Waterjets outperform propellers at service speeds above 25–30 knots and deliver
Because there are no exposed appendages below the hull, waterjets enable safe shallow-draft navigation. This combined with their precise manoeuvrability make them an ideal propulsion choice for high-speed ferries and patrol craft.
A waterjet propulsion system moves a vessel by accelerating water through a controlled flow:
This simple yet powerful design gives waterjet-powered vessels exceptional manoeuvrability, shallow-water capability, and reliable performance at high speeds.

Wärtsilä’s Propulsion Control System PCS consists of control devices, displays, indicators and modules, designed to operate with any propulsion configuration on a modern ship.
Wärtsilä’s Waterjet Data Collection Unit (WDCU) can monitor the waterjets: their RPM, steering angles, temperatures, and pressures. It uses the data for predictive maintenance and to provide operational insights to the vessel’s operator.
Wärtsilä’s modular WXJ waterjets are a proven choice for high-speed ferries. They help operators keep to tight schedules with reliable performance and fast, precise manoeuvring in terminals. Passengers benefit from a quieter, smoother ride thanks to low noise and vibration.
Wärtsilä waterjets integrate seamlessly with electric and hybrid propulsion systems. They have a strong track record on battery-electric and LNG-powered ferries, including world-leading vessels from Incat and Baleària.

Because Wärtsilä waterjets enable crash stops, j-turns and shallow-water operation, they are ideal for naval and patrol crafts. Their cavitation margins are superior. Inboard hydraulics simplify maintenance and reduce environmental risk, while robust materials ensure durability in demanding conditions.
From high-speed ferries to advanced patrol craft, Wärtsilä waterjets power vessels worldwide. Each project demonstrates efficiency, manoeuvrability, and future-ready integration.
