Abstract: The invention provides a device and method for producing substantially kinematic steering of a boat whose yaw rate and direction is approximately proportional to the rate and direction that a steering device such as a steering wheel is being operated. The invention provides a helmsman a precise method of steering that is relatively independent of such considerations such as the size and weight of the boat, conflicting currents and winds, windage, the size of the rudder and the overall inherent controlling characteristics of the boat. When the steering device is not being operated, the boat continues on a straight course; however, when the steering device such as the steering wheel is turned in one direction or the other, the steering rate of the boat is relatively dependent upon the rate that the steering wheel is being turned.
