That's wild. It looks like it took the pilot a while to figure out what happened.

I saw this happen to a guy at Manresa during a kayak surf competition in maybe 2001.
He was in a carbon fiber surf kayak and went over the falls and the boat was just obliterated around him.
He walked back to the parking lot with the two halves and his legs all scratched up from the broken edges.
He just took his backup yak off his truck and went back out. It was wild.
