Claim 10:
11. The windlass module of claim 1 further comprising:
a radiation emitter secured in a first fixed position on the windlass module, the radiation emitter being configured to emit radiation in a generally radial direction from the windlass wherein a portion of the emitted radiation is operable to reach a radiation reflector at a fixed position in the environment of the boat having an unobstructed line of sight to the windlass module, and be reflected back to the windlass module on the windlass, and
a radiation receiver secured in a second fixed position on the windlass module, the radiation receiver being configured to receive the portion of the emitted radiation being reflected back to the windlass module on the windlass;
a processor and a wireless communications interface; and
tangible media having data and instructions operable for the processor to:
determine the signed incremental angle of windlass rotation based on receiving the reflected portion of the emitted radiation, and to wirelessly transmit the signed incremental angle of windlass rotation to a remote computing device in real time using the wireless communications interface;, whereby the remote computing device can determine a length of rode traversing the gypsy of the windlass in real time based on receiving the signed incremental angle of windlass rotation.
