The COASTAL DRILLER has a change of trim by the head of 2.0 feet. What is the change of draft at the forward draft marks?

Correct Answer: Option C — 1.33 feet

Change in draft at any perpendicular depends on the ship's center of flotation (LCF). For a uniform change of trim assuming LCF amidships, a 2.0-foot trim change by the head results in a forward draft change equal to two-thirds of the total, or 1.33 feet.
