Retractable azimuthing thruster
The retractable azimuth thruster range provides extra thrust when needed. The hydraulic lifting and lowering of the unit is fast and it retracts into the hull when not in use.

Improved manoeuvring and extra thrust
The retractable range uses components from our standard azimuth thruster range and provides fast hydraulic lifting and lowering of the unit, enabling it to retract into the hull when not in use, reducing the vessel's drag. The UL models are designed for horizontal drive with automatic drive shaft disconnection system. ULE models are designed for vertical drive. Both are available with CP or FP propellers. The lifting and lowering is activated by a push button on the bridge. Unlocking/locking in position and the engagement of the drive shaft coupling is automatic.
Key features
- Improved manoeuvring
- Combined steering and propeller thrust at low speed
- Compact design and easy installation
