ABSTRACT:
A moon clock for indicating a phase of the moon. The moon clock comprises a moon disk rotatable about a central axis having moon representation means and a continuous scale disposed on the front surface thereof, drive means for rotating the moon disk at a rate corresponding to the rate of the lunar orbit, marker means for marking a position of the moon representation means that indicates a phase of the moon at a given time and for marking a division of the continuous scale, and a stationary vernier scale positioned adjacent to the continuous scale for measuring a fractional part of the division of the continuous scale marked by the marker means. Also provided is a tide clock for indicating a state of the tide. The tide clock comprises a tide disk rotatable about a central axis having tide representation means for representing a high tide disposed on the front surface thereof, marker means for marking a position of the tide representation means that indicates the time of the high tide and drive means for rotating the tide disk at a rate of approximately one revolution every 12 hours and 25 minutes. Also provided is a nautical clock comprising both the moon clock and the tide clock. The moon clock of the nautical clock is particularly useful in setting the tide clock.
