Huh?
Hello,
That's a most unusual question. If the wire is somehow involved in furling, then it is unlikely to be a unit that you would want to use; there should be no torque on the wire for a conventional system, as there the foil rotates around the wire, and does not torque it. And even if this system somehow does involve torqueing the wire, 1x19 is not designed to support that kind of load. And even if it were, the core has the opposite lay, so it would unwind as the cover yarns got too darn tight. I really can't think of a good reason why the lay of the wire would matter here, even without considering that the sail could be wound up the other way.
This inevitably leads me to wonder what the sailmaker knows about rigging. Unless there's a factor that I'm missing -- and there may well be -- it sounds like you might want to do some independent research on the requirements of the furler. Start here if you like.
Fair leads,
Brion Toss
