Using the information in Section 1, the blue pages, of the Stability Data Reference Book, determine the danger angle for permanent list if the KG is 23.7 feet and the drafts are: FWD 28'-00", AFT 28'-06".

Correct Answer: Option B — 21°

Entering the Stability Data Reference Book blue pages with the specified mean draft and KG values, cross-referencing deadweight and displacement parameters yields a critical danger angle for permanent list of 21 degrees, ensuring safe operational limits are maintained.
