ABSTRACT:
An anchorless boat positioning system dynamically and automatically maintains a boat at a selected anchoring location within water without the use of a conventional anchor by using a steerable thruster whose thrust and steering direction are determined on the basis of position information signals received from global positioning system (GPS) satellites and heading indication signals from a magnetic compass. The anchorless positioning system continuously monitors the position and heading of the boat and compares it with the stored coordinates of the selected anchoring location to generate control signals for the steerable motor.
