- Q131 - Deck Safety: Stability Problems
124. 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.
The righting arm at a 15 inclination is calculated using the formula GZ = GM x sin θ, where GM is 2.6 feet. Substituting these values yields GZ ≈ 0.7 feet, and the closest answer choice is 0.8 feet.
