Rick, "Sails interact the same way."
Yes and that is one of the reasons why they have more drag.
Increasing a wings camber increases its lift, that is what an aileron (a second wing) does. That is why a biplanes wings are staggered and yes that is what the sails on a sloop are doing.
I fail to see how this is relevant to your claim that a wing won't produce a lift coefficient of 1.
Look at the generic 0012 foil here NACA0012H for VAWT from Sandia report SAND80-2114 (naca0012h-sa)
It clearly shows that at a zero angle of attack the lift is 0 and at a 15˚ AOA the Coefficient of Lift is around 1.5. I used 1 for the coefficient of lift simply as a typical number. . .
