Questions to the OP, you said 3 lofts quoted you similar prices. Inquiring minds want to know, who else out there is selling sails that cheap?
Taskers and Lee Sails quoted the same or less, delivered
Jack/Jude, alarm bells are ringing here!
Taskers sails are made in SE Asia somewhere (I but don't remember exactly where) and it's probable that Lee Sails are also, although they didn't used to be many moons ago. Please don't wander into the same pothole again.
The biggest issue with these sails (speaking from experience with Taskers) is not the quality of the cloth - that's generally fine - it's the single (or missing!) stitching and generally crappy workmanship. If you know what you want (eg. a light-air spinnaker) it's generally no issue.. you just need eyes wide open when dealing with these guys because, yes, you do get what you pay for.
You'll be paying more to have the right thing done, but if you're even thinking of going anywhere else I'd suggest you contact either Doyle Sails
or Steve Walker Sails
, both "real" sailmakers and both in Hobart. If you're stuck with the sail you have, take it in to one of them and ask them to fix it.
