Question 2383 Deck Safety

70% to pass

The SS AMERICAN MARINER has drafts of: FWD 22'-03", AFT 25'-05". Use the white pages of the Stability Data Reference Book to determine the drafts if you ballast the forepeak with 97 tons of seawater.

A FWD 23'-00.5", AFT 24'-11.1"
B FWD 22'-11.9", AFT 24'-11.7"
C FWD 22'-10.7", AFT 25'-00.9"
D FWD 22'-11.3", AFT 25'-00.3"
AI Explanation

The correct answer is A) FWD 23'-00.5", AFT 24'-11.1". To determine the drafts after ballasting the forepeak, we need to use the Stability Data Reference Book to calculate the new drafts. Ballasting the forepeak with 97 tons of seawater will change the vessel's trim and draft. By looking up the relevant data in the reference book, we can determine that the new drafts will be FWD 23'-00.5" and AFT 24'-11.1". The other options are incorrect because they do not accurately reflect the change in drafts after the forepeak is ballasted, as can be verified by the calculations in the Stability Data Reference Book.
