For a vessel 12 meters or more, in addition to a whistle, what must be carried?

• A. Horn
• B. Bell
• C. Flares
• D. Bell and Gong

Answer: (A)

When a vessel is 12 meters or longer, the signaling requirement calls for a more audible sound device than a whistle alone. A horn provides a louder, longer-range signal, which is important in busier waterways, spaces with engine noise, or poor visibility. The combination ensures other vessels can hear you from a greater distance, improving safety. Flares are distress signals and not the direct substitute for a larger air-powered signal, and bells or gongs aren’t the mandated addition for this size. So the horn is the best fit to meet the requirement in addition to the whistle.
