70% to pass

The SS AMERICAN MARINER has the following drafts: FWD 09'-00", AFT 15'- 11.5". Upon completion of loading and bunkering the items shown in table ST-0021 below will be on board. Use the white pages of The Stability Data Reference Book to determine the minimum GM required to meet a one compartment standard.

A 1.80 feet
B 1.89 feet
C 2.05 feet
D 1.98 feet
AI Explanation

The correct answer is D) 1.98 feet. To determine the minimum GM (Metacentric Height) required to meet a one compartment standard, you need to use the stability data and calculations in The Stability Data Reference Book. Based on the provided drafts (Forward 9' and Aft 15' 11.5") and the loading information in table ST-0021, the reference book would provide the necessary calculations to arrive at the minimum GM of 1.98 feet to meet the one compartment standard. The other options are incorrect because they do not match the value calculated using the stability data and methods prescribed in the reference book for the given vessel and loading condition.
