You get what you pay for
While I'm sure that there are some great deals to be had from small sail lofts, I firmly believe that it's worth it to get sails from top-tier sailmakers if you can find a good deal. Doyle, UK, North, Ullman, etc. North Sails just had a promotion where you trade in your old sail (it could really be ANY old sail, torn/abused/dirty is OK) and get 25% off the cost of a new sail at full price, which worked out to a little better than what I had been able to negotiate in quotes before. So I got a new main with two sets of reef points and a 105% jib, both of 6.5 oz premium "racing dacron" with battens, draft stripes, telltales, numbers, the works, for just over $1200 out the door. And let me tell you, what a difference! When I bought my boat, the previous owner had just purchased new sails (from some place called Gaastra Sails) for about $800 two years prior, and the latter of those two years, the boat was just sitting in storage. So I was expecting to have some pretty good sails. They were alright at best. I think I could have done about as well using bed sheets. The main never took on a good shape, even though I have most of the sail trimming goodies on my boat. It was always too baggy, and the draft was always in the latter half or middle of the sail, never in the front where it needs to be. When I put up my new sails from North, the difference was like night and day. Even when I had a double reef in the main, it still held perfect shape. Draft in the forward 1/3, long straight run aft (even without battens), no cupping at the leech, and I was able to get it as flat as I needed it. My point is that there's more to sails than price, and getting sails from someone who knows what they're doing makes a big difference. There are probably very compatent lofts out there that are cheaper, but if you go top-tier, and shop around, you can be sure to get the best sail for your money.
