Use the material in Section 1, the blue pages, of the Stability Data Reference Book. If the KG is 25.2 feet, and the drafts are: FWD 22'-03", AFT 23'-01"; at what angle will the vessel lose positive stability?
Official USCG Answer & Rule Citation
Correct Answer: Option C — 68°
Using the hydrostatic and stability data for the specified drafts and a higher KG of 25.2 feet interpolates the downing or vanishing stability angle to 68 degrees.
