Question 1951Navigation General

The correct answer is B) predicted in Tidal Current Tables. The velocity of the current in large coastal harbors is predicted in Tidal Current Tables published by NOAA. These tables provide detailed information on the speed and direction of tidal currents at various locations and times, which is crucial for safe navigation in these areas. The currents in coastal harbors can be quite strong and variable, so knowing the predicted current conditions is essential for captains to plan their vessel's movements and maneuvers. The other options are incorrect because: A) the currents in large harbors can be quite strong and must be accounted for, B) the currents are not generally too weak to be of concern, C) the currents are not generally constant and can change significantly with the tides, and D) the currents are predictable using the Tidal Current Tables, not unpredictable.
