Just to add to their uniqueness , they appear to be fixed down with three fcs plugs . could the board be a five fin setup of plugs . and the side fins are like a Hydrofoil or tube cut to a thong or y shape looped over or around back to the other plug ?

Regardless , it reeks of Jetski assist . can almost see the wake in the back ground of one of the shots ?

They're called 3-D fins. Don't know much about them except they're used by a few guys in WA. Here's a short vid: www.vimeo.com/28101251

Would've thought they'd increase drag but I'm no hydro engineer...
