138. Tour vessel's drafts are: FWD 22'-09″, AFT 23'-07″; and the KG is 24.2 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 18° inclination.

The righting arm at 18 inclination is determined by referencing the vessel's stability curves in the Stability Data Reference Book, using the given drafts and KG of 24.2 feet to find the corresponding displacement, which yields a righting arm of 0.7 foot.
