<p>A system for controlling the navigation of a recreational boat (100), such as a fishing boat, between waypoints representing successive positions around a navigation route. The system includes an input device (212, 214) for setting the waypoint positions, a position detector (216) to detect the actual position of the boat (100), a trolling motor (102) to produce a thrust to propel the boat (100), a steering motor (202) to control the direction of the thrust, and a heading detector (206) to detect the actual heading of the boat. The system also includes a control circuit (200) which determines a desired heading using a desired waypoint and the actual position of the boat (100), and generates a steering control signal applied to the steering motor (202) to steer the boat from the actual position to the desired waypoint. The system operates in various modes which allow repeated navigation of the boat around a navigation route. The system provides for automatic waypoint storage as the boat is maneuvered around a navigation route. <IMAGE></p> |
