Hi folks, just broke my forestay... anybody out there using Dyneema rigging for forestay or shrouds?

p.s: I have an old DN, use it only for cruising around. Old straight alu mast. Old style mast hound. I find that the rigging thimble and swage type ends tend to fail rather quickly. Can you suggest an alternative for a limited budget guy, out of a job waiting out the Covid crisis?

Thx, regards, Pierre J.

Go with 5 mm Dyneema,put some loop splices in it.Use a thimble or splice a cover over the loop.Shackle it on and your good to go.

I've tried... it will creep and stretch for sure. HSR or annealed dyneema helps. If you have some splicing background adjustable eyesplices can help if you start running out of throw or range.

Chad have you tried pre stretching it before using.I think the biggest stretch comes from the splice itself.
Also I would think there would be very little stretching or creeping on the side shrouds.Probably could get away with 2.5 mm side shrouds.
Nice easy economical way of running rigging for a cruiser.

If you are getting repeated failures near the swages or nicopress sleeves you may need a toggle on the end.

Don't most riggers have a junk barrel?  I've found really good stuff in the dumpster at my soft water club.  You just need to get over the embarrassment of dumpster diving - it wears off when the wire if free.
