Question 2587 Deck Safety

The correct answer is A) 2.05 feet. To determine the minimum GM (metacentric height) required to meet a one-compartment standard, the stability data in the white pages of The Stability Data Reference Book must be used. Given the drafts of the SS AMERICAN MARINER (FWD 8'-11.5", AFT 15'-11.5") and the loading information provided in table ST-0138, the minimum GM required is 2.05 feet to meet the one-compartment standard. The other options are incorrect because they do not accurately represent the minimum GM required based on the provided information and the stability data in the reference book.
