In fog, a 25 meter vessel that is anchored must

• A. rapidly ring her bell for 5 seconds at intervals of no more than 1 minute.
• B. sound two short blasts every minute.
• C. shine a white light every 30 seconds.
• D. sound one prolonged blast every two minutes.

Answer: (A)

In restricted visibility, vessels use specific sound signals to convey their status. For a vessel that is anchored, the standard signal is to ring a bell for five seconds at intervals of no more than one minute. This audible cue tells other ships that you’re stationary and anchored, helping to prevent collisions in fog. The other options don’t match the anchored signal pattern: two short blasts per minute isn’t the prescribed signal for an anchored vessel, shining a white light every 30 seconds isn’t a recognized fog signal, and one prolonged blast every two minutes isn’t the anchored signal either. If it’s nighttime, you would also observe the appropriate lights, but the bell signal specifically communicates anchoring in restricted visibility.
