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 __________.
β’ Trim is the difference between the aft draft and forward draft. β’ Convert all drafts to the same unit (inches or feet) before comparing. β’ A positive trim "to the stern" means the aft draft is deeper than the forward draft.
β’ How many total inches are in 11 feet 3 inches and in 12 feet 9 inches? β’ What is the numerical difference between these two draft values once they are in the same unit? β’ If the aft draft is larger than the forward draft, in which direction is the vessel trimmed?
β’ Be sure both drafts are converted into the same unit before subtracting. β’ Check that you subtract forward draft from aft draft to get trim to the stern. β’ After finding the difference, convert back to feet and inches to match the answer choices.
