He's unreal...

That looks like pretty advanced windsurfing technique to me...
Basic moves, but expertly executed.

one handed duck jibe is the shiz!

Yeah we know he's good and can do most maneuvers , but can he do a no-hander gybe? (Didn't see one here).

Most probably!

PS: Met him in the early 90's and got his autograph when he came out to our local sailboard shop "Bai Snow n Sail" in Five Dock. Nice guy.
