1.1 THE HAMILTON WATER JET
SYSTEM
1.1.1 Introduction
In the modern world, waterjets have rapidly gained
acceptance as the leading means of propulsion for
all types of high speed marine craft including
ferries, work boats, patrol craft and pleasure boats.
Recent advances in waterjet technology have put
them ahead of conventional propeller systems in
both high speed performance and also reliability.
Modern waterjet powered vessels offer many
advantages, such as high efficiency, rapid
acceleration, shallow draft, unrivalled
manoeuvrability and smooth, quiet operation.
Whilst conventional propeller powered craft have
several shortcomings, such as vibration, higher
engine loading and susceptibility to damage from
water borne debris, waterjets generally offer lower
maintenance, longer engine life and simplified
installation.
Hamilton Jet pioneered the commercial
development of the modern waterjet system in the
early 1950's and today have over 30,000 units
installed worldwide. With a complete range of
models suitable for power inputs of up to 3000 kW
per unit, Hamilton waterjets are ideally suited to the
efficient propulsion of a wide variety of high speed
vessels, in either single or multiple configuration,
typically from 5 to 50 meters in length.
Hamilton Jet is dedicated to the production of the
highest quality waterjets and controls systems
designed and manufactured to meet the
requirements of the worlds leading certifying
authorities. Full logistic support for projects is
provided by the global Hamilton Jet organisation
through factory support staff, regional offices and
an extensive network of factory trained distributors
in over 50 locations worldwide.
