the new Nacra F20na fits nicely in the Open 20 rule set. I don't think that was their goal but it is nice how it does. do i think an updated N20 can compete with a F20na? who knows? that's why we actually have the races. it's not a foregone conclusion. if it is faster then you will see a gradually move towards the new platform and as time goes by the class develops. This is the future of our sport.
