70% to pass

The SS AMERICAN MARINER has drafts of: FWD 22'-03", AFT 24'-00". Use the white pages of the Stability Data Reference Book to determine the drafts if you ballast the forepeak with 100.7 tons of seawater.

A FWD 22'-10.3", AFT 23'-06.0"
B FWD 23'-00.3", AFT 23'-05.0"
C FWD 23'-01.0", AFT 23'-05.7"
D FWD 22'-11.3", AFT 23'-04.0"
AI Explanation

The correct answer is C) FWD 23'-01.0", AFT 23'-05.7". To determine the drafts after ballasting the forepeak, we need to use the Stability Data Reference Book, which provides information on how a vessel's drafts change when weights are added or removed. By ballasting the forepeak with 100.7 tons of seawater, the forward draft increases while the aft draft decreases, resulting in the drafts shown in answer choice C. The other answer choices are incorrect because they do not accurately reflect the changes in drafts caused by the addition of 100.7 tons of seawater to the forepeak.
