1. A method for determining a length of rode traversing a gypsy of a windlass on a boat in real time during an anchoring operation, the method including steps of:
emitting directional radiation from a windlass module securely attached onto the windlass of the boat in a fixed position, wherein the radiation is selected from the group consisting of sound and electromagnetic radiation;
detecting a portion of the directional radiation emitted from the windlass module with a radiation receiver; and
determining a signed incremental angle of windlass rotation between a prior and a current angular position of the windlass in real time depending on a characteristic of the detected directional radiation.
