Another thing that really got my attention was the fact that the guy was walking off of the beach with his kite rolled up around his board and the entire package tucked up under his arm.
Dang... how cool would it be to just grab a quick 30 min after work. I can imagine the rig would stay in the car at all times.
I see this a lot at Hookipa on the North Shore of Maui. Folks will pull up on their way home from work and set up their kites on the beach. They can walk out on the hard reef and step onto the waves, and off they go. Only experienced riders here. The tradewinds are pretty strong, and these folks are able to steer the kite, keeping it straight up, with one hand, and carry the board with the other hand. Mostly surf riding boards here, I think. The air these people get is incredible.
I've also seen kite boarders ride Jaws at Peahi. They don't need a tow like the board surfers do. These waves exceed 50', and sometimes the kite can't keep up with the wave. And, yes, the foils have shown up on all the different types of boards. A few years ago, when I first saw foil boards mounted on the roofs of cars, I thought they were model airplanes strapped upside down on the cars.
