BOTH INTERNATIONAL & INLAND You are on watch in fog. Which vessel is "in sight"?
Official USCG Answer & Rule Citation
Correct Answer: Option A — A vessel that you can see from the bridge
Rule 3(k) defines vessels as being "in sight of one another" only when one can be observed visually from the other. Hearing a fog signal or detecting a target on radar does not satisfy this strict visual observation requirement.
