Or you can get a Hydranet panelled sail or Spectra Membrane with far superior fibres for cruising for less than a 3DI polyester sail.I'm surprised lofts are still offering sewn Dacron sails at discounted prices when membrane sail technology has matured and at the moderate price points are only a small premium (20-30%). Agreed everybody got a bad taste concerning early membrane sails where the Mylar delaminated and the load bearing fiber was eaten by UV and flogging quite quickly. The skipper I raced with bought an orange (expensive) PBO genoa in the '80's that didn't last one season, ouch.
It's 2020 folks and North is marketing 3Di NORDAC (Dacron) sails using the same composite molding technology that the exotic AC racing sails use with ridiculously expensive carbon filaments. Sure it's double+ the cost of a sewn Dacron sail but may have 5 times the longevity long term concerning sail shape if cared for. Do the math folks. Or not; I've friends who are long term cruisers who point out they don't need the "racing" sail shape because they can accept losing a few tenths of knots under sail. Well, when *beating upwind* sail shape is a make or break issue, not a few tenths+- but is the actual ability to make progress to windward at a reasonable pace. Might matter on a lee shore. They point out the iron genoa is an option; one friend in particular has sailed south to Panama with shit sails and admits he was under power 75% of the time. Might as well own an RV.
My point is the North NORDAC 3Di option, although expensive, really isn't long term and should be under consideration for any blue water voyager who likes to sail.
