70% to pass

The DEEP DRILLER, at a mean draft of 60 feet, has a two-foot trim by the head and a three foot list to starboard. What is the draft at the port aft draft mark?

A 57.5 feet
B 59.5 feet
C 60.5 feet
D 62.5 feet
AI Explanation

The correct answer is A) 57.5 feet. The reasoning is as follows: - With a mean draft of 60 feet and a 2-foot trim by the head, the draft at the forward draft mark is 62 feet. - Since the vessel has a 3-foot list to starboard, the draft at the port aft draft mark will be 3 feet less than the mean draft, which is 57 feet. The other options are incorrect because: B) 59.5 feet is too high for the port aft draft mark given the 3-foot list to starboard. C) 60.5 feet is too high for the port aft draft mark given the 2-foot trim by the head. D) 62.5 feet is the draft at the forward draft mark, not the port aft draft mark.
