Kenduskeag Stream Canoe Race - How did these guys stay (relatively) dry?

I couldn't believe these guys (Kyle McGeechan and Cameron Wentworth) held on and managed to keep from taking a swim at Six Mile Falls.

The sequence will speak for itself.  The last shot is from near the bridge taken 19 seconds after the last shot by the rapids.  One can't see in too well, but it's pretty evident they didn't take on much water.  I've got the photo evidence, but I still don't know how they kept their boat above water!

Bravo!
