Abstract
A system for controlling the navigation of a fishing boat between waypoints representing successive positions around a navigation route. The system includes an input device for setting the waypoint positions, a position detector to detect the actual position of the fishing boat, a trolling motor to produce a thrust to propel the fishing boat, a steering motor to control the direction of the thrust, and a heading detector to detect the actual heading of the fishing boat. The system also includes a control circuit which determines a desired heading using a desired waypoint and the actual position of the fishing boat, and generates a steering control signal applied to the steering motor to steer the fishing boat from the actual position to the desired waypoint. The system operates in various modes which allow repeated navigation of the fishing boat around a navigation route. The system provides for automatic waypoint storage as the fishing boat is maneuvered around a navigation route.
