Question 1945Navigation General

The correct answer is A) Tidal Current Tables. Tidal Current Tables provide detailed data on the direction and velocity of rotary tidal currents, which are the key information needed to understand and navigate tidal currents. Tide Tables, on the other hand, focus on the rise and fall of tides, but do not contain the specific current data. The Nautical Almanac and Mariner's Guide do not contain the comprehensive current information found in the Tidal Current Tables. Therefore, Tidal Current Tables are the primary reference source for data on the direction and velocity of rotary tidal currents, making option A the correct answer.
