  • Self-steering system for watercraft
    Patent number: 5860842
    Abstract: An automatic controller for the helm of a watercraft uses sensors responsive to starboard and port contacts, with the predominating of the starboard and port contacts signalling the heeling of the watercraft. A transmitter attached to the person of the operator of the vessel is triggered should the operator fall into the water, to transmit a signal to the receiver attached to the electronic controller and thereby cause the watercraft to turn into the wind and prevent the distance between the vessel and the overboard person from increasing.
