I can't say how glad I was to have an airhorn on my vessel this AM. Yes, of course it is a regulation to have some form of sounding device on your boat, but I'm sure many people do not.
It was so darn foggy, I couldn't believe it. And fog usually lifts in my experience. Not today, from 0800 til return to launch at 11:45, it was one dangerous place to be in a boat.
Keep an airhorn in your boat. Great to be able to give a little 'heads-up tap' to your oncoming vessels.
