I couldn't believe starboard isonic pressureline of the bottom of the board and wrote this on the blog:

But I got some respond on the starboard forum from a student in Maritime Engineering. And starboard has copied the right graph! It is TRUE

I was thinking the way Antoine Albeau rides his board, and that is with the tail 99.9% out of the water. Fast for sure, but most windsurfers ride with less taillift, so the tail of the board is still a bit in the water, this fact produce lift, and the biggest pressure would be just in front of the front-footstraps.

Still what would be the fastest:

tail 100% out of water??? fin taking 100% of the pressure??? like albeau???

Or some other configuration??

Compared to albeau I don't see much (pro-)windsurfers ride this high on the water.
