Bow and stern thrusters have become an important device when moving at low speed.
It makes manoeuvring easier, safer and quicker. The propeller, which is made of maintenance free synthetic material, can run in two directions, thus producing a jet flow to port or starboard. Each propeller is designed to achieve maximum thrust in a small tunnel diameter. This makes manoeuvring in tight spots against a strong current or a shifty wind much easier.
Craftsman Marine specifies the average force of the thrusters, however the starting peak force (1 second) can be easily 60% higher.
