If you are rec sailing, why would you care about going max upwind? If I was to spend a buch of money on something, I would want to make it as versitile as possible, which means class legal so I could use it to race, if and when I did. The current spin set up on the F16s allows for a pretty high aspect sail. This will go to weather relatively high compared to a lot of other designs, especially in lightish air. A close reach with the spin is a great ride.
