On boats, primary and backup signals are incredibly important. Air horns are usually forgotten when it comes to a boat’s safety system. It’s always a great idea to stay prepared for emergencies so we’ve detailed what you should look out for when buying a boat air horn.
When selecting a boat air horn, think about the sound output and range. The horn should be loud enough to be heard over long distances, especially in noisy or adverse conditions. Look for horns with a decibel (dB) rating suitable for marine environments, typically ranging from 100dB to 130dB.
Before purchasing a boat air horn, verify that it complies with relevant regulations and standards, such as those set by the United States Coast Guard (USCG) or the International Maritime Organization (IMO). You can also check your local or state regulations regarding the type of horn required or recommended for your vessel. Some areas may have specific requirements for sound level and the type of horn.
A boat air horn should be constructed from durable materials capable of withstanding harsh marine conditions, including exposure to saltwater and UV radiation. Opt for horns made from corrosion-resistant metals like stainless steel or marine-grade plastics. Check for waterproof seals and sturdy mounting hardware to ensure longevity and reliability.
Just like car horns, boat air horns are used to signal warnings. They can alert nearby vessels of your presence, especially in situations where visual signals aren’t an option, like in foggy conditions or at night. In busy waterways, boats often encounter each other, and having a loud horn can help avoid collisions by alerting other vessels to your presence. In emergencies, such as when a boat is in distress or requires immediate assistance, the air horn can be used to attract attention and signal for help. Overall, boat air horns are essential safety equipment to have onboard.
Air horns work by releasing compressed air through a horn-shaped device, creating a loud sound. The compressed air is typically stored in a tank and released when the horn button is pressed.
Air horns can be extremely loud, often reaching sound levels of 120 decibels or more. This is significantly louder than a typical car horn, which usually produces around 100 decibels.
A disposable air horn can have a shelf life of up to 10 years, but always check the can to see if it has a different amount of time on it.
Maintenance for air horns typically involves keeping the compressor and air tank clean and free of debris, checking for leaks in the air lines, and ensuring that the horn itself is in good condition. It's also important to regularly check the pressure in the can to see if the horn is functional.
