Thanks Dude...

...she's a beauty.

I'd agree with everything you say except relative to going "against the wind"

Sail shape does play an important role......
...but its more a funtion of Laminar Flow and Hydrodynamic lift from the keel.

Hence multi hulls are renowed for crappy upwind performance...
You can shape their sail any which way you choose, but because
they have no keel...they slide sideways and dont have the lift/flow
of the keel to "act' like a wing and turn side force into fwd motion.

I have never thought of that, that makes total sense.
