RE: Deboichet stiffnes index
What you mean when say "unstable wind condition" ?
16-22 is a huge range so "unstable" should be bigger.Am I right?
Plus,doesn't the r17 come straight away from r13 profil (being larger on the tip)?
Another question is:
how a r13m+5 moved forward in the base (making bigger the distance of the chord from the end of the board) will behave in 161?
It's one of my old fin....
