Going to redo lifelines in Dyneema...what size?

Going to redo my lifelines in Amsteel Blue...What size? 3/16" is what I plan on using. Also what to I do about the gates? My wire lifelines have adjusters for size? Should I go with something like that or just skip those and measure VERY carefully? I plan to splice it myself...any tricks?

Re: Going to redo lifelines in Dyneema...what size?

I used 3/8", not so much for the strength as for the ability to grab hold of it easily. It makes a good armrest when sitting as well, although you could probably cover thinner stuff. I used eye splices on all ends. They end with s.s. shackles at the gates and lashings (1/8" Amsteel) at bow and stern fastening points. The lashings work out really well to both tension and to take wraps around the entire bow rail assembly, not just the weaker welded-on round stock eye. I spliced my old-style pelican hooks right into the line to make the gates which swing on the shackles attached to the long bow-gate pcs. No turnbuckles, no swages and wire to corrode and worry about, easy to take off, roll up and stow....simple, love 'em.

Don't worry about splicing 12 strand. It's very easy. Sew it to lock in place as suggested in specs. Seriously think about lashing instead of screwing around with turnbuckles. With a long pc. of lashing, you can leave all the lines 3" or so short and tension to fit, using the shackle at the other end as the stop. The only thing that needs to be exact is the gate pc. which provides the actual tension via the pelican hook. They need to match your gate opening. Being short, the eye splices will overlap, making them essentially doubled up. When measuring make sure to add enough for splices.

The size has more to do with comfort then strength. if you slip and get caught by a 3/16" line it will take skin off a lot easier then a larger line. trying to hold on to 3/16" line will hurt and cut into your hand. Use the largest line that will fit the stanchions with the chafe sleeve on the line.

Hi Smurphny,
Sounds like a good job. Got any photos?

Re: Going to redo lifelines in Dyneema...what size?

Hi Nemier, Thanks. Sorry, I have no pictures. To add to the earlier post, I re-used the old eyes from the wire lifelines by just cutting off the thread end of the old wire to couple them to the pelican hooks. The only cost was the grey Amsteel and a couple of 5/16" s.s. shackles. Have had it on two seasons now and the line shows 0 sign of wear, sun degradation, or abrasion.
