * Dragon boat racing Sailing * Yacht racing * Hydrofoil sailing. This recent development in the high-speed sailing arena has evolved most in the International Moth class of racing dinghy. These boats have a T-shaped rudder and centreboard that generates sufficient lift to clear the hull from the water. When this happens wetted surface area drops radically and the boats accelerate up to 1.2 to 1.5 times the speed of the prevailing wind. These boats are very light (all up weight is less than 40 kg) and very fast, They hydrofoil in as little as of breeze ("sit on the deck breeze" for most dinghy classes). The top recorded speed is about 50 km/hour, and speeds of 40 km/hour are common in the class. All types of propulsion * Dinghy racin ...

Water Skiing
Water skiing (also waterskiing or water-skiing) is a surface water sport in which an individual is pulled behind a boat or a cable ski installation over a body of water, skimming the surface on one or two skis. The sport requires sufficient area on a stretch of water, one or two skis, a tow boat with tow rope, two or three people (depending on local boating laws), and a personal flotation device. In addition, the skier must have adequate upper and lower body strength, muscular endurance, and good balance. There are water ski participants around the world, in Asia and Australia, Europe, Africa, and the Americas. In the United States alone, there are approximately 11 million water skiers and over 900 sanctioned water ski competitions every year. Australia boasts 1.3 million water skiers. There are many options for recreational or competitive water skiers. These include speed skiing, trick skiing, show skiing, slaloming, jumping, barefoot skiing and wakeski. Similar, related ...

Wakesurfing
Wakesurfing is a water sport in which a person surfs the wake that is created by the boat. Wakesurfers ride without rope, they use it only to be pulled by the boat from the water. After getting up on the wake, typically by use of a tow rope, the wakesurfers will drop the rope, and ride the steep face below the wave's peak in a fashion reminiscent of surfing. Wakesurfers use special boards, designed specifically for this sport. History The origins of wakesurfing are a subject of contention, as various individuals and companies lay claim to its inception. Some assertions trace the roots of boat-surfing or wake-surfing back as far as the 1920s, but there is a lack of credible evidence to support these claims. Visual records and written media from the 1950s and 1960s depict surfers actively riding surfboards behind motorboats in ocean settings. During the mid-1960s, numerous surfboard manufacturers began asserting their involvement in crafting boards specifically designed for ridi ...

Wakeskating
Wakeskating is a water sport and an adaptation of wakeboarding that employs a similar design of board manufactured from maple or fibreglass. Unlike wakeboarding, the rider is not bound to the board in any way, similar to the skateboard, from which the name derives. Design Fins are constructed of plastic, fiberglass or aluminum. Shorter fins must be deeper to get the same amount of tracking. A shallower fin does not track as well as a deeper one. But a deeper fin has more drag in the water, and does not release from the water as fast. Wakeskating shoes are designed with quick drying materials and drainage channels. The drainage channels are a system of holes in the sole and channels through the midsole. Most wakeskate boards are made with grip tape on the upper side like skateboards. The grip tape is like sandpaper; it helps the rider to stay on the board and provides good traction, and is the main reason why rider wears shoes. Some boards are made with a foam instead of grip-ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (fluid)
In fluid mechanics, displacement occurs when an object is largely immersed in a fluid, pushing it out of the way and taking its place. The volume of the fluid displaced can then be measured, and from this, the volume of the immersed object can be deduced: the volume of the immersed object will be exactly equal to the volume of the displaced fluid. An object immersed in a liquid displaces an amount of fluid equal to the object's volume. Thus, buoyancy is expressed through Archimedes' principle, which states that the weight of the object is reduced by its volume multiplied by the density Density (volumetric mass density or specific mass) is the ratio of a substance's mass to its volume. The symbol most often used for density is ''ρ'' (the lower case Greek letter rho), although the Latin letter ''D'' (or ''d'') can also be u ... of the fluid. If the weight of the object is less than this displaced quantity, the object floats; if more, it sinks. The amount of fluid displace ...

Wakeboard Boat
Wakeboard boats also known as wakeboats, surfboats or tow boats are designed to create a large, specially shaped wake, for a wakeboarder to jump the wakes from side to side doing aerial tricks. They developed from the Runabout type. Boat types Generally speaking, wakeboard specific boats are V-drive boats. This means they are an inboard boat with the engine placed backwards in the rear of the boat. This is done to keep more weight in the back of the boat and make the wake larger. Some wakeboard specific boat models are direct drive boats where the engine is in the middle of the boat. Most wakeboard boats will have several features that help to create large wakes. These include ballast, hydrofoil, and hull technology. Ballast is a simple term for weight. When wakeboard boats have ballast tanks, it means that they have room for extra weight to weigh the boat down for larger wakes. For example. If the rider is surfing on the starboard side of the stern. Then you want to activ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wake (physics)
In fluid dynamics, a wake may either be: * the region of recirculating flow immediately behind a moving or stationary blunt body, caused by viscosity, which may be accompanied by flow separation and turbulence, or * the wave pattern on the water surface downstream of an object in a flow, or produced by a moving object (e.g. a ship), caused by density differences of the fluids above and below the free surface and gravity (or surface tension). Viscosity The wake is the region of disturbed flow (often turbulent) downstream of a solid body moving through a fluid, caused by the flow of the fluid around the body. For a blunt body in subsonic external flow, for example the Apollo or Orion capsules during descent and landing, the wake is massively separated and behind the body is a reverse flow region where the flow is moving toward the body. This phenomenon is often observed in wind tunnel testing of aircraft, and is especially important when parachute systems are involved, becaus ...

Wakeboarding
Wakeboarding is a water sport in which the rider, standing on a wakeboard (a board with foot bindings), is towed behind a motorboat across its wake and especially up off the crest in order to perform aerial maneuvers. A hallmark of wakeboarding is the attempted performance of midair tricks. Wakeboarding was developed from a combination of water skiing, snowboarding and surfing techniques. The rider is usually towed by a rope behind a boat, but can also be towed by cable systems and winches, and be pulled by other motorized vehicles like personal watercraft, cars, trucks, and all-terrain vehicles. The gear and wakeboard boat used are often personalized to each rider's liking. Though natural watercourses such as rivers, lakes and areas of open water are generally used in wakeboarding, it is possible to wakeboard in unconventional locations, such as flooded roads and car parks, using a car as the towing vehicle. Wakeboarding is done for pleasure and competition, ranging from frees ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sit-down Hydrofoil
The sit-down hydrofoil, first developed in the late 1980s, is a variation on water skiing, a popular water sport. When towed at speed, by a powerful boat or some other device, the board of the hydrofoil 'flies' above the water surface and generally avoids contact with it, so the ride is largely unaffected by the wake or chop of the water and is relatively smooth. The air board is a modified hydrofoil where the skier stands up. History Hydrofoils date back to the early 1900s, however, they were not part of a recreational sport. While the first hydrofoil boat was created in 1906 by Italian inventor Enrico Forlanini, the first waterski hydrofoil was invented in the early 1960s by Walter Woodward, an aeronautical engineer, with two skis attached to a bi-wing hydrofoil. In 1972, Mike Murphy and Bob Woolley added a bi-wing hydrofoil to a surfing kneeboard, then reduced the bi-wing to a single wing. Murphy and Woolley then applied the concept to sit-down hydrofoil, with Woolley riding th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kneeboarding (towsport)
Kneeboarding is an aquatic sport where the participant is towed on a buoyant, convex, and hydrodynamically shaped board at a planing speed, most often behind a motorboat. Kneeboarding on a surf style board with fin(s) is also done in waves at the beach. In the usual configuration of a tow-sport kneeboard, riders kneel on their heels on the board, and secure themselves to the deck with an adjustable Velcro Velcro IP Holdings LLC, trading as Velcro Companies and commonly referred to as Velcro (pronounced ), is a British privately held company, founded by Swiss electrical engineer George de Mestral in the 1950s. It is the original manufacturer of ho ... strap over their thighs. Most water ski kneeboards do not have fins to allow for easier surface spins. As in wakeboarding or water skiing, the rider hangs onto a tow-rope. The advantages of kneeboarding versus other tow-sports seems to be an easier learning curve and a sense of being closer to the water when falls occur must ...
