Ever had your leg hair ripped out by wire? Or had stitches from meat hooks? I have had both, and trying to put in your own stitches 500 miles from shore is a bit uncomfortable.

I don't think wire is particularly difficult to install, so long as you have your own crimper, and somewhere to roll out the wire. I can splice a set of dyneema lifelines up then toss them in my sailing bag.
Nicopress sleeves cost a couple of bucks each, Wire is supoer cheap, I have had a lot given to me. My 1x19 SS has had zero meat hooks in 29 years of use.

Re: New England Ropes Synthetic lifelines?!?!

I'm still here. Yes you can use a thimble as your 'gate tension', just make sure that when you splice the line around the thimble you can still fit it through the stanchion. You'll probably still need to find a way to adjust for constructional stretch.

It'll be a little challenging. You may need to remove a stanchion near the gate to splice the line, then pull on the stanchion and reinstall.

Paul,
You might want to ask your question in a separate thread. Some people stop reading when the threads get too long.

Re: New England Ropes Synthetic lifelines?!?!

I need to replace my lifelines and am considering the WR2 system...any suggested resources showing the best way to implement them? In particular I am interested in the best way to manage the gate. My current wire system has the typical double rings, I assume to maintain tension when the gate is open...I wonder if this is even necessary; a long line with a thimble forward (for tensioning) and a pelican hook (with rope adaptor) at the other end would be simplest (and cheapest). Any suggestions or best practices would be appreciated!

TIA!

You can use it if you want. Johnson makes a very nice threaded eye that fits their standard gate hardware, they just want an arm and a leg for it. I probably wouldn't keep the turnbuckles, but the over center gate hooks are still commonly used.

Evans Starzinger just posted a first draft of his take on this subject over on CA...

As always from he and Beth, an excellent, informed analysis and recommendations...

Re: New England Ropes Synthetic lifelines?!?!

That's really the terrible truth about all swaged fittings--they cannot be visually inspected. There's no real way to know if water has penetrated, if corrosion has started, or for that fact, if the original crimp or installation has some sort of fault. These end terminals ALL give me the willies. My old furler has an integral Sta-Lok swageless base. I don't even like to think about it. Even all the new Suncor terminals I used when replacing the shrouds and stays don't give me the confidence that a sturdy, visible eye splice would. I would like to know what percentage of end terminals fail and for what reasons.

The best solution would probably be eye-spliced bare wire. Brion Toss has a good method of splicing 1 x 19 wire in his book and a demonstration online. Brent is right about wire being tougher. You aren't going to slit it with a sharp edge. That's my main worry about the Dyneema. Once I become proficient at doing wire splices, I may start replacing all my swaged fittings, swageless and swaged, with splices.

As far as length of Dyneema lifelines goes, I would leave 6" and use lashing. That's what I did and it has worked out well. The lashing method allows adjustment for stretch. Dyneema does stretch over time. My 6" is down to about 5" now, maybe a little less. Another plus for Dyneema is being able to easily wrap them up and stow them in a locker. I spliced around 5/16" shackles at the gate ends. The shackles act as stops so that the gates, when secured put tension on the run.
For what it's worth Brion Toss is on record saying he nor his shop will install wire lifelines anymore. They will only use dyneema. The reasoning he gives is that he considers wire dangerous, more expensive, and harder to inspect.
