What is the minimum sound signaling equipment required aboard a vessel 10 meters in length?

• A. A bell only
• B. A whistle only
• C. A horn only
• D. Any means of making an efficient sound signal

Answer: (D)

The fundamental idea is that any vessel must carry a working sound signaling device, not a specific type. For a vessel 10 meters long, the rule requires the ability to produce an effective sound signal, and the exact instrument isn’t fixed. A bell, a whistle, a horn, or any other device capable of making a clear, audible signal satisfies this requirement, as long as it can be used to signal properly in the conditions at hand. The key is the capability to signal efficiently, not the particular kind of device.
