Plasma rope
 

Anyone use plasma rope Cortland rope company for standing rigging. Heat treated spectra. Got a quote at 2.33ft for 7/16. Way cheaper than dux. It's heat treated but not pre stretched like dux.

Would this be good for standing rigging. Its a westsail 32 with marconi rig. Currently boat has 9/32 1x19. Thinking about using 7/16 plasma (23000 pound breaking) with closed hd thimble on turnbuckles. Was also thinking using deadeyes technique with seizing at the top of mast to allow for stretch or creep and tensioning with turnbuckles at bottom of mast.

Any thoughts would be appreciated

Comparison
 

Hi,
Cortland makes great rope, in my experience, but their plasma might not be ideal for standing rigging. For one thing, at 23,000lb break, it is about the same as 9mm Dux or HSR. 7/16" is rated at over 31,000. This makes for a higher relative load, thus more creep.
Next, even if it is the right size for your boat, the lack of prestretching will be a problem, and a temporary lashing, if that is what you are proposing, will be a needless bother. But if you can pretension appropriately on the ground, before splicing the second end, the set might not be an issue, and you can just hook up directly.
This leaves the question of size, and 11mm anything HM seems too large to replace 9/32" wire. Maybe 9mm, maybe even 8 would be better.
Fair leads,
