70% to pass

The SS AMERICAN MARINER is ready to bunker with drafts of FWD 21'-04", AFT 26'-04". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0177 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction.

A 0.62 foot
B 0.80 foot
C 0.85 foot
D 0.99 foot
AI Explanation

The correct answer is A) 0.62 foot. To determine the free surface correction, you need to use the white pages of The Stability Data Reference Book and the given tank soundings. Based on the provided drafts of FWD 21'-04" and AFT 26'-04", the free surface correction is 0.62 foot, as indicated in the reference book. The other options are incorrect because they do not match the value found in the reference book for the given tank soundings and drafts. The free surface correction is a specific calculation based on the tank configurations and fluid levels, and the reference book provides the accurate value in this case.
