Use the material in Section 1, the blue pages, of the Stability Data Reference Book. If the KG is 24.2 feet, and the drafts are: FWD 23'-04", AFT 24'-05"; at what angle will the vessel lose positive stability?

Official USCG Answer & Rule Citation

Correct Answer: Option C — 75°

Interpolating the cross curves of stability using the mean draft from the given marks and a KG of 24.2 feet determines that positive stability ceases at 75 degrees.
