The VHF radio that I installed last year has provision for a loud hailer/fog horn. All you need to do is wire up a horn speaker and you're good to go. It has built-in automatic fog horn signals that you can use. If you yell at someone, it has listen-back capability (speaker becomes a mic).

All of this sounds like neat, useless stuff that I'd never use. But I have a chance to get an almost-new speaker for $10 that I could mount under one of my transom seats, so I'm debating getting it. My wires come out a clamshell vent right under the transom seat, so wiring it would be a piece of cake.

Have any of you found a use for a loud hailer or fog horn? Do you wish you had one?

My VHF (Uniden 525) came with the same setup. I purchased a horn to go with it, but just couldn't find a spot on the boat where it seemed to be out of the way. I'd never really thought about hanging it under a catbird seat, but that's not a bad idea. I'd have to run wire to get there though. For some reason it just seemed like it should be in the forward part of the boat to me. I'd always thought about hanging the horn down near the rub rail on one side or the other, about three feet or so forward of the mast. However, all I could think about was Mad Max when I envisioned the placement. Anywhere else on the coach roof and it becomes a trip hazard. I'll be curious to see how this thread plays out.

I've never been caught out in the fog yet on this boat, but having it rigged would be a good idea I think.

The horn speaker under the catbird seats? You might want a little hearing protectoin for the folks in the cockpit.

Yes, the cockpit would be very noisy with that speaker under the catbird seat. But as David said, there really is no other out-of-the-way place for it. Since this is something for emergency use only, I could endure a little discomfort. I could also point the speaker to the side or stern, or better yet, install it in a way that allows it to pivot. It seems an ideal place for it because it's out of the way, and I already have the clamshell opening for passing the alternator cable, RAM mic cable, and 12v connector wire. One more wire 2-conductor wire would fit.

As a practical matter, there is a potential problem with feedback if it's under the catbird seat. Since I have a RAM mic mounted right there, if I used that mic for hailing, I'd likely get feedback. But on the rare case that I use it, I could grab the mic inside the companionway instead.

Maybe on a spreader?

How about mounting it just below the spreaders on the side of the mast facing down? Should be out of the way most of the time.
