External thrusters, such as the pod-based EX-series are a practical thruster solution for boats between 6 and 18 metres in length. These pod thrusters are good where a tunnel thruster cannot be fitted. They can also work as a stern thruster.
External thrusters can be used in sailing boats, catamarans, motorboats and houseboats. They can be fitted made from steel, aluminum, wood or GRP. The flexible mounting, at the extreme bow of the boat, allows a deeper position underwater. This creates optimal leverage compared to conventional thrusters. EX thrusters can, therefore, move larger boats, using less power than conventional thrusters.
