When operating a recreational vessel less than 39.4 feet long on federally controlled waters, a legal sound device would be a whistle. The whistle is used for warning other vessels of the operator's intentions or to signal distress. A bell is a sound device used primarily on larger vessels, a horn is typically found on powerboats and some sailboats, and a siren is not a legal sound device for recreational vessels. It's important to know and understand the appropriate sound signals to ensure safety on the water.

Bells are not a requirement for this vessel length, and sirens are typically used by emergency services. If you are operating a recreational vessel less than 39.4 feet long on federally controlled waters, the legal sound device for this vessel is a whistle or horn. A bell is not required for vessels under 39.4 feet in length. The use of a siren is generally reserved for emergency and law enforcement vessels. It is important to have a sound-producing device to signal your presence in fog and other situations where you cannot be seen.
