The stern thruster, like the bow thruster, improves boat manoeuvrability and greatly simplifies berthing, even with larger boats. It is installed at the stern, with the motor inside the hull and the propeller tunnel outside the transom.
With a bow thruster and stern thruster, maneuvering the boat to a side tie berth between two vessels is made far easier because the bow can be effectively ’’steered’’ using the reversible propeller of the thruster.
