The sailing drafts are: FWD 24'-03", AFT 25'-03" and the GM is 5.5 feet. Use the information in Section 1, the blue pages of the Stability Data Reference Book, to determine the available righting arm at 30° inclination.

Correct Answer: Option D — 3.5 feet

Extracting data from the blue pages for drafts of 24'-03" forward and 25'-03" aft with a 5.5-foot GM requires utilizing the vessel's pre-calculated cross curves of stability. Following the 30-degree inclination ordinate against the corrected GZ curve results in a righting arm of 3.5 feet.
