I want replace my standing rigging. Can anyone see a reason not to use Dyneema instead off stainless wire?

I think that would make more sense on a light weight trailer sailer. No more danger of kinks and easier storage when the mast is lowered. The strength seems similar/better than wire at like for like width.

I am planning to start with my back stay and baby stays as an experiment. I intend to splice it myself and have ordered a bit more which I will splice up and test for strength by pulling with my big truck.

Any views welcome.

I think a couple guys here already have. Try a search, i know this has been discussed a few times before.

Thanks Bob. I did do a search and only found people who were planning to do it, not anyone who had. Maybe I did not look hard enough, i will try again.

Don't realy think it is worth it on our boats. Except for the back stay.

Two years and two boats back (17ft t/s) I replaced the stainless steel, standing rigging with Dyneema with great success. There have been no reports of deterioration and I will do likewise on my X when necessary.

Synthetic rigging life span around 6 years due to UV exposure.

Stainless rigging life span around 20 years due to fatigue.

Average, Lots of variables that will change both of them for the better or worse.

I have changed to Dyneemaa standing rigging and used it for a season. You save weight aloft and it is more easy to take down and raise the mast. The disandvatage is that you have to have 5 mm diameter instead of 4 mm on all schrouds.
