Jetsprinting as an organised sport originated in New Zealand in 1981 by Pat Quinn and his wife, Margaret. [4] Margaret spectated jet boat Marathons which Pat competed in, but wanted to see more of the race, suggesting a smaller, more condensed track.
A jetboat is a boat propelled by a jet of water ejected from the back of the craft. Unlike a powerboat or motorboat that uses an external propeller in the water below or behind the boat, a jetboat draws the water from under the boat through an intake and into a pump-jet inside the boat, before expelling it through a nozzle at the stern.
Sir Charles William Feilden Hamilton OBE (26 July 1899 – 30 March 1978) was a New Zealand engineer who developed the modern jetboat, and founded the water jet manufacturing company, CWF Hamilton Ltd. Hamilton never claimed to have invented the jet boat. He once said "I do not claim to have invented marine jet propulsion.
The boat was reported to reach a speed of four mph moving upstream. [7] [8] [9] On December 21, 1833, Irish engineer John Howard Kyan received a UK patent for propelling ships by a jet of water ejected from the stern. [10] In April 1932, Italian engineer Secondo Campini demonstrated a pump-jet propelled boat in Venice, Italy. The boat achieved ...
Grand Prix (GP) is a class of boats featuring supercharged big-block V8 piston engines producing as much as 1,500 horsepower. The 23- to 26-foot craft are fast—routinely attaining speeds in excess of 170 miles per hour (273.5 km/h) in the straights. This class of boat races in the United States, Canada, Australia and New Zealand.
Chevron Engineering Specialties Ltd is a New Zealand based kit-car and race-car manufacturer owned by Dan, Evan, and Barbara Fray and founded in 1980. [18] It is based in Massey, Auckland and manufactures three different models, with the Aprisa and Cypher competing in New Zealand sports car racing.
These departures resulted in a lack of senior leadership at Team New Zealand, which along with a relative lack of funds, caused the team to resort to radical design innovations in an attempt to defend the cup with raw boat speed alone. NZL 82 was notable for her design innovations. The most controversial of these was the so-called "HULA" (Hull ...
Each "Formula" level follows a different set of regulations that specify the design of the boat and engine, as well as the rules of competition. The most common form of inshore powerboat racing involves a race around a two pin (buoy) or multi-pin circuit of approximately 1.5 – 2 km in length. Each pin marks a turn in the course.
