219. Your vessel's drafts are: FWD 22'-03″, AFT 22'-09″; and the KG is 24.4 feet. What is the righting moment when the vessel is inclined to 15°? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)

The righting moment at a 15 heel is calculated by multiplying the vessel's displacement by the righting arm GZ. GZ is determined from the Stability Data Reference Book by subtracting KG sin θ from KN. Using the provided drafts and KG, the correct righting moment is 5,916 foot-tons.
