70% to pass

The SS AMERICAN MARINER has drafts of: FWD 15'-06", AFT 18'-06". Use the white pages of the Stability Data Reference Book to determine the drafts if you ballast the forepeak with 62 tons of seawater.

A FWD 16'-00.1", AFT 18'-02.1"
B FWD 15'-11.5", AFT 18'-02.7"
C FWD 16'-01.3", AFT 18'-00.9"
D FWD 16'-00.7", AFT 18'-01.5"
AI Explanation

The correct answer is D) FWD 16'-00.7", AFT 18'-01.5". To determine the new drafts after ballasting the forepeak with 62 tons of seawater, we need to use the Stability Data Reference Book to calculate the change in drafts. Ballasting the forepeak adds weight forward, causing the bow to sink deeper and the stern to rise. The Stability Data Reference Book provides the necessary information to quantify these changes and arrive at the new drafts. The other answer choices are incorrect because they do not accurately reflect the changes in draft resulting from the 62 tons of ballast added to the forepeak.
