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.
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.
USCGC Hamilton (WHEC-715) was a United States Coast Guard high endurance cutter and the lead ship of its class. It was based at Boston , Massachusetts from commissioning until 1991, then out of San Pedro , California before it was moved to its last home port in San Diego , California.
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 ...
The Hamilton-class cutters' hull was designed with a V cross section, and through tank testing the hull was expected to survive and stay afloat longer after suffering damage. [ 6 ] They are powered by a Combined Diesel or Gas ( CODOG ) system consisting of two diesel engines and two gas turbines , and have controllable-pitch propellers .
USCGC Alexander Hamilton (WPG-34) was a Treasury-class cutter.She was named after Founding Father and the first U.S. Secretary of the Treasury, Alexander Hamilton. [1] Sunk after an attack by a German U-boat in January 1942, the Hamilton was the U.S. Coast Guard's first loss of World War II.
In the early 1950s Hamilton developed the technology to accurately meter fuel in jet engines, and its fuel controls were employed on Boeing 707s and Douglas DC-8s, as well as most other Pratt & Whitney jet engines. In 1952, Hamilton Standard opened its plant in Windsor Locks, Connecticut.
It is powered by a pair of Hamilton HJ422 water jets powered by a Caterpillar CAT C12 ACERT diesel engine that produces 1,500 hp (2×750). It has a cruising speed of 35 knots (65 km/h), can maneuver 360 degrees in small circles and make sudden stops over short distances.
