Thanks but these seem hoplessly optimistic for my TR, WK C36 with newish <4 y.o. dacron sails. I can only comment on the upwind to beam reach figures, since I believe these polars assume a spinniker once past a beam reach and my boat is not set up with spin gear.

Also, Since the wind angle is given as true, I'm assuming the wind speeds are also supposed to be true. Any idea if that's a valid assumption?
