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)

Correct Answer: Option B — 8,666 foot-tons
Mean draft is 25'-02". Extract displacement from the hydrostatic data. Using the stability curves for a KG of 24.0 feet, find the GZ at 15 degrees. Multiplying displacement by the GZ value results in 8,666 foot-tons, confirming the vessel's stability performance at this specific draft and KG.
