BOTH INTERNATIONAL & INLAND You are underway in fog when you hear the rapid ringing of a bell for five seconds followed by the sounding of a gong for five seconds. What does this signal indicate about the vessel?

Correct Answer: Option A — More than 100 meters in length, at anchor

Rule 35(g) mandates that a vessel of 100 meters or more in length at anchor shall sound the bell for five seconds forward, followed by the gong for five seconds aft. This specific signal is required to indicate the vessel's length and status in restricted visibility.
