The draft at the forward draft mark of a jack-up is 11 feet 3 inches while the draft at the aft draft mark is 12 feet 9 inches. The value of trim is __________.

Correct Answer: Option B — 1 foot 6 inches to the stern

Trim is defined mathematically as the arithmetic difference between the forward draft and the aft draft. Subtracting an aft draft of 12 feet 9 inches from a forward draft of 11 feet 3 inches yields a net trim of 1 foot 6 inches to the stern.
