Claim 13:
14. An apparatus for determining a length of rode traversing a gypsy of a windlass on a boat in real time during an anchoring operation, the apparatus comprising a windlass module configured to securely attach onto the windlass in a fixed position, wherein the windlass module comprises electronic and/or electromechanical motion sensing instrumentation configured to provide parameter values determining a rate and amount of angular rotation of the windlass, wherein the motion sensing instrumentation comprises:
a processor and a wireless communications interface;
at least one sensing device selected from the group consisting of a gyroscope, an accelerometer, a strain gage, a magnetometer, an inertial measurement unit, an eCompass, a directional electromagnetic radiation receiver, and a directional microphone; and
tangible media comprising data and instructions operable for the processor to: acquire a plurality of measurement values from each of the sensing devices,
determine a rotational motion of the windlass based on the measurement values acquired from at least one of the sensing devices, and
transmit information selected from the group consisting of the measurement values acquired from at least one of the sensing devices, a characteristic of the rotational motion of the windlass, a direction of windlass rotation, and an angle of windlass rotation to a remote computing device in real time through the wireless communications interface;, whereby the remote computing device is operable to determine a signed incremental angle of windlass rotation based on the information received from the windlass module.
