Requirement to Have Sound-Producing Devices
Sound-producing devices are essential when visibility is limited. Paddlers also use sound signals to let other boaters know what they plan to do.
- A whistle and a small horn are common sound-producing devices. In certain coastal waters, you also may want to carry a larger foghorn.
- On federally controlled waters, vessels less than 65.6 feet (20 meters) in length, which includes paddlecraft, are required to carry on board a whistle or horn or some other means to make an efficient sound signal audible for at least one-half mile.
- Check with your state’s boating agency for any specific requirements for sound-producing devices.
