Same boat but under spinnaker, notice that instead of the Nacra C shaped boards, he's using more of a lazy L shape dagger, and T rudders, which I'm guessing have to be inserted from below, which would be a huge PITA when launching off the beach.



BUT...if they could come up with a simple way to insert the boards/rudders and if they build the entire boat of Carbon, it could be a game changer r.e. beach cat speeds. Nobody could afford one, but it would be a hellofa fast boat!
