Jon and I were both running the main line boof at Towers at about 700cfs.  I had run the boof the day before at the same level with a good line.  Jon and I had both probably ran that line at least 50 times for myself, probably, closer to a hundred for Jon.  I went first and had a good boof off the lip and came thru the initial drop fine but then flipped with a quick roll in the washout.  As I was rolling up I noticed Jon's paddle washing thru but I couldn't see Jon or his boat.  Jon vertically pinned in the main drop but about two to two and half feet to the river left of the boof spot.  Just to the the left of the seam.  The entire force of the pourover was pushing on his boat.  However, when we found his boat today it was completely intact.
