ABSTRACT:
A pivotal bow thruster adapted to be adjustably pivoted about a stem of a boat, which enhances attainment of smooth, safe docking of the boat, with better control, and minimal difficulty. The bow thruster comprises two propellers which, when spinning, thrust the bow of the boat to starboard or to port, and a mechanism for pivoting the propellers about the stem of the boat. This pivoting mechanism comprises a pivoting arm coupled to the propeller unit and a gear train which, when activated, rotates the pivoting arm.
