I'm talking about manufacturing processes, not people. People aren't making sails anymore, not laminates anyway, and the dacron stuff is usually completed in other countries w/ much cheaper labor. They're just finishing them/selling them. Q sails (in my experience, laminate sails) hold their shape longer w/o delamination. They do tend to be a bit heavier than North. Norths are fast, but after 3 seasons, they're starting to fall apart.
The above does not include 3Di sails.
I won't disagree with you about the manufacturing processes, but you'll find, as has been the gist of this thread, that people are important too.
There are a myriad of factors (also laid out in this thread) that should be taken into account when making the right sail for any boat and it takes an experienced sailmaker to know what those factors are and to punch in the right numbers. As the saying goes: "garbage in, garbage out"...
Fortunately for you, Quantum will have the numbers for your boat on file for all time, as entered by an experienced sailmaker - but if you ever bought another boat and needed a sail made and the guy you are currently dealing with is working for someone else... good luck to you.
EDIT: The core issue here is that computer-cutting has made sailmakers world-wide... LAZY! They can now churn out very expensive high-speed racing sails for the same high-profile boats every season and make a small fortune out of it without ever having to so much as think
about what they're doing... but give them a brand-new, specialist, low-budget, non-racing, low-profile job to do and the vast majority (Quantum and Norths included) simply can't handle it.
