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?

Correct Answer: Option A — 57.5 feet

Draft corrections for trim and list are applied geometrically. At a mean draft of 60 feet with 2 feet trim by the head and 3 feet starboard list, the port aft draft calculates directly to 57.5 feet.
