Sends waterjet control history to a vessels VDR (similar to an aircrafts black box) for future reference in the event of an accident.Using a round centrifugal water pump that drew in the water and expelled it through a steer able nozzle under the boat, he was able to achieve an encouraging but unspectacular speed of 11 mile per hour.A slight modification to expel the jet stream above the waterline proved the turning point in marine jet propulsion, increasing speed to 17mph and eliminating all underwater appendages.Waterjet propulsion was at last truly successful and the Hamilton Waterjet was born.
This first type of unit was named Quinnat and consisted of a vertical shaft centrifugal unit, driven through a right angle gearbox. A small direct drive centrifugal type of unit, the Rainbow gave a good performance in a suitable light craft, without the noise of a gearbox. ![]() Following this came the three-stage Chinook unit which increased performance further. Hamilton Jet Parts For Sale Series Was DevelopedThis series was developed into a full range of one, two and three stage units driving a widerange of boats from river-runabouts to off-shore racing craft. This year saw the introduction of the Work Jets - larger, heavy duty units designed for diesel commercial vessels, large launches etc. The WorkJets were the forerunners to todays Hamilton HM Series of larger waterjets. This gave more cockpit space in the boat and employed modern controls and engines. Split duct deflector developed for 1031 jets and then introduced on all Hamilton Waterjets. The split duct design increases astern thrust by directing the jet stream down and to the sides of the boat transom to avoid recycling and increase steering responsiveness. These were multi-stage waterjet units designed for high-speed light commercial craft with power inputs up to 1,600kW. New jet models introduced to fill holes in Hamiltons waterjet range - HJ241, HJ321, HM461. Existingmodels further developed with more efficient intake and screen designs, 0 and 5 degree intake block options, and improved anti-foulinganti-corrosion protection. Largest Hamilton Jet model waterjets developed - HM651, HM721, HM811. Turbo impeller developed along with HJ212 model to replace the multi-stage 773 unit in trailerable boats. The Turbo impeller improves jet performance in aerated water conditions. Control Monitoring Unit (CMU) developed as a fully electronic jet and engine control system for larger waterjets. Nozzle design minimises thrust loss when steering to improve steering control and course-keeping efficiency. MECS (Modular Electronic Control System) supersedes CMU for electronic control. New model features improved design for greater efficiency, ease of installation and lower maintenance, as well as a new aheadastern control systems. Dynamic Positioning interface for MECS developed. This allows MECS to interface with a ships DP system to improve station-holding ability and general safety around oil-rigs.
