Sorry Mission Man I disagree almost in everything with you!!!
First this board has nothing to do with a cat design. Its a planning hull but with a heavy concave or more precise, inverted radius rails. It looks like a catamaran, but it is not.
I have to say that kiteboarding is much more like windsurfing (actually a special type of windsurfing) that a Americas Cup raceboat.
What you want of a kiteboard?
Please,define this and then look if this "new" design has what you want.
If it does, go and buy one, you will like it.
I am looking for easy planning , loosness, good turning, forgivness, control at high speed, good edging, lightness, and confortable ride. I dont belive this board is going to give me these things.
Perhaps, I am "traditionalist". I even see the Undergrounds trays playing with the corners of the traditional board design box. You could found that the last ones have rounded noses (traditional) but straight rocker (advanced). I think that in the future the oulines are going to be more curved again, not so straight.
A "boxy" outline make sense for a light wind board where planning surface is more important than forgivnness but a more flowing outline will always be better at high speeds. Extreme components in the design, works for extreme conditions (ej too light ot to high winds).
