Hey, is that an XFLR5 run I see there? Thank you for sharing what most sailmakers would lock down at the bottom of their treasure chest.

I can see that the sail have a bit better L/D ratio in theory. Was the theorethical L/D delta between the sails proportionally the same over the windspeed range? You dont think using XFLR5s 2.5D algorithm can be a problem for the results.
Interesting that you choose to use 0deg twist <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
