A pealess whistle that works wet and needs no power or gas, making it ideal for PFDs and paddlecraft.
Not for: Larger boats that need a louder horn to meet their sound-signal requirement.
For permanently mounted electric horn
Marinco (brand)
An established marine electrical brand whose 12V horns wire to a dash switch for instant signals.
Not for: Paddlecraft and boats with no 12V electrical system.
What the AI looks for in Boat Safety Horns
- Legal sound-signal requirement
- Under U.S. Navigation Rules, vessels under 12 m must carry some means of making an efficient sound signal. Vessels of 12 m and over need a whistle (horn) and bell meeting the rules' specifications. Required gear depends on boat length, and a horn is also needed for maneuvering and fog signals.
- Power source
- Choose between a canister air horn, a pump-refillable air horn, a 12V electric horn or a mouth whistle. Each source fails differently: canisters run empty, electric horns need power, and whistles are quieter.
- Canister condition
- Carry a spare canister and test it before each trip. Cold weather reduces output. Canisters leak down over time, often unnoticed until you need them.
- Corrosion resistance
- Mounted horns should be marine-rated with sealed or stainless housings. Salt spray quickly kills automotive horns.
Brands that matter
- Falcon Safety Products: Maker of the common Sonic Blast canister air horns.
- ECOBLAST: Pump-refillable air horns.
- Fox 40: Pealess whistles widely used in water safety.
- Marinco: Marine electrical brand that makes mounted electric horns.
- Kahlenberg: Heavy-duty marine air horns for larger vessels.
- Attwood: Broad marine hardware brand that includes horns.
What to avoid
- Relying on a single canister with no spare.
- Installing automotive horns in exposed marine locations.
- Whistles with a pea, which can jam when wet or frozen.
Questions
Is a whistle enough?
On small vessels under 12 m, a whistle can satisfy the requirement for a means of making an efficient sound signal. A horn is louder and more practical for signaling other boats.
