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.
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 ...

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.
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.
They are powered by twin MWM TD-232 V-12 diesels which each develop 370 hp, which are coupled to a Hamilton 1341 water jet unit. The crafts have a top speed of 25 knots. They are armed with a 7.62-mm MG and a Furuno FR 8030 Radar however they resemble oilfield crew boats.
It is an inboard/outboard design powered by a 500 hp (370 kW) Cummins diesel inboard engine with a Hamilton jet drive. [ 3 ] [ 4 ] The boats are equipped with radar , electronic compass, GPS , and other electronic navigation systems, loud-hailer, and both HF and VHF-FM radios. [ 3 ]
