Great thread! I am ready for a new mainsail for my Lancer 36' and am in the process of gathering info to make a final decision this fall. My local North Sails outfit has quoted me for a new, fully battened mainsail, but I've also priced one rather competetively through our hosts and their affilliate, Doyle. I've also requested a quote through National Sail Supply as per Maine Sail's recommendation above.
That said, my Local North Sails outlet has been very responsive and reasonable with the sail repairs they've done for me, so they are earning some loyalty points. On the other hand, as a business operator who needs to watch the bottom line, it makes sense to get some competitive quotes.
I certainly realize it's difficult to get an apples to apples comparison on this sort of thing, as the quality of materials may vary from supplier to supplier even if the sails were to be cut and assembled on the same factory floor. Does anyone who's recently purchased sails from multiple vendors have any input on this subject? In terms of use, this sail will be getting lots of it, in a cruising context. I teach predominantly in under 20 kts of wind, but regularly sail in a fair bit more than that - in sometimes fairly lumpy conditions in the Georgia Strait of BC, Canada.
Well-informed thoughts would be appreciated!
