I think over the years I bought ~ 10-12 new sails for Nacra 6.0's or 5.8. The quality control from EP has been dreadfull. When I got my last nacra 6.0 new in 2002 the mainsail had a stupidly long luff. the first time I put it up the mast, I thought they have given me a short mast. I had to cut 5" off the bottom of the sail to downhaul it.
Of the 6.0 sails I have owned, from vintage 1994 to vintage 2002 the measurements varied by up to 10 inches on luff lenght and 2.5" on width. Jibs varied a couple of inches on foot and luff measurements.

Good thing they are one design! I would not mind it so much if they did not charge premium dollars for them.

I have had new sails missing all the batten tie grommets, missing batten caps. Batten caps looking like they were peened on with a brick, some sails came with 1/4" rivets in the headboards, others had 1/8" rivets that needed reworking in less then 10 days of sailing.

On the other hand, I got 3 of 4 sails from EP that were awesome. If I had a bunch of money I would order 4 mains and 4 jibs a year, 3 months apart so they came from different batches and just resell the bad ones.

Contrast that to the quality of A class sails from Goodall, Ashbey, Ulman or DN sails by henry Bosset or 1D which are consistantly good and rarely have problems.
