This original of this video was posted on the World of Windsurf Facebook(and You Tube) page so I copied it and then slowed the gybe right down to have a good look.
Framerate wasn't that great so its not smoooooth slo mo but I have found it very helpful.
Shame you can't slow mo You Tube yet but it will come ..... Peter Volwater is in a Dutch GPSTC team
really interesting when you watch the board on freeze frame... absolutely no bounce - he has it carved so hard that there's no slap into the water at all
noice
with my gybes, i always feel like the mast is always perpendicular to the board. if i lean the sail down towards the apex of the turn, the board tilts harder and the turn becomes sharper. but during this gybe, you see the board is at a really acute angle to the board during the lay-down part, and the board more or less tracks on the same angle thru the turn..
i have to give that a go, trying to maintain a steady carve when i go to lay the sail down. it explains why i always stall when i go for a lay-down, as i end up tilting the board waaaay to much.
