HamiltonJet has successfully transitioned its innovative LTX waterjet from concept to commercial operation, with the first LTX36 units now powering the 20-meter passenger ferry Inselexpress 2, designed by Van Dorresteijn Design. Built by Next Generation Shipyard and equipped with twin Volvo Penta D8 engines, the vessel achieved its predicted top speed of 23.5 knots during sea trials, validating the LTX series’ performance for mid-speed maritime applications.
Launched in 2023, the LTX waterjet series—available in LTX36 and LTX53 models—marks HamiltonJet’s entry into the low- to medium-speed market traditionally dominated by propellers. Inspired by the efficient propulsion of the moon jellyfish, the design uses a larger nozzle, reduced jet velocity, and a lightweight structure to deliver high thrust, manoeuvrability, and energy efficiency.
Key benefits include up to 40% more bollard pull than comparable jets, low-loss steering for reduced fuel use, compact installation for versatile powertrain options, and optimised hydrodynamics for maximum efficiency.
According to HamiltonJet’s Managing Director Ben Reed, the LTX is a “game changer” designed for evolving operational needs, including hybrid and electric propulsion.
With additional vessels—including fully electric ferries in New Zealand and Europe—already in development, the waterjet LTX series represents a major step forward in clean, adaptable marine propulsion.
