 The
jet boat was invented in New Zealand, born from the need to be able
to navigate shallow rivers for high country farmers and the like and
has evolved into one of the greatest thrill rides on water.
Unlike a conventional outboard motor, the jet boat uses an internal
impeller to provide propulsion. Water is drawn in through an inlet
in the bottom of the boat and driven out through a nozzle at the rear
with great force. Turning is accomplished by moving the nozzle laterally;
braking and reverse are achieved by
using a deflector similar to the reverse thrust bucket on a jet aircraft.
With their shallow draft and incredible power and agility, jet boats
can tackle almost any river in any conditions, ranging from wide,
shallow rivers to the frighteningly narrow confines of gorges. They
can travel up to speeds of 80km/hr in water as  shallow
as 10cm in depth. Expect your driver to perform the “Hamilton
Turn” – a high speed 360-degree turn, guaranteed to get
the heart rates racing.
Typically, the drivers will take you up river as fast as conditions
allow, steering the boat as close to the riverbanks, rocks and cliffs
as they can, giving you a sensation of speed and danger few other
activities provide. |
