Question 2549 Deck Safety

The correct answer is A) Available GM 3.5 ft. To determine the available GM (Metacentric Height), you need to use the stability data provided in the table ST-0139 and refer to the white pages of The Stability Data Reference Book. Based on the information given, the available GM is 3.5 ft. The other options are incorrect because they do not match the value obtained from the stability data and the Stability Data Reference Book. Option B (3.9 ft), C (4.3 ft), and D (4.8 ft) are not the correct available GM for the given load condition of the SS AMERICAN MARINER.
