Safety & Environmental Protection (Deck) USCG Question #3062 (Set 86)

The sailing drafts are: FWD 23'-10", AFT 25'-02" and the GM is 5.3 feet. Use the information in Section 1, the blue pages, of the Stability Data Reference Book, to determine the available righting arm at 18° inclination.

Official USCG Answer & Rule Citation

Correct Answer: Option D — 1.9 feet

Find the mean draft and reference the corresponding stability curve in the blue pages. At 18 degrees, the righting arm is determined by applying the vessel's specific GM to the cross curves. This ensures compliance with stability documentation requirements for assessing the righting moment at various angles of heel.
