Yes, Bill sail shape is entirely possible, although I think Busca's sails are newer.  I guess that is why I attributed it to the difference in settings (and of course John's skills!)
 
Before too much longer I need to get a new suit for Busca.  I'm looking forward to the improved performance.  The 155 is so blown out now it looks like a bedsheet!

Hi Tod,
The speed difference could also be attributed to sail shape.  It would have been interesting if you swapped sails with the other Mont to see if that made a difference.

Case in point...I had 2 identical (same cut, fabric, and sailmaker for the same boat) North brand mainsails on a 30' sloop and the only difference was age.  One 10 yrs old and the spare was brand new.  The difference in sailing performance was unbelievable.  The 10 yr old one still looked basically new.  The new sail outperformed the old in a big way, especially when beating.
