The guy who I bought my NACRA 5.7 from had been using a NACRA 18 squared mainsail on the boat. I like the characteristics of the sail, but it's too tall for my boat so I'd like to replace it. Unfortunately, I've been having a heck of a time finding anywhere to buy a 5.7 mainsail, and none of the sailmakers I've contacted so far have a pattern for it.
Any suggestions?
