Question 2456 Deck Safety

70% to pass

The SS AMERICAN MARINER is ready to bunker with drafts of FWD 11'-01", AFT 15'-01". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0086 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction.

A 0.68 foot
B 0.85 foot
C 0.97 foot
D 1.30 feet
AI Explanation

The correct answer is A) 0.68 foot. To determine the free surface correction, we need to use the white pages of The Stability Data Reference Book. Based on the given drafts of FWD 11'-01" and AFT 15'-01", we can calculate the ship's mean draft and displacement from the appropriate tables or curves. Using the information provided in the table ST-0086, we can then determine the free surface correction, which is 0.68 foot. The other options are incorrect because they do not match the value calculated using the Stability Data Reference Book for the given conditions.
