Your vessel's drafts are: FWD 24'-07", AFT 25'-09"; and the KG is 23.2 feet. What is the righting moment when the vessel is inclined to 45°? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)

Correct Answer: Option D — 34,663 foot-tons

Determining displacement from the mean draft via hydrostatic tables allows calculation of GZ using KN values for a 45° angle. Subtracting KG correction and multiplying the resulting righting arm by total displacement produces 34,663 foot-tons.
