Safety & Environmental Protection (Deck) USCG Question #2554 (Set 77)

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.

Official USCG Answer & Rule Citation

Correct Answer: Option C — 2.0 feet

Using Section 1 blue pages data for sailing drafts of 25'-03" forward and 26'-03" aft with a 3.5-foot GM involves applying cross curves of stability and hydrostatic corrections. Projecting the plotted values to a 25-degree heel angle determines an exact righting arm of 2.0 feet.
