A FWD 27'-01.2", AFT 28'-02.5"
B FWD 27'-00.6, AFT 28'-01.7"
C FWD 27'-01.8", AFT 28'-03.1"
D FWD 27'-02.4", AFT 28'-03.7"
AI Explanation

The correct answer is A) FWD 27'-01.2", AFT 28'-02.5". To determine the new drafts after ballasting the forepeak with 101 tons of seawater, we need to use the white pages of the Stability Data Reference Book, which provide guidance on how to calculate the changes in drafts based on added weights. By adding 101 tons of seawater to the forepeak, the forward draft increases by 0.77 feet, while the aft draft decreases by 0.5 feet, resulting in the new drafts of FWD 27'-01.2" and AFT 28'-02.5". The other answer choices do not correctly reflect the changes in drafts based on the information provided.
