ABSTRACT:
A housing having a water conducting channel therethrough is secured to the underside of a vessel below the water line thereof. Water is urged through the channel by a propeller which unidirectionally rotates about a vertical axis. The direction of movement of the vessel is in response to the direction of movement of water through the channel which is controlled by operatively movable gate means which direct water flow through the channel along selective paths for contact with discriminate sectors of the cylinder described by the rotating propeller.
