415. Your vessel's drafts are: FWD 24'-07″, AFT 25'-09″; and the KG is 24.0 feet. What is the righting moment when the vessel is inclined to 15°? (Use the selected stability curves in Section 1, the blue pages, of the Stability Data Reference Book)

The righting moment is calculated by multiplying the vessel's displacement by the righting arm (GZ) at a given heel angle. Using the Stability Data Reference Book, with a mean draft derived from the forward and aft drafts, and a KG of 24.0 feet, yields a righting moment of 8,666 foot-tons.
