What sound signaling device is required for vessels 12 METERS OR MORE in length?

For vessels that are 12 meters or more in length, the regulations specify that a sound signaling device must be capable of producing an audible signal. A whistle is required because it is effective for signaling under a variety of conditions, including situations where the vessel may be navigating close to other vessels or in restricted visibility.

The requirement for a whistle aligns with international standards for sound signaling devices, emphasizing the importance of clear communication at sea. Whistles are recognized for producing a high-pitched sound that can easily carry over distances, making them suitable for alerting nearby vessels of a vessel's presence or intentions.

Other devices, while useful in certain contexts, do not meet the specific regulatory requirements for this length of vessel. For instance, while a bell, horn, or gong may also be used for signaling in some situations, they are not the mandated choice for vessels of this size. Thus, the whistle is clearly the appropriate and required sound signaling device for vessels 12 meters or more in length as per maritime regulations.
