A FWD 28'-06.3", AFT 28'-08.0"
B FWD 28'-07.3", AFT 28'-07.8"
C FWD 28'-10.0", AFT 28'-08.0"
D FWD 28'-06.2", AFT 28'-06.2"
AI Explanation

The correct answer is B) FWD 28'-07.3", AFT 28'-07.8". To determine the drafts after ballasting the forepeak, we need to use the principles of stability and the information provided in the Stability Data Reference Book. The change in draft due to adding 81.05 tons of seawater to the forepeak can be calculated using the displacement and the waterline length of the vessel. The other options are incorrect because they do not accurately reflect the change in draft based on the given information and the principles of stability.
