OK, but I still don't understand what physics stand behind formula design so that it can sail downwind so well.
I think I understand why it excels upwind (long fin and the size that allows it to hold large sails and prevents the enormous force from the fin to roll the board over).
But why is it also so good in downwind course (comparing to a regular freeride board)? Fin almost not used here, so what else, wide, floaty stern that is easier to stand on?
P.S. Maybe these questions are weird, but I never tried the deep downwind sailing thus I don't know what it's like, the only think I know is that when it really blows I want to go upwind us much as I can just to slow things down
