Our Verdict
Every boat is legally required to carry a sound-producing device. A marine air horn from West Marine is the simplest, most affordable way to comply — and it's loud enough to actually get attention in an emergency.

Legal Requirement
Federal law requires all boats 16 feet and over to carry an approved sound-producing device. Boats under 16 feet must be able to make an efficient sound signal. An air horn satisfies both requirements and costs less than $25.
When You Need It
Air horns are used to signal your presence in fog, alert other vessels of your intentions, and call for help in an emergency. The standard distress signal is three short blasts. Know the signals before you need them.
