i an extremely happy now after replacing the existing S/S wire life lines with 4 mm dyneema. Could actualy go to 5mm. It's so nice walking on decks with this product rubbing apon ones legs.

Looks good and easy to do ie no swageing etc but I believe dyneema is not UV resistant to any great degree.

You might do a cost analysis between stainless wire and dyneema as to how often each needs to be replaced.

Certainly dyneema is easier on your legs when you need to lean on it hard.

10 years, best to do it in silver rather than black. Will be intruduced soon to most racing catogries.

I'll believe it when I see it, I won't be changing until I see it in writing...

I replaced mine after 5 years, not from uv but a bit of rubbing from 1 eye in the staunchion. The uv resistance has proven much better than initially expected. Seeing more and more standing rigging professionally done in dyneema.

Even with stainless steel lifelines, a handy tip is the idea of lashing them to the pushpit with dyneema. If you need to get back on the boat in a hurry with an inflated pfd, it's much easier to cut a dyneema strop on the lower lifeline than try and jam your way underneath.

Dyneema type ropes claim excellent uv resistance. Anyone had any other experience?

SK75 is supposed to have high/superior UV resistance. I don't know how that's quantified though? My rigger used it on my backstay, so there must be some confidence in it.

My backstay is dyneema silver possibly 10 years old. It depends on the quality apparently . The stuff we used was from Germany . Works out about $200 top and bottom rails not including labour for a 42 foot yacht. The bits and pieces for gates and attachments are a cost also the the correct Staunton posts which I have just replaced 10 with 12 new ones will help. Also the gate fittings by Bluewater seem very good quality and hides the splice.

If you are worried about UV just use line with the cover. I have seen plenty of boats with lifelines with cover. I may be wrong but some Dyneema has a UV protection applied and some doesn't.
Dyneema is also great for a second Jack line. Have a normal webbing jack line and a second dyneema one so people can pass each other when clipped on.

We have had dyneema lifelines on Defino for a year now dyneems has excellent uv stability , i inspect it every few months so far i m happy as it looks great and no stained fittings i used grey 5 mm sk 75
