Last September, coming down the California coast, I ran into a lot of fog in the mornings. I went through many cans of co2 air horns, making two-minute, periodic signals to warn off tankers, etc.. I nearly froze my fingers off, and two volunteer crew jumped ship because we ran out of air horns out of LA. Once I had arrived in San Diego, a delivery captain friend suggested that, since I owned a digital sound studio, I should put the fog sound signals on a CD.That way, I could put the CD player on single track repeat and just blast the sound signals on my cockpit speakers. This made a lot of sense to me, so I recorded the official sound signals, all 20 of them, and put all the right intervals of silence on as well, so when I loop the track, it repeats the signal endlessly. It works just fine. I have put these sound tracks on my music website, rdjansen.com and they are availble there free to anyone who wants to download them and burn their own fog signals CD. I would get radar if you are going to do much sailing in the fog. But it never hurts to be prepared in case you run out of co2.
