BOTH INTERNATIONAL & INLAND While underway in fog you hear a rapid ringing of a bell ahead. Which vessel would this signal indicate?

Correct Answer: Option A — A vessel at anchor

Rule 35(g) mandates that a vessel at anchor must sound a rapid ringing of a bell for approximately five seconds at intervals of not more than one minute. This specific acoustic signature provides immediate notice to other mariners that a vessel is stationary and potentially obstructing the navigable channel.
