226. Your vessel's drafts are: FWD 27'-06″, AFT 28'-02″; and the KG is 21.3 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 15° inclination.

The righting arm at 15 inclination is 1.5 feet. This value is obtained directly from the statical stability curve (GZ curve) corresponding to the vessel's displacement and KG of 21.3 feet, as found in the Stability Data Reference Book.
