Work boat water-jet drive HJ213

for patrol boats

Designed principally for Trailerable boats using petrol engines, the HJ212 is the most popular waterjet unit in the world. Setup options include a close coupling system to keep space taken by the engine/waterjet to a minimum, and the "Turbo" impeller, specifically designed for use in highly aerated water, such as river rapids and surf conditions. Performance High speed performance and efficiency – advanced impeller and intake designs provide peak efficiency and performance over a wide speed range. Low speed performance – high thrust at low speeds ensures excellent station-keeping, bollard pull, load carrying and manoeuvring. Acceleration – ability to apply full power at lower speeds ensures fast acceleration for patrol boats, rescue craft, pilot boats and recreational vessels. CONTROL Steering control – HamiltonJet’s JT steering system out-performs all others, reducing thrust losses when steering to give tighter turns and maintain vessel speed during the turn. Ahead / Astern control – HamiltonJet’s split duct reverse deflector provides up to 60% of forward thrust, resulting in highly responsive control at slow boat speeds where engine is set to higher than idle RPM and the reverse duct is used to regulate forward and aft thrust. Speed of the controls response – HamiltonJet controls respond quickly to skipper input to improve manoeuvring control and safety. The company develops hydraulic and electronic control systems to maximise control benefits of its waterjets. LIFECYCLE Material specifications – all HamiltonJet waterjets are manufactured using high quality materials to ensure the best mix of durability, weight, corrosion resistance and cost.
