I have recently aquired a new,to me , Endeavour 33. After going through all the extras that came with the boat, I found an assymetrical spinnaker, with sock. After much research I believe that I need something like the ATN tacker or the parrel beads that Niel Pride sells. Somewhere in my reading it was mentioned that golf balls could be drilled and threaded onto a stainless wire rope to make a home-made version. Has anyone tried this ? If so is it worth the effort, or should I spend the money?
