In the vid the collision looked like the windsurfers fault. The kiter had launched off the wave first. Since the poley was down wind he should have held back a bit to give the kiter room instead the poley rode up the kiters ass and hit the wave after the kiter causing the collision.
Although at the start it was a grub move from the kiter where he was riding while the poley was riding the wave.
In the vid they knew each other and were try to film stuff. Matt is like that he does not care what craft you are on, just be good and go hard at it.
