Last year I was out in the fog when my bass horn failed on my cheap electric horn. I sounded like the roadrunner (beep-beep) when my foghorn sounded! Two weeks later some horns fell in my lap here on TF when I read the Classifieds. I picked up Twistedtree's cast off Kahlenberg K-380s when he upgraded his N60 right after commissioning. The dual horns came complete with the tank, 12V compressor, solenoid and all the plumbing.
They have proven to be a welcome and popular addition to the boat. Even one of the Coasties docked behind me gave them a cheer when I briefly tested them in my slip after installation. Connected to my Fogmate foghorn timer, they provide great signalling in the pea soup we often get here in the SF Bay/CA Delta. Good horns can be entertaining, but they're also important safety equipment. It's a win-win!!
Here's what they look and sound like...
