We must master the law of tidal changes. Tide tables serve these aspects.

Tide tables generally include daily forecast tables of major ports (usually including the time and height of high tide and low tide, hourly tidal level of some ports), differential ratio of affiliated ports, tidal information and calculation of tidal level at any time. Tide tables are suitable for coastal areas and have great practical value for offshore fishing enthusiasts and offshore workers.
