  • The trusted name in Jet Technology

    HamiltonJet waterjets are manufactured at the CWF Hamilton & Co factory in Christchurch, New Zealand. The factory is dedicated solely to the manufacture of waterjets and control systems, with the majority of components engineered inhouse.

    All HamiltonJet waterjets are custom built to specifically suit each application, with most components for each unit manufactured together to ensure high quality of product and improve ongoing maintenance over the life of every waterjet which leaves the factory.

    Scope of Supply

    Unlike some manufacturers, HamiltonJet provides complete integrated waterjet packages. This includes transition duct, complete waterjet and controls for the jet.

    Where Hamilton electronic controls are used, the package can be configured to Dynamic Positioning (DP) systems, Autopilot systems, Engine and Gearbox control systems across one or more stations.
