What sound safety device needs to be on a vessel under 16 feet?

For vessels that are under 16 feet, the law requires that they carry a sound signaling device to ensure safety on the water. Specifically, a hand, mouth, or power whistle is deemed appropriate for this size of the vessel. This requirement is in place because, in a smaller craft, quick and effective communication can be essential, particularly in situations where visibility is compromised or when alerting other boats to your presence is necessary.

A hand or mouth whistle is effective for signaling as it is portable, easy to use, and can produce a loud, clear sound. A power whistle is also a viable option, offering a solution that does not require physical effort to operate, which can be important in emergencies.

The other options may not fulfill the regulations for sound signaling devices on smaller vessels. For instance, a bell is typically used on larger vessels where it can be more easily heard over greater distances, and a fog horn is more suited for larger ships needing to signal in low visibility conditions. A power whistle specifically is aligned with the legal requirements for vessels under 16 feet, making this choice the correct one.
