The jib sheets on our Catalina 42 were hardly new when we bought the boat 11 years ago. They might be something like Samson Trophy since they are a bit soft and fuzzy or maybe that's because of the age. Since we are cruisers not racers (unless there is another boat in sight) super low stretch isn't important. I am thinking of Samson XLS or Samson Trophy. They are about the same price from Defender.
I don't want to repeat a mistake like when I went with New England Ropes' Sa-SetX for the halyards. The stuff was low stretch but so stiff it was like working with rebar. It wouldn't even stay in the self tailer on the winches. After 2 seasons I finally got happy watching it go away at the local swap meet. Recommendations for the genoa sheets anyone?
