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.
