I bought a new main for an Ericson 23 mk1 and a CDI furler/135% headsail package for my E27 from The Sail Warehouse. Both are fine especially for the money. I have purchased sails from Santa Cruz Sails in Santa Cruz (imagine that) and the difference in quality is apparent. That said, I would recommend Sail Warehouse for budget sails.
I have bought several sails from Sail Warehouse for customers wanting a good product and excellent value. Main, staysail and jib for Endurance 35, 135 jib and CDI roller for a Cal 29, Main for a Dana 24. I feel they are honest to deal with, know their products and deliver when they say.
In know this is an old thread but I thought I might put in my two cents for any one considering The Sail Warehouse. I purchased a E-32 in '06 and picked up a furling 135 and full battened mail since the existing sails were shot. I was very surprised by the fit and shape of the sails as well as the quality of build. In my early twenties I worked at a loft for a few years as well as have raced on many boats and have seen many different sails. For cruising these sails are as good as anything out there for two thirds the cost. The detail work is great. I would recommend them to my friends, and have. There you go. I think I may have run a couple of cents over.......
I just received a main sail for an E23 Mk.2 #359 from them. It was a Rolly Tasker. Price was comparable to other quotes. And they were very cooperative on shipping, as I found the delivery date would be while I was in Illinois.
