Tired of searching for that air horn when “grand-pa” in his 28 foot stink boat starts heading for you while he is busy watching little Joey bounce around on the tube he is pulling at 6 knots while kicking up a 4 foot wake and making ever widening circles?
Try this 12V 118Db air horn solution:
Bad Boy Air Horn Harbor freight $39.99
Bad Boy™ Air Horn
Single push sealed start switch Tractor Supply $9.99
Conduct-Tite Starter Switch, Push Button, Sealed - 1042102 | Tractor Supply Company
X feet of wire, leads for attaching to your DC panel.
I drilled a hole in the cockpit for the switch, wired it to the DC panel and ran the wires for the air horn inside the cabin to beneath the base of the mast (deck stepped). Drilled, pushed and sealed the wires and mounted the horn to the vang on the mast foot.
Needed the horn last weekend. We all had a good laugh as 8 people in the stink boat fell out of their seats and changed their focus from little Joey to that big sailboat with the huge white sails 30 yards in front of them when grand-pa swerved.
I’ve used this air horn on my motorcycle to keep the soccer moms and high school texters at bay, works equally as well in that application.
