Your vessel's drafts are: FWD 22'-03", AFT 22'-09"; and the KG is 23.2 feet. What is the righting moment when the vessel is inclined to 30°? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)

Correct Answer: Option C — 25,520 foot-tons

Using hydrostatic data corresponding to the given drafts yields vessel displacement. Extracting KN for 30° and subtracting the vertical center of gravity effect (KG sinθ) provides GZ. Multiplying GZ by displacement results in 25,520 foot-tons.
