In fog, three distinct bell strokes followed by five seconds of rapid bell ringing followed by three distinct bell strokes indicates a vessel ________.

• A. Aground
• B. Not under command
• C. Under way
• D. Anchored

Answer: (A)

In fog, vessels use bell signals to communicate their status, and certain patterns are a fixed language. The sequence of three distinct bell strokes, then five seconds of rapid bell ringing, followed by three more bell strokes is the standardized signal indicating a vessel is aground. The extended rapid ringing emphasizes the urgent condition, and the final three strokes confirm the message. When you hear this pattern, you should treat the other vessel as unable to move because it’s grounded and take action to avoid a collision. Other statuses have different signal patterns and do not match this specific bell sequence.
