Improved maneuverability

These auxiliary propulsion units with optimized hydrodynamic efficiency lead to significantly increased maneuverability for traditional shaftline equipped commercial and large pleasure craft vessels. Special versions of this thruster system are available, for example a solution where the thruster is mounted in a rubber sealing. This reduces structure borne noise significantly and makes it possible to remove the thruster from the vessel for maintenance work without dry docking.


  • Ease of maneuverability
  • Robust, solid and compact design
  • Vessel specific propeller design assuring optimized efficiency or low noise emission
  • Controllable or fixed pitch propeller available
  • Highest reliability
  • Ease of installation and maintenance
  • Possibility to operate the thruster with biodegradable lubrication oil
