Safety & Environmental Protection (Deck) USCG Question #2969 (Set 85)

The static stability curve for a given vessel peaks at 34°. For this ship, the danger angle for a permanent list would be about __________.

Official USCG Answer & Rule Citation

Correct Answer: Option B — 17°

The danger angle for a permanent list is generally considered to be half the angle of maximum righting arm on the static stability curve. Since the curve peaks at 34 degrees, the vessel's ability to resist further heeling is significantly compromised beyond 17 degrees, marking the threshold for potential capsizing.
