Safety & Environmental Protection (Deck) USCG Question #3108 (Set 87)

Your vessel's drafts are: FWD 18'-03", AFT 18'-09"; and the KG is 22.6 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the angle of list if the center of gravity is shifted 1.4 feet off the centerline.

Official USCG Answer & Rule Citation

Correct Answer: Option B — 22°

The angle of list is determined by the formula tan(theta) = (Shift of G) / (GM). Using the stability curves for the mean draft of 18'-06" and KG of 22.6 feet, find the KM to calculate GM. Applying the shift of 1.4 feet results in a 22-degree list.
