What is the trim of a jack-up with a forward draft of 12 feet and an after draft of 13 feet?
AI Explanation
The correct answer is A) 1.0 foot by the stern.
The trim of a vessel is the difference between the forward and aft drafts. In this case, the forward draft is 12 feet and the aft draft is 13 feet, resulting in a trim of 1.0 foot by the stern.
The other options are incorrect because:
B) 0.5 foot by the stern is too small, as the difference between the drafts is 1.0 foot.
C) 0.5 feet by the head is incorrect, as the vessel has a trim by the stern, not by the head.
D) 2.0 feet by the stern is too large, as the difference between the drafts is only 1.0 foot.
