  • Patent number: 12703470
    Abstract: The retractable bow thruster and trolling motor is a system designed for permanent installation into a boat hull. When not in use, the thruster retracts fully into the boat hull, with a plate or cowling sealing against a recess within the boat hull. This seal prevents water intrusion and avoids physical damage to the bow thruster from waterborne debris or shallow water conditions. When needed, the thruster extends outward from the bottom of the boat hull and is rotatable to provide thrust in any direction. In combination with an optional electronic control systems, the bow thruster will increase the maneuverability of the boat for docking or undocking, as well as maintaining position in the water.
