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 behind the boat, a jetboat draws the water from under the boat into a pump-jet inside the boat, then expels it through a nozzle at the stern.

Jetboats were originally designed by inventor Bill Hamilton to operate in the fast-flowing and shallow rivers of New Zealand to overcome the problem of propellers striking rocks in such waters, although Italian inventor Secondo Campini demonstrated a similar vessel as early as 1931 in Venice.

Jet boats are highly maneuverable and can often be reversed and brought to a stop within its own length from full speed in a maneuver known as a Hamilton turn.
