Who uses a fog horn in the fog?
Another thread about radar use had me thinking about low vis ops. I run a Fog-mate fog horn in low vis but I usually only hear fog signals from commercial vessels. There are often MANY recreational angler boats in the vicinity but I never recall hearing one from them.
Do you have an automated fog horn signaling device on your boat? If so, do you use it regularly in low visibility conditions? Is it a radio function over a loud speaker on the bow or does it involve the use of your vessel's horn system?
If not, do you just estimate the timing and sound your horn about every 2 minutes?
Do you notice many other boats in the fog using their fog horns?
Sometimes I wonder, "Is it just me?"

Just added PA/Fog speaker to my S/H GX2200 this past winter but no fog around. But I do now use my “anchor “ ball. Keep forgetting to take it down when leaving though!!! Nobody and I mean nobody cares.

It's rarely I've boated in fog where visibility was less than the range of my horns although my air-powered horns have twice the required range (requiring four times the volume) for the boat's size. And yes, do use it when visibility is obscured, and do have a device that gives the required signals when turned on.
And yes, don't recall other boaters sounding. Believe it is worse with sailboats (and "lesser" vessels) since they are usually limited to lung power or low-capacity, hand-held horns, or none at all.

Your attorney should care.
But then, that's a different topic.

I use my automated fog horn as required...with the exception of narrow ICW residential stretches where it would be more annoyance than real help.

Yes. I have one of the automated hailer/fog signal devices which I have used several times over the course of this summer, in visibilities as low as 1/8 mile. Never heard anyone else, but I'm not sure if that's a function of the other guy's horn/no horn or my own engine noise.
I do reduce speed during low vis ops, more to mprove my hearing than to reduce collision damage.
My device actually has an output volume control. Damm if I know why.

You are depriving the residences of the maritime experience. They paid for it: give it to them.

I always use our automated fog horn when the fog is thick.

Opening the pilothouse doors and even sticking one's head out helps

I use an automated fog horn which is built into my Icom VHF radio, whenever conditions require it. I've been known to use a fair amount of volume. Kind of fun to watch on radar, the radarless center consoles fishing in the inlet, scatter when they here me coming.

We brought a previous boat down the west coast from Seattle to LA and were underway one time for 30 hours in very thick fog. Used the automated system the whole time. The horn got really old during that time period. We have a hailer on the current boat with front and rear facing horns hooked to the hailer so we can make the required signals.

Or is it just us wanting to sound off our Kahlenberg air horns?

I use the automated sounder in the VHF. Then if in close proximity to other boats, I hit the big horn button while the VHF is sounding.

I have a Fogmate connected to my Kahlenberg D2's. I love to turn them on in the fog. They sound a bit like those on a ferry or something else very large and I can see smaller boats on my radar scurrying out of my way!

I like the way you guys think. I'd rather scare them away than hit them accidentally.

Same here on the D2, particularly when it echoes off the hills and tall buildings. Also when entering and leaving the marina when the breakwater restricts visibility at other than high tide. Initial response from nearby liveaboards: "what the hell was that!")

Yup. Do that too. Still haven't heard another yacht or fisherman. Tugboats yes.

I did it once. Listening to that darned horn was the worst 10 seconds of my life. Just kidding. If I'm out in a very heavy fog I drop speed down to about 4-5kts and watch the radar like a hawk.

Very seldom out in heavy fog but do use it at those times. Have rarely observed other pleasure boats doing so. A couple of power boats, never a sailboat. Many commercial vessels doing so.

I use a horn from a ship, loud, so everyone but ships get out of the way. I have a random timer so it's not exactly 2 minutes (in case someone approaching is exactly on 2 minutes).
