The sailing drafts are: FWD 16'-06", AFT 17'-04" and the GM is 2.6 feet. Use the information in Section 1, the blue pages, of the Stability Data Reference Book, to determine the available righting arm at 15° inclination.

Correct Answer: Option B — 0.8 foot
Calculate the mean draft to determine the correct stability curve page. Using the Stability Data Reference Book, locate the curve for the calculated mean draft. At 15 degrees, the righting arm (GZ) is derived by applying the GM correction to the cross curves of stability as per standard naval architecture practices.
