You are fortunate.

These electrical horns use a set of electrical contacts or "points" that are attached to a diaphragm. Current flows through the contacts to a coil that pulls the diaphragm and at the same time breaks the electrical connection. The diaphragm retracts, contact is made again and the process repeats.

The problem is, if the points corrode, there is no electrical continuity and the process never starts.

I can fix my horns by taking them apart and cleaning the contacts but that only works for a while. It's hard to do without either falling off the boat or dropping small parts into the water.

I keep a small compressed air hand held horn within reach for emergencies or when I need to point a horn in a specific direction.

This is the most satisfying whistle I've had the pleasure of using:

Off topic, but that bridge in the background is incredibly like like the Tacoma Narrows Bridge. Same design elements and it looks like exactly the same color.

OMG! The Queen Mary! I've got some picture somewhere of me riding the drive shaft of the QM. It was an alcohol related event after touring the ship's 7 bars. It makes quite a story. I'll try to find it.

That's the Ambassador Bridge spanning from Detroit to Windsor, Ontario. Not sure if it's related to the Tacoma Narrows, but I haven't seen it doing the wave, so that's good.

Keep in mind that they use a ton of air volume, much more than the horns, so you will need a good sized tank. If we were building the boat today, I'm not sure I would have spent the money on it, but we do enjoy having it. Every time we pass friends on the water they shout over asking for us to blow the whistle. One way to keep costs down would be to get the whistle from Kahlenberg and order a compressor/tank from somewhere else.
Harbor tugs usually had two distinct whistles. One was a "Pea whistle" for ship docking communications with the docking pilot and the Horn which was used for everything else...

Yes, they had both the whistle and horn. Horn used as horns are used, such as long blast when leaving the dock. Whistle was only used to communicate with the pilot.

lucky for you it wasn't underway...

Now, you get a tour of the boat, no engineering areas are allowed.

The interesting fact of the QM horns is that they now adorn the QM2 and are just as deafening. In our recent crossing, we had fog for 5 out of 8 days and heard them regularly while on deck. Your chest resonates with their sound when they blow the horns.

One of the original horns is aboard QM2. The other two stayed aboard QM. I think they sound at 55hz, which is too low to be legal these days. You do feel it in the chest, and it's magnificent.

The engineering areas including the bridge and the engine room were off limits to us, too. We sweet talked the housekeeping staff to get in, then disappeared into the belly of the beast for a couple hours. It was an incredible experience.

It was my last stay on the ship several years ago. I found one bronze wood screw in the recesses that has made its way onto FlyWright.
