HamiltonJet Propulsion System

For the last 54 years, HamiltonJet has been working with vessel designers and builders to create waterjet propulsion systems which deliver optimum performance and efficiency.

HamiltonJet pioneered the development of the modern waterjet over 50 years ago, and the company continues its innovative traditions today.Constant design improvements, driven by an active research and development programme, keeps HamiltonJet at the forefront of waterjet technological evolution.

HamiltonJet creates superior waterjet propulsion systems suitable for commercial applications, workboats, patrol and military craft, and pleasure boats.Today, waterjets are the preferred propulsion choice where high efficiency, outstanding manoeuvrability, shallow draft capability and low maintenance are key requirements.

The HamiltonJet waterjet is one of the most 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 60 years ago, adapting technology initially designed for shallow river operation to suit all manner of inshore and offshore vessels. In doing so we discovered the wide range of advantages waterjets have over other forms of propulsion.

The HamiltonJet Waterjet is particularly suited to high speed planing 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 understand how they work and how best to set up a vessel to make best use of this superior propulsion technology.

Today’s HamiltonJet offers many advantages over competing drive systems:

  • Reliability: Fewer moving parts with most major components inboard and out of harm’s way
  • Maneuverability: Split duct reverse bucket & JT nozzle combine for excellent maneuverability
  • Speed: Optimized for speeds from 25-50 knots
  • Efficiency: Meets or exceeds the best prop designs at speed of 30 knots or better
  • Shallow water operation: The ability to go where props simply can’t
