er who developed the modern jetboat
Jetboat
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 a propeller in the water below or behind the boat, a jetboat draws the water from under the boat into a pump inside the boat, then expels it through a nozzle at the...

Hamilton never claimed to have invented the jet boat. He once said "I do not claim to have invented marine jet propulsion. The honour belongs to a gentleman named Archimedes

Hamilton survived an aeroplane accident returning to Rongotai Airport (Wellington) in poor conditions on 19 February 1937. The collision with the anemometer took the starboard wing off the Miles Falcon Six he was travelling in, and killed pilot Malcolm "Mac" McGregor.

. He decided to develop his own heavy machinery. He built a workshop, developed an excavator with an earth scoop and built a dam to supply water for a hydro electric plant to supply power for domestic use and for his engineering projects, and started a manufacturing business.

Jet boats

In the 1950s Hamilton set out to try to build a boat that could navigate the shallow fast flowing rivers where he lived. The rivers were too shallow for propeller driven boats to navigate as the propeller would hit the river bottom.

He investigated the American Hanley Hydro-Jet, a model which drew in water and fired it out through a steerable nozzle underneath the boat. Even when further adapted it did not work well. An employee suggested to have the nozzle just above the waterline.

When he took one of his early demonstration jet boats to the US, the media scoffed when he said he planned to take it up the Colorado River (U.S.), but in 1960 a Hamilton jet became the first boat to travel up through the Grand Canyon

. The critics were silenced further when the boat also went down river through the canyon.
