Rolly Tasker / National Sail Supply, hand down. I am very, very picky as I am, and have been, an avid racer.
I highly recommend National Sail Supply in Florida!! I have now purchased eight or nine sails from Dirk with zero issues. They are beautiful sails, great shape and are very, very well built.
Dirk used to work for Rolly Tasker in Phuket and was his GM at the largest sail loft in the world. He decided to move back to Florida and open his own sail business selling and importing from Rolly, all his sails.
The sails are made of US woven Challenge sail cloth which is the the same cloth coming off the same machines as NorDac, North Sails Dacron.
How do I know this? My local sail maker got a batch of Challenge hi modulus and it was accidentally packaged in NorDac wrapping.. Doh.. oops...!
Another thing about Rolly Tasker sails is that they build cruising sails for LOTS and LOTS of the big name companies here in the states. I promised Dirk that I would not disclose who RT builds for, and I don't know them all either, so I won't, but you would be horrified if you knew even a few, especially at what they charge, trust me.
If you think your small loft is actually building your sail you may be wrong as Dirk & Tasker also supply many local small time guys who sub out the cruising sail business through Dirk/Tasker.
I ordered a new main last winter for my CS-36 and it is simply beautiful.
A good friend and I both ordered sails at the same time last winter, his local mine mail order. My sail is triple stitched, his is double, mine has a solid riveted head board his does not, my reef points are built to an off shore standard his are not, my tack & clew reinforcements are built for off shore use and his are clearly coastal, my batten pockets are more secure and better designed and adjustable, my clew and tack are both hand finished and stitched in UV resistant leather.
Both sails look to have been designed on the same computer system and both have excellent shape and are within +/- 2 feet of each other luff length wise. I am his main sail trimmer so I do know my mains. He should have ordered a RT sail...
My new sail with top two battens full, draft stripe, logo, 8.3 oz Challenge cloth, three reef points, shipping and a brand new sail cover was $1713.00 delivered. His was $3400.00 with 7.6 oz and no sail cover....
I would not bother going to other Tasker dealers as Dirk has the lock stock and barrel best price to feature spec/ratio of ANYONE. I checked them all and compared features and specs and price. Dirk has the inside scoop and as Rolly's ex general manager. I assume, because of this, he gets better pricing than just about any other Tasker dealer??
This is not a one time deal for me I have purchased CD-27 sails C-30 & C-36 sails and now CS-36 sails all have been spot on and the absolute best price I found anywhere.. For cruising sails they can't be beat!

P.S. I have a barn full of old North Sails, Hood, Doyle etc. and NONE of them were any better than any of the Tasker sails I've owned. If they were better I would not be on my 8th or 9th sail from Tasker..
