Another victory for science following the lead of nature! Wouter I think you told me I was intellectually challenged for pushing this idea as I remember. Can't imagine you would have told the wright brothers that about the bird wing.
So tell me why your math and aerodynamic/hydrodynamic genius, experience and arrogance has not come up with this most basic understanding of "leading edge" (excuse the pun) sailing understanding....cause I know you know it all...just been keeping this under the bed?

: )

luv it when that happens.
