The sailing drafts are: FWD 25'-03", AFT 26'-03" and the GM is 3.5 feet. Use the information in Section 1, the blue pages, of the Stability Data Reference Book, to determine the available righting arm at 25° inclination.
AI Explanation
The correct answer is C) 2.0 feet.
According to the information provided, the vessel has a forward draft of 25'-03", an aft draft of 26'-03", and a GM (metacentric height) of 3.5 feet. Using this data and referring to the Stability Data Reference Book, section 1 (the blue pages), the available righting arm at 25° inclination is 2.0 feet.
The other options are incorrect because they do not match the value indicated in the Stability Data Reference Book for the given vessel characteristics and angle of inclination.
