Question 2571 Deck Safety

The correct answer is B) Available GM 4.16 ft. To determine the available GM, you need to refer to the Stability Data Reference Book and use the white pages that contain the stability data for the specific vessel, in this case, the SS AMERICAN MARINER. By looking up the load condition in the table provided, you can find the corresponding GM value, which is 4.16 ft. The other options are incorrect because they do not match the GM value listed in the Stability Data Reference Book for the given load condition of the SS AMERICAN MARINER.
