ABSTRACT:
A steering system for a watercraft provides a position command signal indicative of a position of a rudder. An azimuth or location sensor senses an azimuth or a location of the watercraft, respectively. A control data input device selectively provides a control device with a manual mode signal and an autopilot mode signal. The autopilot mode signal is accompanied by a target azimuth signal or a target location signal. The control device controls the position of the rudder unit based upon the position command signal in the manual mode. The control device controls the position of the rudder unit such that the actual azimuth coincides with the target azimuth. The control device places the watercraft in the manual mode in place of the autopilot mode without the manual mode signal if the position command signal changes while the control device controls the position of the rudder unit in the autopilot mode.
