Faded stripped Dyneema splices - safe?

Dyneema has 'very good UV resistance'. Not UV proof.

The colour is sometimes mostly in a surface coating of the braid, splicing these braids re-arranges the strands and some of the coating gets buried.
The splice will also end up less smooth than the rest of the rope and collect dirt.

I wouldn't worry about it unless you are operating at much higher loads than is normal for dyneema on a cruising yacht. I.e. if the dyneema is smaller than the wire you might notionally use instead?

Hopefully you have some idea of the safety factor you are using. Without that, ANYTHING is a guess.

Many people have studied Dyneema vs. time.

I have had old Dyneema rigging break; it's all about time. I just bought the boat and it was on the to-do list. Fortunately it was non-critical to the mast staying up, but it sure went "pow." Keep track of when it was installed and accept that 5 years is about the limit, depending on the stress and how critical failure is.
