Question 1942Navigation General70% to pass
Where will you find information about the duration of slack water?
AI Explanation
The correct answer is B) Tidal Current Tables.
The Tidal Current Tables, published by the National Oceanic and Atmospheric Administration (NOAA), provide information on the duration and timing of slack water, which is the period of little or no tidal current. This information is crucial for safe navigation, as it helps mariners plan their vessel's movements around the tidal cycle.
The other options are not the correct sources for information on the duration of slack water. The American Practical Navigator (A) and Sailing Directions (C) do not specifically focus on tidal current data, while Tide Tables (D) provide information on the timing and heights of tides, but not the duration of slack water.
