Joe. I'll echo that advice about telling the sailmaker which way the sail rolls on the furler! We bought new sails for our CAL 21 in 1993 from Thurston Sails in Bristol, RI. My Mom and I finally convinced my dad to add a RF for the jib at that time, and so he bought a CDI furler from Thurston at the same time that he ordered the sails. When we rigged the furler and bent the sail on.......we suddenly realized that the suncover was on the wrong side of the sail! We always had to spool the line on the furler drum in the reverse direction from what the instructions said in order to compensate for that. A lot easier than having Thurston fix the sail! You would think that if you bought a furler and the sail from the same source that the cover would be on the correct side, but it wasn't. Thurston used to be one of the top sailmakers in New England (and beyond!), but during the 1990's their quality and customer service slipped.
