Bocinas Marinas

A marine horn is a sound-signaling device built for boats and ships, where a horn is required equipment for safe navigation rather than an upgrade. What sets it apart from a road horn is construction: marine horns use corrosion-resistant materials to survive salt air and spray. This collection runs from compact air horns for smaller vessels up to the full-size Battleship and KM-series horns used on large boats and ships.

A fog horn is a low, far-carrying horn meant to signal your position when visibility drops, which is exactly when other vessels cannot see you. Most powered boats are required to carry a sound-signaling appliance, and a dedicated marine air horn covers that role far better than a small handheld can. The larger horns here, like the Super Tooter KM-250 are built to be heard at a real distance across open water.

Yes, that is the main difference between a marine horn and a road horn. Salt air and spray corrode ordinary steel quickly, so marine horns use chrome, stainless, and treated components to hold up. The Strombos chrome nautical horns in this collection are made specifically for that exposure. If you mount any horn near the water, keep the compressor and tank in a dry, enclosed locker.

The large KM-series horns are the top of the range, built for big boats and commercial vessels that need to be heard across open water. The Destroyer KM-85 sits at the top, with the Dreadnought KM-165 close behind. For a smaller boat these are far more horn than you need, and a compact marine air horn is the sensible choice.

Match the horn to the size of the vessel and how far you need to be heard. A small runabout or pontoon is well served by a compact marine air horn, while a large boat or commercial vessel is where the KM-series horns earn their price. Whatever the size, plan the mounting around water exposure: the horn goes where it drains, and the compressor and tank go in a dry, enclosed locker.
