ABSTRACT:
Improved nautical clock apparatus and methods are provided. The nautical clock apparatus is basically comprised of a clock base and a tide state indicator attached to the base. Means are attached to the tide state indicator and to the base for causing the indicator to indicate the tide state based on a time of about 12 hours and 25.235 minutes between high tides and a continuous correction to such time which lengthens and shortens such time on a cycle whereby it is longer during one or more portions of each lunar month and shorter during one or more other portions of each lunar month.
