The sailing drafts are: FWD 23'-02", AFT 24'-06" and the GM is 2.8 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 B — 2.5 feet

Cross-reference the vessel's mean draft derived from the forward and aft drafts against the blue pages data, applying the 2.8 feet GM to extract the correct righting arm value of 2.5 feet at 30 degrees inclination.
