Powerboating
Power boating describes activities performed in a motorized boat. Generally, a power boat has a high power-to-weight ratio and a hull design that allows for easy planing, which allows for higher speed and improved handling. Also, the shape of the actual boat is usually very streamlined, which minimizes air resistance and drag, therefore increasing speed. Power boats are used in yachting, waterskiing and wakeboarding. Powerboating is generally considered to have begun in 1863 when Frenchman Jean Lenoir used a petrol engine in the small boat. The first major race took place in 1903 across the English Channel and the sport appeared as an event in the 1908 Olympics.

Motorboat Racing
Boat racing is a sport in which boats, or other types of watercraft, race on water. Boat racing powered by oars is recorded as having occurred in ancient Egypt, and it is likely that people have engaged in races involving boats and other water-borne craft for as long as such watercraft have existed. A regatta is a series of boat races. The term comes from the Venetian language, with ''regata'' meaning "contest" and typically describes racing events of rowed or sailed water craft, although some powerboat race series are also called regattas. A regatta often includes social and promotional activities which surround the racing event, and except in the case of boat type (or "class") championships, is usually named for the town or venue where the event takes place. Although regattas are typically amateur competitions, they are usually formally structured events, with comprehensive rules describing the schedule and procedures of the event. Regattas may be organized as champions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorboat
A motorboat, speedboat or powerboat is a boat that is exclusively powered by an engine. Some motorboats are fitted with inboard engines, others have an outboard motor installed on the rear, containing the internal combustion engine, the gearbox and the propeller in one portable unit. An inboard-outboard contains a hybrid of an inboard and an outboard, where the internal combustion engine is installed inside the boat, and the gearbox and propeller are outside. There are two configurations of an inboard, V-drive and direct drive. A direct drive has the powerplant mounted near the middle of the boat with the propeller shaft straight out the back, where a V-drive has the powerplant mounted in the back of the boat facing backwards having the shaft go towards the front of the boat then making a ''V'' towards the rear. Overview A motorboat has one or more engines that propel the vessel over the top of the water. Boat engines vary in shape, size, and type. Engines are installed ...

Speed Boat And Water Skiier
In everyday use and in kinematics, the speed (commonly referred to as ''v'') of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is not the same as velocity. Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). For air and marine travel, the knot is commonly used. The fastest possible speed at which energy or information can travel, according to special relativity, is the speed of light in a vacuum ''c'' = metres per second (approx ...

Power-to-weight Ratio
Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance. The inverse of power-to-weight, weight-to-power ratio (power loading) is a calculation commonly applied to aircraft, cars, and vehicles in general, to enable the comparison of one vehicle's performance to another. Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle. Power-to-weight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planing (sailing)
Planing ( ) is the mode of operation for a waterborne craft in which its weight is predominantly supported by hydrodynamic lift, rather than hydrostatic lift (buoyancy). Many forms of marine transport make use of planing, including fast ferries, racing boats, floatplanes, flying boats, seaplanes, and water skis. Most surfboards are planing or semi-planing hulls. Beyond planing, fast vessel designs have seen a transition to hydrofoil designs. History The earliest documented planing sailboat was a proa built in 1898 by Commodore Ralph Munroe. It was capable of speeds of more than twice the hull speed. Planing a sailing dinghy was first popularised by Uffa Fox in Britain. In 1928 Fox introduced planing to the racing world in his International 14 dinghy, ''Avenger''. That year he gained 52 first places, 2 seconds, and 3 third places out of 57 race starts. This performance was noticed by other designers who further developed them. Over the years many dinghies have acquired the ...

Yachting
Yachting is the use of recreational boats and ships called ''yachts'' for racing or cruising. Yachts are distinguished from working ships mainly by their leisure purpose. "Yacht" derives from the Dutch word '' jacht'' ("hunt"). With sailboats, the activity is called sailing, and with motorboats, it is called powerboating. Racing History The history of sailing dates back to prehistoric times but the racing of sailing boats is believed to have started in the Netherlands some time in the 17th century. Soon, in England, custom-built racing "yachts" began to emerge. In 1851, the Royal Yacht Squadron in Cowes challenged the American yacht ''America''. The race took place in the Solent. The ''America'' won the race and took the trophy, the America's Cup, back to the US where, held by the New York Yacht Club, it remained until 1983. The cup was then lost to the Royal Perth Yacht Club of Australia, which entered the '' Australia II'' into the contest. Meanwhile, yacht racing continu ...

Waterskiing
Water skiing (also waterskiing or water-skiing) is a Surface water sports, surface water sport in which an individual is pulled behind a boat or a Cable skiing, cable ski installation over a body of water, skimming the surface on two skis or one ski. 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 (continent), Australia, Europe, Africa, and Americas, 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 skii ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Motorsports At The 1908 Summer Olympics
At the 1908 Summer Olympics, three motorboat racing events were contested. Various sources refer to the sport as "water motorsports", "motor boats",Cook, p. 227 and "power boating". The 1900 and 1908 Summer Games were the only ones to feature motorised sports (motor racing was featured in 1900). The IOC has never decided which events were "Olympic" and which were not. All three events used the same distance: five laps around an 8- nautical-mile course for a total of . In each of the events, multiple boats started; however, only one finished due primarily to the gale that was blowing during the course of the competition. Events were held on 28 August and 29 August 1908. Medal summary The water motorsports event was quickly abolished, because after these games the IOC decided that the Olympics was not intended for motorized competition. Participating nations 17 boaters from 2 nations competed. * * Medal table Sources: Events Class A — Open class The open class was sched ...
