I have had my McNamara sails for 4 years and used them a lot in testing winds. They are still good and do not apear to have stretched. They still set well and are very controlable with the cunningham and outhaul. They are at the higher end of the price range but when I ordered my sails I was asked about the type of sailing I do, My crew and helm weight, where I wanted reefing points, what life I expected out of them. All this is in with the price. Mike then made a bespoke set of sails for me. A case of you get what you pay for.
