Horns – an audible signaling device for a boat
In the Horns product group you will find both electric and mechanical signaling devices: a 12V electric horn made of stainless steel, a Marco Shark horn, a Tremi signal/fog horn, a Seaworld dual-model stainless steel horn, and a larger Seaworld EMX2 400mm model, as well as a 42cm fog horn that can be used by blowing without an electrical connection.
International maritime regulations (COLREG) require a boat to have a sound signal device that can give audible signals, for example in fog or when overtaking – an electric horn gives a louder and more consistent sound than an inflatable fog horn, but the inflatable model also serves as a reliable backup system when the boat's electricity is out of service.
Larger models (such as the EMX2 400mm) are longer and are especially suitable for larger boats or busy waterways, while the more compact model is sufficient for smaller boats. Test the horn function regularly during the season and check the condition of the electrical connections for corrosion, as the horn is a safety device that must operate immediately if necessary.
An electric horn is much more convenient to use than an inflatable model, as it works with a single press without any physical effort – this is especially important in an emergency, where quick and repeated signaling can be crucial. Stainless steel models (such as Seaworld's dual model) are more resistant to saltwater corrosion than plastic-bodied options and maintain their sound quality for longer when used outdoors.
Place the horn as high and unobstructed as possible so that the sound travels as far and wide as possible without being muffled by the mast or cockpit structures. Check the tightness of the connections on an electric model regularly – poor grounding or an oxidized connector can significantly reduce the sound volume just when it is needed most.
Check the official requirements for your local water area and boat class for a sounder before purchasing, as requirements may vary depending on the size and area of ??use of the boat. Seaworld and Marco's ranges cover both smaller and larger boat sizes, so choose the power according to the size class of your own boat.
Remember to also check the tightness of the horn's attachment mechanically, as a loosely attached horn can vibrate and become damaged in rough seas over time.
The volume of an electric model is usually sufficient for larger boats, but always check local requirements for your boat size class.
The audible range of the signaling device varies depending on the weather and wind, so in strong winds or rain it is advisable to use the horn more often than in calm weather.
