Question 2558 Deck Safety

The correct answer is A) Available GM 2.8 ft. This is determined by using the information provided in the table ST-0081 and referencing the white pages of The Stability Data Reference Book, which contain stability curves and other relevant data for the SS AMERICAN MARINER. Based on the loading condition in the table, the available GM (Metacentric Height) is 2.8 feet, as indicated in the stability data. The other answer choices are incorrect because they do not match the available GM value obtained from the stability reference material for the given loading condition of the vessel.
