The sailmaker of a friend of mine designed his asymmetric with a luff 2,5% longer than the max halyard to end of pole dimension.
This, in his words, to accommodate the longer luff measure due to the luff curve profile when sailing.
May you tell me if yr sailmakers do the same?
In the affirmative which is the chosen percentage?
To answer you need to have a look at yr measurement certificate to get the luff dimension of yr spi and to measure the distance between the end of pole and the max spi halyard point on the mast


Another question:
does yr sailmaker stick to the 75% plus midgirth rule?
In other words the SMG (half width) of yr asymmetric is close to the 75% of SF (foot) or is close to 80% (the mandatory rate in the Tornado class rule)?
