Kevlar Rope for Halyards or Even Stays?

[Captn_Black]

Is there and reason that this couldn't be used for halyards or even the 19mm version for stays? - Buy length of 10mm braided Kevlar ® rope here

Looks good to me, light weight, fire and abrasion resistant, doesn't rust, doesn't get 'meat-hooks', less wear on sails...

I'm searching for exact technical spec's now, but they say its stronger than steel, but i don't know if they mean relative to weight or thickness.

Um, it does not list % elongation, breaking strength, construction, or maker. Hard to give you an answer.

After looking further into it, maybe this would be better if I want non-steel stays - DSM Dyneema fiber. Extremerigging performance

Opinions?

Thats why I asked here hoping someone had some experience with it. I'm reasearching further now, but if anyone has used it for this purpose or knows about it, please let me know.

Ah, I see there is a similar thread on this subject active already, my bad.

A lot of halyards are a spectra dyneema blend. Kevlar does not like to make sharp bends.

I have used Kevlar for some halyard-like applications. It is very strong, and has minimal stretch, but it doesn't like going around corners real much (so avoid knots and small diameter sheaves. If it breaks it tends to break catastrophically and without warning. It doesn't take UV too well, so use a double braid with a kevlar core for the strength and a polyester cover for UV protection.

I use it, currently for my spinnaker pole sopping lift. I would not use if for stays. PBO or perhaps might be the go for synthetic stays (but I'm no expert).

I think if I do use synthetic stays I may use this - Amsteel Blue Synthetic Winch Lines but get them to put the chafe protection all the way up, though I may just use it for the shrouds.

We have worked out all the bugs in the synthetic rigging. Dynex Dux has everything you are looking for. 1/9th the weight and better strength over SS. Colligomarine.com has a lot of good info.

You can also do a search on this forum under Synthetic Searunner, and synthetic rigging I think.
