Abstract
A bow and stern thruster apparatus includes a motor, a propeller, a battery, a radio receiver, control logic, and power driver circuitry; together forming a fully integrated thruster unit that slides up and down along a guide device to a hull attachment fixture near the water line of a boat. The deployed thruster unit can act as a bow or a stern thruster depending on where the guide device and attachment fixture are mounted to the boat. The thruster unit is retracted by raising it along the guide device to be stowed well above the water line, or to be removed entirely from the hull.
