Waterjets

The HamiltonJet Waterjet is one of the most the advanced and innovative marine propulsion systems in use today, and is at the forefront of waterjet propulsion technology.  HamiltonJet pioneered the development of the modern waterjet system over 50 years ago, adapting technology initially designed for shallow river operation to suit all manner of inshore and offshore vessels, and in doing so discovering a wide range of advantages waterjets have over other forms of propulsion.

The HamiltonJet Waterjet is particularly suited to high speed vessels operating in the 20 to 50 knot range, but can also be successfully used in displacement speed vessels in certain situations.

It is important to understand that waterjet propulsion operates quite differently to conventional propeller propulsion systems.  This results in many advantages, along with a few disadvantages, when compared to propellers for any particular application.  Anyone considering waterjets needs to understands how they work and how best to set up a vessel to make best use of this superior propulsion technology.

Model Range

The current HamiltonJet waterjet range includes models for power inputs from 150 to 3000kW, for vessels typically up to 60m in length.  All models include features such as integral intake and transition duct for easy installation, as well as steering and reverse components.  All but the smallest units include fully integrated hydraulic reverse systems with jet-driven hydraulic pump, control valves & oil-cooler cast into the waterjet intake.

HamiltonJet's smaller range of waterjets is known as the HJ Range - 8 models ranging from 200mm to 400mm diameter impellers.  HJ waterjets are generally suitable for 6-20m craft, depending on the number of waterjets used, hull displacement, and the vessel's application.  Control systems range from fully manual, to manual hydraulic to the electronic blue ARROW control system.
HJ series waterjets are sold and supported through HamiltonJet's extensive network of Distributors.

HamiltonJet's larger range of waterjets is known as the HM Range - 7 models ranging from 420mm to 810mm diameter impellers.  HM waterjets are generally suitable for 18-60m craft using two or more engines and waterjets.  Control systems are hydraulic or electronic.
Because of the more technical application criterea for HM series waterjets, these models are generally sold and supported from the HamiltonJet factory and Regional Offices, with local assistance from Distributors.

HamiltonJet also designs and manufactures hydraulic and electronic control components for all its waterjet models.  Its electronic control systems can integrate with a range of other vessel systems, such as engine and gearbox controls, Autopilot, Voyage Data Recorders and Dynamic Positioning Systems to provide complete vessel maneuvering control.
