Plastic shroud covers OK or not?

[Brion Toss]

Hello,
I'm with Ian on the turnbuckles (and any welding supply shop will have TIG rod, probably in both stainless and bronze), but I have seen numerous wire failures from tight-fitting covers. The problem is by far the most serious in warmer climes. My favorite story was about an owner who religiously checked his terminals and the bottom of the wire, by sliding the shroud covers up a few inches, then sliding them back down. The wire broke near the top of one cover, and the rig went over.
Loose-fitting rollers can be disorienting to grab onto, but I actually prefer them, as they make it easy to swing past the shroud. They also can roll as the sail passes, and present a much larger radius to the sail, reducing chafe that much better.
Fair leads,
Brion Toss
