Question 2006Navigation General

The correct answer is C) the difference between the depth of the water and the area's tidal datum. The height of tide refers to the vertical distance between the water level at a specific time and the area's tidal datum, which is a reference point used to measure water levels. The tidal datum is established by the National Oceanic and Atmospheric Administration (NOAA) and serves as the standard for measuring tidal heights. The other options are incorrect because they do not accurately define the height of tide. Option A refers to the depth of the water, not the tidal height. Option B describes the difference between high and low tide levels, which is not the same as the height of tide. Option D is also incorrect, as it only describes the depth of water at a specific time, without considering the tidal datum.
