70% to pass

Your vessel's drafts are FWD 20'-08", AFT 23'-00". Use the information in Section 1, the blue pages, of the Stability Data Reference Book to determine the final drafts if 195 tons of cargo are discharged 76 feet aft of amidships.

A FWD 20'-05", AFT 21'-11"
B FWD 20'-07", AFT 22'-01"
C FWD 20'-11", AFT 22'-00"
D FWD 21'-03", AFT 22'-04"
AI Explanation

The correct answer is C) FWD 20'-11", AFT 22'-00". To determine the final drafts, we need to calculate the change in drafts due to the discharge of 195 tons of cargo 76 feet aft of amidships. Using the information provided in the Stability Data Reference Book, Section 1 (the blue pages), we can calculate the change in drafts. The decrease in draft forward is 3 inches, and the decrease in draft aft is 12 inches. Therefore, the final drafts are FWD 20'-11" and AFT 22'-00". The other options are incorrect because they do not accurately reflect the change in drafts based on the given information.
