I went to 3/8 VPC for spin halyards to save weight. The knobby surface provides good hand grip. The line locks well in the clutch.
I tried 7/16 for jib sheets and also found them a bit slippery. The other issue is we broke the core on one line earlier this year. The core - core eye splice was fine, the break occurred a bit back of where the tail was buried in what I will assume was undisturbed core. Might also line up with the Harken Jib car sheave, which is over sized for 7/16 line. I would think that 7/16 is fine for a 30-1, though we do carry the 155% up to higher wind speeds than some boats. It is a North 3Di which is considered to be low stretch. We do not let if flog but I suppose with gusts there could be shock load. I have wondered with lines that have a slippery cover if there is some issue with it sliding over the core, say as it rounds a sheave. I understand that the core effectively carries the load, but if the cover is carrying anything that could cause a stress point. I switched to Maffioli Powergrip 10 mm. So far it seems perfect. Runs nicely on tacks, lots of grip by hand and around the winch. Lowest stretch I have had for jib sheets so the trim stays constant during gusts. I spliced in an eye splice around Tylaska J Locks. Splice was OK, a bit hard to bury the cover.

I cannot find a line specification for the Barient, and when I replaced the line a few years ago, I got 7/16 VPC instead of the 1/2? that was original. Is this to be expected in high winds? I found something from Barient that said that the self-tailer was adjustable with spacers, but I can?t find that in the parts diagram I have, so I don?t know if it is true and whether I need to change spacing. I had the same problem with the Barient self-tailing winch we were using for the mainsheet which also now has a slightly down sized VPC. Is VPC just slippery and this is a characteristic of that line? Thanks- Dave Aries 1990 C&C 34+ New London, CT
