Necklace
I got the beads at a local arts and crafts store. I think I used about 20 of them. The ones I found only had holes that went about halfway through. I through-drilled them myself. I dipped them in epoxy to seal them from the elements and to make sure they didn't splinter, etc. I then strung them on about four feet of 1/8" Vectran line (New England Ropes V-12). It's very strong, doesn't stretch, it's pretty slippery so the beads roll easily, yet it holds knots very well. Center them on the line by tying stopper knots in the line, one on each side of the beads. Make sure the beads are not too tight between the knots or the necklace won't bend around the furled jib. Then tie both ends to a snap shackle.You might need to adjust the length of the necklace to suit your own bow setup -- it kinda depends on the orientation of the tack line block, your furler drum, the bow pulpit and any anchor rollers you have. The goal is to avoid chafing and to make sure that nothing hangs up when you jibe.Also, you may not need to use that many beads. We have a new genoa and it doesn't furl very tightly yet, so it's kind of fat.I'm also thinking about using more than one necklace to help spread the load on the furled sail. The ATN "Tacker" product (which this necklace thingy replaces) is quite wide and does a better job of spreading the load. The beads move up and down better than the Tacker, though, and are a hell of a lot cheaper!
