A jack-up 180 feet in length with the LCF at 120 feet AF0 has a true mean draft (draft at LCF) of 10 feet. If the trim is 3 feet by the stern, what is the draft at the stern?

Correct Answer: Option C — 11.0 feet

Draft at the stern is determined using trim, length, and LCF proportions. With LCF at 120 feet AF0 on a 180-foot vessel, the distance from LCF to the stern is 60 feet. Applying the trim ratio yields a stern draft of 11.0 feet.
