Foil Progress.

The flat foil rides well on takeoff and down the line but doesn't handle the intense power in the tube, there's too much lifting area that remains submerged.

 I'm making a split level foil so that as the foil speeds up, it automatically rises and reduces its lifting area so it can handle greater power.

 This is on a bodyboard because its a more stable platform for riding and I can see how the foil behaves.

 There's a GoPro on the front as well......   http://vimeo.com/57360827

 The plan is to refine the foil and then put it on a shortboard.
