Last outing we managed to snap the casing on the dyneema main halyard. I'd been warned that this would happen in about 3yrs, which it transpired is about right. As its the main I'm going to replace it, not end for end it like we did last time with the spinnaker halyard.

I am trying to work out the best option for a replacement.

The root cause is people not taking up the tension with a winch before trying to release the jam cleat, which is going to happen humans being humans. The case snaps where the jaws bite into the rope. But when I look at Dyneema rope options, it is all about stretch and creep and strength, there is little information about the actual casing, or cover, itself.

Is there such a thing as a tougher casing option, rather than the dyneema core, available?

Appreciate any advice!
