Collection: Hailer Horns

Hailer horns and PA speaker horns serve distinct roles on board, from projecting instructions to crew or nearby vessels to routing audio from a VHF radio's hailer output. The selection spans compact weatherproof units from Speco Tech in sizes from 4x6 inches up to 8.5 inches, weather-resistant aluminum horns for saltwater conditions, and deck horns from Newmar Power in a tiered range of wattage ratings. Shakespeare and Standard Horizon round out the lineup with hailer solutions that include mounting hardware and, in some models, talkback capability.

Before choosing, match the horn's impedance (4 ohm or 8 ohm) to your radio, amplifier, or intercom output, then confirm the wattage suits your vessel. For exposed installations, weigh aluminum versus weatherproof plastic construction based on your environment. Transformer-equipped Speco models can simplify wiring in certain setups. If pairing a horn with a VHF radio, the Standard Horizon 240SW is built for that integration. Swivel brackets on some Shakespeare units let you direct sound precisely, while Newmar's PA series gives you a clear path to right-sizing the horn for your boat.
