I don't believe windsurfer is similar to kiteboarding (and I could be wrong here, I don't windsurf) in respect of the edge of the board being used. Most of the high wind footage I have seen is fin orientated riding. The reason I compared it to yachting is the fact that you often see cats travelling on only one of the two hulls.
In many respects, kiteboard is very different, because unlike windsurfering, you have no fixed mast point, and unlike yachting you have no fixed mast full stop, and unlike wakeboarding, you have nonbody driving the boat, so this is something completely different. As mentioned before, the only real answer to this are trial and error, and with that we will have some radical designs.
Don't get me wrong in respect of this design. I have no idea of whether it will work, and only testing will figure that out. All I am saying is that the purest ideas will need to be thrown out the window for new ideas to come to light and "possibly" advance this sport. I don't support this design until it has been tried and tested and proves it works, but I don't like the idea of throwing it aside because it goes against the grain of what we know. I do support someone who has the balls to throw all the current ideas out the window and start from scratch, because thats where history is made. I will test the design, and I will be able to shed light on it, but again, it may suit my style and not yours (if you call what I have a style
