A FWD 22'-10.5", AFT 26'-00.4"
B FWD 22'-09.3", AFT 26'-01.6"
C FWD 22'-09.9", AFT 26'-01.0"
D FWD 22'-08.7", AFT 26'-02.2"
AI Explanation

The correct answer is A) FWD 22'-10.5", AFT 26'-00.4". To determine the new drafts, we need to use the white pages of the Stability Data Reference Book, which provide tables to calculate the changes in draft due to adding or removing weights. By adding 77 tons of seawater to the forepeak, the forward draft increases, and the aft draft decreases, resulting in the drafts provided in answer choice A. The other options are incorrect because they do not accurately reflect the changes in draft based on the information provided and the use of the Stability Data Reference Book.
