Rich and all,
Thanks for the suggestions. The only real problem is that 'Ram's on-line sound examples just don't want to work on my computer so I can't hear them. Thought there might have been other places to hear them, and that's why I asked. Probably wouldn't hurt to make myself clear at times, just too 'close' to the problem I guess.
Installation and hearing the thing shouldn't be a problem. The boat is certainly large enough, a 6" speaker would be no problem and an larger 'oval' speaker shouldn't either. There's ample power available. And if it's really needed, a small amplifier would also not be a 'biggie'. (The 'Rat Shack' makes a communications amplified speaker (4inch) that would be just the thing. Just not sure it would be needed or if I wanna 'rob' it from where it is - lol. Don't expect great fidelity, loud and fidelity don't really go together.)
The second problem is that I've never heard a real live tug boat horn. Sure, in movies etc, but just not many boats of that size around Oklahoma, you know? But as long as it sounds sort of 'real', and 'right', who cares, right?
Thanks again...
