Has anyone done this? It seems like the PVC just contributes to life line
degradation. If so, what was your source for the wire/fittings? -- "j" ganz @@ www.sailnow.com |

I think I will replace mine with plain wire. The Genoa and I rub
against and grab the plain wire shrouds all the time without any sign of a problem. I took the split PVC covers off the shrouds and was amazed at the gunk underneath. Can't be good for a metal that needs a replenishing supply of oxygen to avoid corrosion. I've heard or seen something somewhere about using some of the new super low stretch rope for lifelines. Has anyone heard about that idea? -- Roger Long "Capt. JG" wrote in message ... Has anyone done this? It seems like the PVC just contributes to life line degradation.

I have been looking before to replace my life lines. In Canada, I found at
Canadian Tires, 9 strands Stainless wire labelled aircraft quality. On the same rack was the same wire with vinyl covering marked $1.49 per foot. I was ready to buy but I did not have the tools for splicing the (Pelican) end connectors that hooks on the bow and stern pulpits. I have seen some sailors using SS U-bolts to secure the connections to the pulpits and stanchions. Not nautically elegant but safe. Conversely West Marine are showing (Internet) as showing 304 Stainless Steel 1 X 19 Rigging Wire from $0.79 USD. "Capt. JG" wrote in message ... "Bob" wrote in message ups.com... Capt.

I have seen many different parts of a boats rigging being replaced with new high modulus ropes. The multihull world is embracing rope because of the weight savings. They are certainly strong enough and look good but the are a couple issues that warrant thought. First of all is the UV degredation. It is much greater in any rope than in wire and requires more frequent replacement. The second thing is nicks. Wire will stand some abuse but a nicked rope will be much weaker. I have seen a couple boat lose their rigs because of nicks in rope backstays. Finally the splices in the new ropes are much more challenging and many require special splices to ensure the strength isn't lost. It is doable but think about pros and cons first. Gary |

7x7 uncoated is hard to come by but 1x19 is fairly common. A good bit
stiffer but that shouldn't make much difference for lifelines. I have 100' of 1/4" Amsteel Blue which I am considering using. Stronger, easier to fabricate and a lot cheaper installed. If I can just get past having blue lifelines. :-) -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

I've started a new thread about this because I think you bring up an
interesting topic [called "Rope as replacement for lifelines" and it is just divergent enough to warrant that. I'd very much appreciate anyone else's opinion or insight about this topic, and especially any experience anyone has with it.

It weighed practically nothing and had epoxied/screw-in connections; no bulky swages or clamps. The pvc failed and cracked after 20 years and I could never find a continuous, unsplit run to cover it with again so I got the s.s. stuff. Much heavier- less cool. One other option if you could find it. (perhaps the UK). Sounds like 'Parafil'. Very light, very low stretch, easy to DIY at appropriate lengths. See http://www.linearcomposites.co.uk/prod_parafil.htm I used it for several years while racing (hmm, err, in 1973 to 1979!) and once, while clipped to it, went for an inadvertent swim for about 5 minutes at 7kts. Since then they've developed several different versions using different cores. On my last boat the upper lines were plastic coated 9 strand stainless, lower lines plain 9 strand stainless, both with swaged eyes at each end. After 16 years the plastic was discolouring brown due to UV deterioration on the upper side of the plastic. One section (of four, I had a centre gate) had some rust stain showing at a single location on a kink. I stripped the coating to see what was going on and found a crack in one strand. The rest of the wire was clean. My assumption is that the plastic coating was sufficiently porous to oxygen to permit chrome oxide coatings to exist on the wire, though why that didn't apply where the crack was was not clear. Replacing the wire was a bore, since the line threaded through the stanchions, and the swages prevented removal! Bad maintenace design. So I had to trot down to the rigger's shop with a whole lot of stanchions etc in my arms. -- JimB http://www.jimbaerselman.f2s.com/ Describing some Greek and Spanish cruising areas |
