Mast pa horn speaker

Some VHF sets such as Standard Horizon 2200 can output to a speaker for both microphone and automatic fog signals. Check if yours has this capability.

Horn loaded implies pa which implies tannoy which would be 100V line

I suspect it actually means nothing more than that the speaker is shaped like this: :)

This is the one supplied by Standard Horizon for use with their radios; it's 20 watt, 4 ohm apparently. I imagine others would be similar and other radios in hailer mode would work with this one.

Very much doubt that anyone has large 100v PA amplifiers on a normal yacht!

Aha!, fair dos. Just for info, the 100V standard does not necessarily mean big. it means high impedance speakers that can use long, thin cabling.

Yes, mine is like that but input 30w ,8 ohm.
 
At last. I now have a 2x 20w amplifier with a mic input. Question is, seeing as it has two speaker outputs, what do i connect to just one mast speaker?

If you only have one speaker, just connect it to one output - leaving the other unconnected. Don't be tempted to connect them in parallel, or anything else clever, as that will almost certainly damage the amplifier.

I must say, that if you bought an amplifier with stereo output (and, presumably input), it's not really what you need. There are plenty of small PA amplifiers designed for 12V operation that allow microphone input and low impedance speaker, usually with at least one "music" input also - one of these would probably have been better. (sorry didn't see thread earlier!)
