Jetski
Jet Ski is the brand name of a personal watercraft (PWC) manufactured by Kawasaki, a Japanese company. The term is often used generically to refer to any type of personal watercraft used mainly for recreation, and it is also used as a verb to describe the use of any type of PWC. A runabout style PWC typically carries 3 people seated in a configuration like a typical bicycle or motorcycle. Kawasaki Jet Ski "Jet Ski" is a proper noun and registered trademark of Kawasaki. The stand-up Kawasaki Jet Ski was the first commercially successful personal watercraft in America, having been released in 1972 (after reaching a license agreement with the inventor of the Sea-Doo, Clayton Jacobson II when his license agreement with Bombardier expired). The Kawasaki Jet Ski was the only commercially successful PWC for almost 16 years, from the introduction of the WSAA in October 1972 through the re-introduction of the sit-down, runabout style Bombardier Sea-Doo in 1988.

Personal Watercraft
A personal watercraft (PWC), also called water scooter or jet ski, is a recreational watercraft that a rider sits or stands on, not within, as in a boat. PWCs have two style categories, first and most popular being a runabout or "sit down" where the rider uses the watercraft mainly sitting down, and the watercraft typically holds two or more people. The second style is a "stand-up", where the rider uses the watercraft standing up. The stand-up styles are built for one rider and are used more for doing tricks, racing, and use in competitions. Both styles have an inboard engine driving a pump-jet that has a screw-shaped impeller to create thrust for propulsion and steering. Most are designed for two or three people, though four-passenger models exist. Many of today's models are built for more extended use and have the fuel capacity to make long cruises, in some cases even beyond 100 miles (161 km). Personal watercraft are often referred by the trademarked brand names of per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sea-Doo
Sea-Doo is a Canadian brand of personal watercraft (PWC) and boats manufactured by Bombardier Recreational Products (BRP). All Sea-Doo models are driven by an impeller-driven waterjet. All Sea-Doo PWC models are currently produced at BRP's plants in Querétaro and Juárez, Mexico. Its Rotax engines are produced at BRP's plant in Gunskirchen, Austria. In 2016, Sea-Doo had a 45.8% share of the PWC market. History Bombardier introduced its first personal watercraft in 1968, called the Bombardier Sea-Doo. It was designed and mentored by Clayton Jacobson II, who would later develop the more successful Kawasaki Jet Ski watercraft. Also heavily involved was Bombardier's Laurent Beaudoin, who was interested in expanding the success of the Ski-Doo snowmobile to the PWC market. Advertised as the "Jet-powered Aqua Scooter", the original yellow Sea-Doo was 5 feet wide and 7.5 feet long, somewhat resembling a flying saucer. In 1968, it was powered by an air-cooled, 320cc engine with a top s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pump-jet
A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and a nozzle to direct the flow of water out of the pump.http://www.hamiltonmarine.co.nz/includes/files_cms/file/JetTorque%2008.pdf Design A pump-jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines. Water enters the pump through this inlet. The pump can be of a centrifugal design for high speeds, or an axial flow pump for low to medium speeds. The water pressure inside the inlet is increased by the pump and forced backwards through a nozzle. With the use of a ''reversing bucket'', reverse thrust can also be achieved for faring backwards, quickly and withou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vehicles Introduced In 1972
A vehicle (from la, vehiculum) is a machine that transports people or cargo. Vehicles include wagons, bicycles, motor vehicles (motorcycles, cars, trucks, buses, mobility scooters for disabled people), railed vehicles (trains, trams), watercraft (ships, boats, underwater vehicles), amphibious vehicles (screw-propelled vehicles, hovercraft), aircraft (airplanes, helicopters, aerostats) and spacecraft.Halsey, William D. (Editorial Director): ''MacMillan Contemporary Dictionary'', page 1106. MacMillan Publishing, 1979. Land vehicles are classified broadly by what is used to apply steering and drive forces against the ground: wheeled, tracked, railed or skied. ISO 3833-1977 is the standard, also internationally used in legislation, for road vehicles types, terms and definitions.

Cavitation
Cavitation is a phenomenon in which the static pressure of a liquid reduces to below the liquid's vapour pressure, leading to the formation of small vapor-filled cavities in the liquid. When subjected to higher pressure, these cavities, called "bubbles" or "voids", collapse and can generate shock waves that may damage machinery. These shock waves are strong when they are very close to the imploded bubble, but rapidly weaken as they propagate away from the implosion. Cavitation is a significant cause of wear in some engineering contexts. Collapsing voids that implode near to a metal surface cause cyclic stress through repeated implosion. This results in surface fatigue of the metal causing a type of wear also called "cavitation". The most common examples of this kind of wear are to pump impellers, and bends where a sudden change in the direction of liquid occurs. Cavitation is usually divided into two classes of behavior: inertial (or transient) cavitation and non-inertial c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lanyard
A lanyard is a cord, length of webbing, or strap that may serve any of various functions, which include a means of attachment, restraint, retrieval, and activation and deactivation. A lanyard is also a piece of rigging used to secure or lower objects aboard a ship."lanyard lan-yrd." Merriam-Webster's Collegiate(R) Dictionary. Springfield: Merriam-Webster, 2004. Credo Reference. Web. 1 October 2012. Origins The earliest references to lanyards date from 15th century France: "lanière" was a thong or strap-on apparatus. Bosun's pipe, marlinspike, and small knives typically had a lanyard consisting of a string loop tied together with a diamond knot. It helped secure against fall and gave an extended grip over a small handle. In the French military, lanyards were used to connect a pistol, sword, or whistle (for signaling) to a uniform semi-permanently. Lanyards were used by mounted cavalry on land and naval officers at sea. A pistol lanyard can be easily removed and reattach ...
