Official USCG Answer & Rule Citation
Correct Answer: Option D — 10.13 feet
Aft draft is determined by adding the total trim by the stern to the observed forward draft. With a forward draft of 8.0 feet and a trim of 2.13 feet by the stern, the resulting after draft calculates directly to 10.13 feet per standard hydrostatic formulas.
