Powerful Dual Marine Horn 12V – Chromed Twin Trumpet

This powerful dual horn gives your boat a voice that won’t go unnoticed. Its loud, dual-tone blast fills the air and cuts through ambient noise – a vital feature when you’re boating in low-visibility conditions or need to alert another vessel of your presence. Thanks to the twin combination of low and high pitch, the sound signal covers a wide frequency range and is better perceived by the human ear, especially against background wind and engine noise. This makes audible communication (navigation signals for turning, approaching, fog, etc.) more effective and safe. The horn’s construction is made with the marine environment in mind: the ABS body won’t corrode or resonate excessively, and its chrome finish reflects sunlight and protects the plastic from UV aging. The stainless steel bracket holds the two trumpets firmly – even when pounding through waves at sea, the horn remains stable and doesn’t produce rattle or unwanted vibration. Mount the horn in an open, elevated spot on your boat (for example, atop the wheelhouse or on a mast arch) for maximum sound dispersion. Its electrical hookup is standard – it can be operated by a button or switch on your console, and it’s advisable to use a relay to protect the circuit and ensure full current delivery. When pressed, the horn gives an instantaneous sound response, as the diaphragms in the trumpets generate a rich tone comparable to that of larger ship horns. With this upgrade, your boat not only meets the requirements for sound signaling, but also showcases a finished, professional appearance. Every time you use the horn – whether it’s a salute to a friend at the marina or a serious navigation alert – you can count on its strength and clarity.

• Typical uses: Serves as the primary sound signaling device for boats and yachts – used for the required navigation signals during maneuvers (e.g., overtaking, approaching in obscured visibility, at anchor in fog). Extremely useful in dense fog or at night to warn other vessels of your location. It can also be used as a warning to swimmers or small craft ahead of you in the water. Additionally, many captains use it traditionally when leaving or entering a harbor as a greeting or cautionary blast.
• Suitable vessels: Suitable for most types of boats equipped with a 12V system – motor yachts, sailing yachts, fishing boats, recreational cruisers, RIBs, and even larger rigid inflatables that have a place to mount it. On sailboats, it’s often mounted on the mast or the spreader frame, whereas on powerboats – on the cabin roof or bow radar arch. For vessels over ~20 meters, it can serve as an auxiliary horn (large ships often have air horns), but for small to mid-sized craft this will be the main source of sound signals.
• Installation and operation tips: Choose a location where the two trumpets have clear space in front of them – point them forward, slightly upward, to carry sound over obstacles. Ensure the mounting surface is flat and sturdy; use rubber gaskets (if provided) under the bracket to dampen vibrations and seal the screw holes. Wire the horn to your existing horn button on the console (or install one if absent) using an appropriately rated relay – this will protect the switch and your boat’s electronics from the high current surge. Use sufficiently gauged wires (the horn draws 16A) and properly insulate all connections against moisture. For maintenance, periodically rinse the trumpets inside with fresh water to remove salt deposits – you can flush them when the boat is on land and let them dry out. Check the terminals and wiring for corrosion, especially if the horn is mounted in the open; if needed, apply a thin coat of dielectric grease on the contacts for protection. With correct installation and care, this horn will serve you reliably for years, providing safety and a prestigious look for your vessel.
