Synthetic rigging has been used on many boats and work well. Layline will make it for you. The key is your eyesplices. Will it break sure. I am not sure I like giving up wire for weight in this case but I have thought about putting it on my boat. My class rules ban it so I will not make the change.



Manufacturers SWL's and breaking strengths are just indicative numbers. I take them as an indicator.



This last summer I was out sailing in a steady 20 mph wind with gusts to 25 + when the jib halyard snapped. The halyard was 5/16 Amsteel Blue. It had a tensil strength of 13,700 pounds. I didn't think that would happen.



Change your battens to foam and the mast tang shackle to titanium, and get some high tech sails then wires to synthenic. It cost a lot of money and unless you are one-design racing no real return. Best thing is to have good standing rigging.
