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)
Official USCG Answer & Rule Citation
Correct Answer: Option D — 34,663 foot-tons
Calculate mean draft to identify the vessel's displacement from the hydrostatic tables. Locate the GZ value for a 45-degree heel at the given KG. Multiplying the displacement by the corrected GZ value provides the righting moment of 34,663 foot-tons, consistent with standard naval architecture stability data.
