Marine Jet Power’s X-HT waterjets are built for demanding operations like crew transfers and offshore work. Optimized for low to medium speeds (up to 35 knots), they deliver strong thrust at slow speeds-perfect for wind farm CTVs and other workboats. The compact design allows for larger jets in narrow hulls, while low input power keeps weight and fuel use down for efficient, sustainable performance.
Made from duplex stainless steel, Marine Jet Power jets offer industry-leading strength and corrosion resistance. Integrated steering and DPO ensure precise control and easy station keeping during loitering, loading, or docking-so you and your crew can stay on schedule, safely and

Where technology meets reality
Enhanced Thrust and Efficiency
The X-HT jets delivers more thrust compared to other jets in the same range and is optimized for efficiency at slow speeds. This makes the X-HT particularly well-suited for vessels operating in and around wind farms, where precise maneuvering and consistent power are essential.
Space-Saving Design
The compact design allows for larger diameter jets to be fitted into narrower hulls, maximizing thrust without requiring extensive modifications to the vessel’s structure.
Range of Sizes and Power Ratings
The X-HT is currently available in three sizes, the 280 X-HT, 310 X-HT, and 350 X-HT, with maximum power ratings of 611 kW, 800 kW, and 1000 kW respectively. This range of options ensures that there is a suitable model for a variety of vessel types and operational requirements.
Environmentally Friendly
Low-power operation reduces fuel consumption and emissions.
