Steel Waterjet S-3/CA
The S3/CA incorporates numerous improvements made possible by advanced design calculation methods and testing and production techniques. The compact reversing bucket and steering nozzle enables superior position keeping and maneuverability at low and high speed. This reduces fuel consumption and lowering noise and emissions in harbor maneuvering, as well as saving time and increasing safety. In high speed turns the steel series maintains speed very efficiently, which is a highly appreciated benefit for patrol vessels and others alike.
Low and high-speed performance in the same package
At the heart of the waterjet is the fully stainless steel mixed flow pump. There are different impellers depending on application. Efficiency has been achieved by using the latest computational fluid dynamics (CFD) techniques combined with extensive testing in the cavitation tunnels at the KONGSBERG Hydrodynamics Research Centre. The S3/CA waterjets can be individually optimized and selected based on boat design requirements and operational profile.
Higher speed in curves
The steering nozzle design in S3/CA provides 2 – 3 knots higher speed in tight turns. In addition, full scale tests confirm the nozzle to be significantly quieter compared to the earlier design.
Heavy duty stainless steel pump unit
The S3/CA is always equipped with a duplex stainless-steel pump unit providing the best possible durability under any circumstances. High end components are used, providing long life and reliable service. These are enabling up to 10,000 h or 5-year time service/replacement of wear parts.
Bollard pull capability closing the gap to conventional propulsors
The S3/CA waterjets standard inlet provides very good low and mid speed performance. In practice, this means increased bollard pull thrust comparable to conventional propulsors. High-speed inlets are available for speeds exceeding 45 knots.

Modular interceptor trim
All S3/CA waterjets can be delivered with modular interceptor trim tabs bolted directly onto the waterjet, including hydraulics and control panels for electronics. Modular bolt installation enables easy retrofitting. The interceptor trim system improves acceleration and low speed characteristics, in addition to trim angle adjustment.
Remote control systems
Kongsberg Maritime can supply a number of different control systems, ranging from rugged, standardized systems and up to multi station, custom design systems.
Available between size 25 to 63. As a standard steel series has inlets made of marine grade weldable aluminum as an integral part of waterjet unit. This alternative means quick and cost effective installation at the shipyard.
