Compare apples to apples
I did an in-depth survey of sail makers and costs last year for a new headsail. I found that for CD, you get about the same value as you could get anywhere else for a stripped-down sail of the same specification. When you add the extras, such as luff foam, reef reinfircecments, blue-water finish, etc., they cost more. I imagine this would apply to soinnakers too.I would obtain quotes from all around, and I prefer somewhat local, good lofts. When quoting, make sure the specification is the same. One problem I had with North is that they would never quote exactly what I wanted, every quote deviated in some way. jvp.s. I bought the headsail from UK in Jamestown, Rhode Island
