Why Boat Horns Are Essential
Boat horns are a vital part of your onboard safety system and are required under federal navigation laws. Every vessel must carry a sound-producing device capable of signaling intentions or emergencies.
At Wholesale Marine we stock electric horns, air horns, compressed-air systems, and compact horns for smaller boats - each designed for dependable performance on the water.
Benefits of a Reliable Marine Horn
- Ensures you're heard in crowded waterways or fog.
- Provides a quick and clear method to signal danger or intent.
- Designed to withstand corrosion, vibration, and salt exposure.
How to Choose the Right Boat Horn
- Match to Vessel Size - Boats under 39 ft need a horn audible from at least 1/2 mile away.
- Select Power Type - Choose electric horns for compact installs or air horns for maximum volume.

Frequently Asked Questions About Boat Horns
What type of boat horn do I need for my vessel?
Choose based on your boat's length and setup. Smaller boats use electric or handheld horns; larger vessels often require dual-tone or compressor-driven systems.
Are boat horns required by the U.S. Coast Guard?
Yes. All boats must carry a sound-producing device capable of signaling danger or intent - such as a horn or whistle
How loud should a boat horn be?
Your horn should produce an audible signal for at least half a mile in clear conditions.
Can I use a car horn on my boat?
