HamiltonJet has transitioned its innovative LTX waterjet from concept to commercial reality, with the first LTX36 units commissioned on the 20-metre passenger ferry Inselexpress 2 in The Netherlands. Built by Next Generation Shipyard and powered by twin LTX36 jets with Volvo D8 engines, the vessel achieved its predicted top speed of 23.5 knots during trials, confirming the design’s performance potential in the 20–30 knot range.

Launched in 2023, the LTX 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 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 LTX series represents a major step forward in clean, adaptable marine propulsion.
