Due to the ocean racing
rules, I had to replace my coated lifelines
with uncoated wire. I first thought I might be able to just remove the plastic, so I used a knife to skin the cover off some of the old ones. It went pretty quickly and with a little care you won't damage the underlying wire.
In my case, the wire under the cover was corroded and many of the strands were weak. The wire was unsafe. I ended up replacing everything with 1x19 stainless and it has held up well for six years now, with no signs of deterioration. I strongly recommend that you throw away your coated lifelines
, and replace them with bare wire or hi-tech line.
