Your vessel's drafts are: FWD 14'-11", AFT 16'-01"; and the KG is 24.4 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 D — 18,240 foot-tons

Entering the stability tables with forward and aft drafts provides displacement and KN values for 30° heel. Applying the KG correction yields the righting arm GZ, which when multiplied by displacement yields 18,240 foot-tons.
