I loved that vid when Blane first posted it on the Zone about a year or so ago.. He just stuck his GoPro just ahead of the fin on the bottom of his board.
Interesting now much air gets trapped flowing under the board.. Blane uses a slight single concave in the nose area and I'm sure that helps channel it through.
. Tripod the turtle was pretty curious.. You think he might have learnt his lesson by now
