Description

Improved maneuvering with bow thrusters of ZF

Key Facts

• Vessel specific propeller design
• Different propeller installations possible
• From 50 to 2,500 kilowatts

The tunnel thrusters with optimized hydrodynamic efficiency lead to significantly increased maneuverability for traditional shaftline equipped commercial vessels and pleasure craft boats. In auxiliary use the ease of mooring can be improved. In essential use for more demanding applications, such as dynamic positioning, performance can be optimized. The thruster can be delivered in a performance range of 50-2,500 kW.
