Sea-Dog Drop-In Hidden Horn V.1 w/Grills

The Sea-Dog Drop-In Hidden Horn V.1 with Grills is a compact, Coast Guard-compliant signaling device engineered for vessels under 12 meters. Built from powder-coated steel and injection-molded nylon, this drop-in horn delivers 106 decibels at 440±20 Hz—meeting COLREGS and ABYC standard A-23 requirements for legal operation on U.S. waters. The kit includes one chrome and one white decorative billet snap-in grill, allowing operators to customize appearance while maintaining acoustic performance and regulatory compliance.

Rated for 12VDC operation with NMMA Type Acceptance (#2577064), this hidden horn mounts via a 1-7/8" × 3-3/8" hole, integrating seamlessly into console or cabin installations where visibility matters. The dual-grill design lets crews swap between chrome for polished aesthetics and white for low-visibility applications—critical when signaling in crowded anchorages or during poor visibility. Powder-coated steel construction resists salt spray and UV degradation, essential for marine environments where galvanic corrosion typically attacks unpainted hardware.

This horn suits weekend anglers, commercial operators, and cruising sailors who need reliable fog signaling without permanently altering vessel profile. The drop-in design eliminates complex wiring—connection to existing 12V systems is straightforward, and the hidden mounting keeps the horn protected from weather and accidental damage during docking or rough conditions. Weekend fishermen appreciate the compact footprint and quick grill swaps; serious offshore operators rely on its regulatory certification and proven durability in salt-water exposure.
