Question 1966Navigation General

The correct answer is A) 1.2 feet. The datum from which the predicted heights of tides are reckoned in the tide tables is the same as that used for the charts of the locality. For Hampton Roads, Virginia, the depression of the datum below mean sea level is 1.2 feet. The other answer choices are incorrect because: B) 4.1 feet is too high, C) between -.7 and +.5 feet is outside the range for Hampton Roads, and D) between 1.9 and 3.2 feet is also outside the specific value of 1.2 feet for this location.
