Standing rigging

Hello all,

I am considering changing the rigging, it's perhaps 40 odd years old. I did not find any corrosion or broken wires at deck level, but have yet to go up the mast. I am considering pre-stretched or heat treated Dyneema, or similar product, regular swage and SS wire, or perhaps Norsman style fittings. I've ruled out the old galvanized wire methods.

Does anyone have any experience they could share in this regard?

Thank you,

Greg

We used 1/4" 316 stainless on the lower shrouds and 9/32" 316 stainless on the forestay, backstay, and upper shrouds.
I did Norsman style fittings on all the deck height fittings, as it is possible to disassemble them and check for corrosion.
On the recommendation of several riggers, I used swage fittings for all the upper fittings, as they are not subjected
to the continuous bath of salt water, and the water drains away from the cable/fitting junction, which greatly
decreases the chance of water inrusion.

Hi Ed,

I appreciate the advice. Can you let me know where you purchased the rigging? I am getting wild price swings. I'd rather go with a known supplier than throw a dart at the internet and hope for the best.

Did you also replace the chainplates?

Thank you for all of your contributions. I enjoy reading your posts.

Best,

Greg

Our Marina is a working boatyard and the (late) owner was a master rigger, so I had them order the wire.  Might have been from Rigging Only, but I honestly don't remember for sure.

I inspected the chainplates and ended up replacing one of them that showed signs of leakage and a bit of corrosion.  Probably should just go ahead and replace the rest of them.  It wasn't a hard job.  I just took it out and had a local stainless fabricator duplicate it, as the holes were hand drilled, so not precisely lined up on anything.  They're just flat bar stock with no bends.

When reassembling, be sure to put the bolts thru the chainlpate first so that it rests on the unthreaded shoulder of the bolt.  My mechanical engineer friends tell me that resting on the threads causes stress concentrations which can lead to cracks.

Ed. Thank you, I'll pull one and have 6 made.

Thank's again.

Greg
