70% to pass

Your vessel's drafts are FWD 19'-03", AFT 21'-07". Use the information in Section 1, the blue pages, of the Stability Data Reference Book to determine the final drafts if 142 tons of fuel are pumped 86 feet aft.

A FWD 19'-00", AFT 21'-08"
B FWD 19'-01", AFT 21'-04"
C FWD 18'-09", AFT 22'-01"
D FWD 19'-00", AFT 21'-01"
AI Explanation

The correct answer is C) FWD 18'-09", AFT 22'-01". To determine the final drafts, we need to use the information provided about the vessel's initial drafts and the change in weight distribution due to the fuel transfer. Based on the given data, moving 142 tons of fuel 86 feet aft will change the vessel's trim, resulting in a forward draft of 18'-09" and an aft draft of 22'-01". The other options are incorrect because they do not correctly account for the change in trim caused by the fuel transfer. For example, option A maintains the same aft draft, which is not possible given the shift in weight distribution.
