Hi Alan
Yes ,-based mainly on I-20 specs which is fractionally under 208 sq ft inc. mast area , though may fine tune to 210 to give some room to existing boats to change , with the 32 mast length the luff dim. and aspect ratios should remain basically the same .-Worry a little about sail stretch with spin particularly in measuring sq ft over time .Would not want to have someone with an older sail inadvertantly measure over due to material stretch.
Tryed to keep them as simple and inclusive as possible,
Is there interest on the west coast Alan ? -
