Question 2451 Deck Safety

70% to pass

The SS AMERICAN MARINER is ready to bunker with drafts of FWD 17'-05", AFT 19'-07". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0175 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 D) 0.99 foot. To determine the free surface correction, we need to use the white pages of The Stability Data Reference Book and the given draft information. The free surface correction is based on the total free surface moment, which is calculated using the tank sizes and free surface factors. Given the drafts of 17'-05" forward and 19'-07" aft, the free surface correction can be looked up in the reference book and is determined to be 0.99 foot. The other options are incorrect because they do not match the value provided in the reference book for the given tank configuration and drafts.
