Question 1413Navigation General

The correct answer is A) Tidal Current Tables. Tidal Current Tables provide detailed information about the direction and velocity of rotary tidal currents, which are currents that flow in a circular pattern due to the interaction of the earth's rotation and the tidal forces. This information is critical for mariners to plan their routes and understand how the currents will affect their vessel's movement. The other options are incorrect because they do not specifically contain the detailed tidal current information needed. The Nautical Almanac provides astronomical data, Tide Tables provide information on water levels, and the Mariner's Guide is a general reference work, but none of these contain the specific tidal current data found in the Tidal Current Tables.
