T&T: Air horns

[bob Austin]

If you want loud, with some better quality than the "cheapies" but not the
price of the high end horns, Google Seige-Engineering.  They have a wide
assortment of "locomotive horns"--which are brass, chrome plated (gold if you
wish), with good sized 12 volt compressors and good size air tanks--the sound
output is up to over 150 DB--that will really get attention!

My feeling on a real cruising boat, you want a real horn which will be heard
on a ship's bridge a mile away--and there are few if any electric horns which
will do this.  (I understand that there are some "fire engine" electronic
horns which are also very loud)
