Navy OCS Navigation Practice Test

The main purpose of the Tide and Tidal Current Tables is to provide information on the timings and heights of tides as well as the speed and direction of tidal currents at specific reference stations. This data is vital for navigators and mariners as it allows them to safely plan their routes and operations in accordance with the tidal conditions. Tides can significantly affect water depths and currents, which are critical for navigation, especially in coastal and shallow water areas.

While weather forecasts, shipping news, and international regulations are important aspects of maritime operations, they are not the focus of the Tide and Tidal Current Tables. The tables serve specifically to give mariners essential tidal information that can impact their navigation decisions, ensuring safe passage and efficient operation at sea.
