Abstract
A device for controlling the heading of a water craft using a propulsion device which pulls the water craft is disclosed. The device includes a motor with a variable thrust orientation and a controller for controlling the direction of the thrust of the motor. A feedback circuit, including a compass in a substantially fixed relationship to the motor, provides a feedback signal to the controller indicative of the direction of the thrust of the motor. A heading designator provides a desired heading signal to the controller. The controller maintains the heading of the water craft in the desired heading in response to the desired heading signal and the feedback signal by varying the orientation which is of the thrust.
