So my friend, the guy videoing and talking actually isn't even a boater, but he's a former ski patroller and dive master and has pretty good sense. He was riding along with the guy who was rowing his own raft, he was kind of a friend of a friend. The guy on the oars seemed a little rookieish to me too, but at least he didn't do the classic post-carnage flip while forgetting to keep his own boat upright. I'll ask him what kind of camera he was using, I thiiiink it was his regular digital still camera in video mode, but it did seem like a helmet cam.
Ideally, they would have tried to run their formation tighter, could have bagged a couple of swimmers, or whatever. My friend with the camera did end up getting to the other boat and no one was seriously injured it sounds like.
The guy in the front boat, Crazy Dave, has some grand trips, and lots of years of boating under his belt. I think a lot of his experience might be blue-side-down though
and there's a reason he is "Crazy Dave"!
