Having a means of audible warning sounds while traveling via boat is a requirement under international and local marine laws. A boat horn is essential for marine safety but for some reason it’s often an overlooked vessel system.

But how do you find a boat horn that has a clear sound and meets marine safety requirements? You’ll find all the information you need in today’s article.

We’ll be reviewing seven of the best boat horns you can use on almost any vessel. We’ve also provided buying information after our reviews section to assist you with your buying decision. Let’s start with why you need a boat horn. 

Why do You Need a Boat Horn?

According to the American Boating Association, all vessels bigger than 65.6ft must have a horn. Also, all recreational vessels are required to be equipped with a whistle or horn that’s audible for half a mile away. This is for safety reasons to avoid accidents with other boats on the water.

Recreational boats are required to use sound signals when there’s reduced visibility or when they’re anchored.

Navigation rules require audible sound signals to be made under certain situations such as the following:

  • At a crossing 
  • Overtaking other vessels
  • At a meeting
  • In dense fog 

Some boats come equipped with a horn but sometimes the sound of it isn’t loud enough. Other boats don’t have a horn installed. So if you have a horn that’s low quality or you don’t have one at all take a look at our seven reviews. Perhaps you’ll find a horn suitable for your boat so you can make a smart investment this year.

Buying Information

Before you can purchase one of the boat horns we’ve reviewed it’s important to know which specs and features to look at first. This next section provides buying information to help you make a decision on which boat horn is suitable for your requirements.

Suggested Type Based on Boat Size

Sound signal equipment is based on the length of your boat. You must adhere to these requirements because they were put in place for your safety.

Boats Less than 39.4 Feet in Length

A boat that is smaller than 39.4ft in length must have a loud audible device onboard for signalling. These boats must either have a whistle, air horn or bell on board to signal to other boaters, or send a message in case of an emergency. 

Boats Between 39.4 Feet and 65.6 Feet in Length 

Boats between 39.4ft and 65.6ft in length must carry a whistle & a bell. The mouth of the bell should be 7.87" in diameter and the whistle must be audible for half a nautical mile.

Loudness

Your boat horn must be audible between a half a mile and two miles away. Most importantly the larger your vessel is the louder the horn must be. For recreational boats, you must have a horn that’s between 109dB and 112dB that draws 2.5 to 5 amperes of current.

You’re allowed to use an air horn on a small boat too, provided is has the correct decibels and it’s a reliable product that won’t fail to work in emergency situations.

Power Requirements

There are different types of sound signalling devices for boats. Air horns don’t need electrical components to operate but whistles and electronic horns will need power to function. Typically boat horns require 12V DC from the boat’s battery to operate and will draw 2.5 amperes of power.

Larger horns will need at least 10 amperes of power to operate but bigger devices aren’t needed for smaller recreational boats. You simply need a horn that’s able to produce an audible sound that can be heard from half a mile away. Smaller boat horns don’t need much power to operate.

USCG Requirements

USCG stands for United States Coast Guard which is an organization that has put together boat safety rules for people to follow. Your boat horn must meet USCG requirements for it to be legal to use on your vessel.

Installation and Placement

You can purchase an OEM boat horn for the model and make of your vessel. These horns are easy to mount. Ensure your horn comes with the correct mounting and wiring components so you can connect the device to your boat’s battery successfully.

It’s ideal to place the horn in a location where it can be heard in all directions. You should install your boat horn in the front of the vessel. 

Final Thoughts

We hope that our buyer’s guide gave you the information you need to find a device suitable for your vessel. Pick one of the boat horns from our review section because all of them meet marine safety standards. But to chalk it down to the best out of all of them we recommend the Amarine Made single trumpet horn.

The Amarine Made single trumpet horn is a powerful device with robust construction. It can be used for any transportation vehicle such as SUVs, trucks and RVs. It’s easy to install and it produces a powerful 115dB of sound.
