They need to add a mast mount to make it a perfect all round water recreational toy.
I have this thought in the back of my mind of a kite assisted downwind board. Add a small single line drogue kite that gives that little bit of extra speed and lift to a shorter board so you can ride more runners and do it in lighter conditions.
It would be pretty cool to have a board that was fast to paddle and surfed insane!
It will be interesting to see the video footage!
Kinda sounds like the good old days of wave/slalom windsurfing boards. I'm not convinced you can have a board that surfs well and is competitive in a race. might do both pretty good but not as well as a surf or race specific board.
