Question 4630Deck General70% 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?
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.
