Funny, we are right on the water...some lobster boats commute to work each morning. The other morning, two of them set up shop a few hundred yards off the shore of our cottage at 0530 and I heard them. I couldn't hear exactly what they were saying, but the tone was clear enough. (They seemed to be setting a net to catch some bait fish for their traps)
Sound (especially voices) seem to travel quite clearly over the water when it is quiet!
The was one guy talking to the other two (actually doing all the talking) trying to teach them it appeared, and it sounded (with a Maine accent) kind of like this: "You take this line, and do this...no...no, not like that, like this...Jesus Christ, get your head out of your ass, like this...no...for God's sake, are you sitting on your brains?"
Heh, it went on for several hours and when I went out my wife (who had been up since about 0400 painting her paintings) shook her head in silence and asked if I could hear them...it was pretty funny. She had been listening to them the whole time while me, still in bed, drifted in and out...:)
I could live up here.
