For each ship, we can offer a solution that is specifically catered to the ship's design, the ship's sailing area and the customer's preferences. Bow thrusters play a prominent role in shipping and are almost as important as the main propulsion. That is why reliability and life-span have become important factors; both of which are engrained into our family business. All bow thrusters are available in diesel, electric, hybrid or hydraulically driven versions.
Tunnel Thruster
The most efficient bow thruster solution: maximum thrust per kW, quiet operation and precise control thanks to the proven tunnel design.
Steering Grid Bow Thruster
Compact, efficient and powerful – the steering grid bow thruster delivers maximum manoeuvrability with minimal draught.
Channel Bow Thruster
Advanced manoeuvring solution – multiple channels, one compact housing, maximum control of thrust direction.
Smart-Steer Bow Thruster
Directional thrust through channel inlet and steering grid – maximum control with sufficient draught.
Compact Tunnel Thruster
Specifically developed for shallow-draught vessels – compact tunnel design with full transverse thrust.
Tunnel / Steering Grid Combination Bow Thruster
Full thrust in all directions – a unique Kalkman development for manoeuvring and propulsion.
24V Tunnel Bow Thruster
Specifically developed for small passenger vessels and pleasure craft – efficient 24-volt tunnel thruster by Kalkman.
