Ducted Propeller (Nozzle)
A ducted propeller is the best solution when the operating speed of the vessel is below 10 knots (18,5 km/h). Due to the shape of the nozzle around the propeller, it acts like an airplane wing, where the water speed around the wing shape generates extra thrust due to the ‘lift’ effect of the nozzle.

Maximum Propeller Efficiency
Current Motion thrusters are designed to accommodate a large propeller diameter, maximising efficiency at low vessel speeds. Thanks to the electric drive and carefully selected gear ratios, the thruster can also run at maximum load with a smaller propeller, since the drive line is engineered to keep the propeller operating within its most efficient range, regardless of diameter.
Low-Noise Operation
To minimise sound levels, Current Motion uses a pulling propeller (tractor) configuration, which creates an optimal wake field ahead of the propeller. This means the propeller can be designed purely for maximum efficiency, without compromises to the blade design to compensate for a disturbed wake field.
Product features
Increased efficiency
A nozzle around the propeller of an Azimuth thruster enhances its efficiency. It directs water flow better, creates lift force, and improves thrust performance. This leads to fuel savings and lower operating costs, especially at low vessel speeds.
Enhanced maneuverability
The vessel’s maneuverability is improved with the nozzle design, enabling precise control of thrust direction in confined areas such as harbors, ports, and narrow waterways.
Improved bollard pull
A nozzle added to the Azimuth thruster increases bollard pull and enables the vessel to exert more force during towing or adverse weather. This enhances the vessel’s versatility and capabilities.
Noise reduction
The nozzle design reduces turbulence and vibration around the propeller, resulting in a quieter onboard environment for passengers and crew, enhancing comfort and safety.
Need advice on the right azimuth thruster?
Choosing the right thruster depends on your vessel, operating profile and performance requirements. Our team helps you determine the best configuration for your application.
