Claim 16:
17. The system of claim 16 wherein the rotation detection system includes a radiation emitter, a radiation receiver, and a radiation reflector, wherein:
the radiation emitter and the radiation receiver are attached to the windlass module in distinct positions, and the radiation reflector is configured to be supported in the environment of the boat at a fixed position having an unobstructed line of sight to the windlass;
the radiation emitter is configured to send a pulse of radiation to the radiation reflector, and the radiation receiver is configured to sense a reflected portion of the pulse of radiation returning to the windlass from the reflector at the fixed position in the environment; and
the tangible media further comprises data and instructions operable for a processor to determine an incremental angle of windlass rotation based on the sending the pulse from the radiation emitter to the radiation reflector, and the sensing of the reflected portion of the pulse with the radiation receiver.
