Inter 20 question and help

Was doing some boat work this weekend to get it ready for the season Of course as I was tightening side lines on the tramp I snapped the line. I have the newer style system with the screws along the hull. Any how the question is what is the proper line to use as a replacenent. I have some 2mm Marlow that I use for the jib halyard but it seems to be a bit small and not sure if it will handle the loads once I really start cranking on it to get the tramp real tight. Old stuff looks like it may be 3mm but I don't know what the line is made of. Whats the recommendation ???

I use a 2mm dyneema line.

Your twisting my arm with this I20 talk.

I may just buy one this season. The I20 classic that is. Depends how my back surgery/injections go.

I used some tiny Vectran but had issues with it sawing through the nylon webbing on the trampoline. I later switched to 1/16" Excel Vectran Marlow and it's worked and held up very well. That would be my recommendation.

Chris's boat is for sale.
