Running backstays ARE NOT a replacement or alternative to a permanant backstay. Running backstays provide additional support to non-masthead rigs or masthead rigs where pumping is a concern.

I'm not sure, I know I've used mil spec harware for aircraft before, and they corroded in less than a season. I'm in salt water, lower potomac.

pvanv1 Time for a new backstay. Inspect all of the rest of the rig as well. 10 years in salt is all that is reasonable from ss wire rigging.

davewild g'day Gil, I'm not sure of your rig but an S&S from the mid 70's is likely to be a mast head rig with in-line spreaders. I would be VERY reluctant to replace a proper backstay with running type backstays on such a rig. S&S were pretty good at making boats work. We had a local boat builder make quite a lot of S&S 34's around that time and they are ledgendary. A couple of notable local boats/owners are Jon Sanders with Perri Benuo(double solo circumnavigation) and David Dicks(at the time and maybe still the youngest to circumnavigate). Not a bad pedigree you've got there.

lol, ain't that the truth.
Hopefully they'll get some better coatings to protect from UV damage, as that seems to be the biggest killer of the syn. lines. I'm a big fan of the syn. rigging, I don't like paying $160 for ONE SS shroud and waiting a week to get it. That being said, I plan to keep a SS forestay, and SS uppers. Don't want anyone on the boat getting 'careless' with a knife.
