Thanks so much for the info.
I would like to thank you for an excellent design service and can we get it into production asap.
My rough calculations give a 2% increase in speed for a 1% [IRC] rating increase so it appears to be going in the right direction and will improve our lighter air performance. I measured the backstay offset at the black band today and it was 250mm so I hope this is around the same as shown in the design.
Once again many thanks for your efforts
We must make allowances in the design for expected resultant twist and stretch etc due to loaded sail deformation as the Aero module assumes that the shape is a finitely solid structure which of course it isn’t. So it’s only a good indicator rather than a final solution.
The overall force increase between the two mainsails is 9.5 daN (dekanewtons)
