Question 1842Navigation General

The correct answer is A) 39 feet (11.9 meters). The depth of the water beneath your keel can be calculated by adding the charted depth (8 fathoms) and the height of tide (-4.0 feet) and subtracting the draft of the vessel (5.0 feet). 8 fathoms = 48 feet, plus the -4.0 feet of tide equals 44 feet. Subtracting the 5.0 foot draft gives a depth of 39 feet beneath the keel, which is the correct answer. The other options are incorrect because they do not properly account for the charted depth, tide height, and vessel draft in the calculation.
