I am restoring a 1974 oday22 and I need to make new standing rigging. What cable can I use ? EG, galvanized, stainless steal, what breaking strength ? Thank you all. Alan

At the very least
you want to use stainless steel 1 x 19 material. SS may be rated at either 304 or 316. Either would likely be acceptable. Do not use 7 x 19 as that is meant for running rigging such as wire halyards. It is more flexible than 1 x 19. As for thickness, check the old rigging if you have it. If not, a good safe starting dimension for a 22 would be 5/32". The original may have been 1/8" but it is never a bad idea to upgrade slightly. If you go bigger (bigger is not always better) you may be adding excessive weight aloft. Do not use galvanized wire. It just does not meet the requirements for a sailing environment. You said you need to MAKE new standing rigging. This is very difficult to do for an amateur. Having the terminal ends professionally swagged it typically cheaper than it would cost to purchase the necessary tools to do the work. If you have the old rigging, send it in (properly labelled for each stay) for replacement. The rigger will measure from eye to eye and replicate exactly. You may also need to replace turnbuckles if they are of some age as well. Perhaps someone with an Oday 22 can pipe in with the exact thickness of the stays. I am referring to my Sundance 20 and DS II that I had prior in making the recommendation of 5/32"

I plan
I plan on doing this soon, and I'll probably order 304 stainless and mechanical connectors from an industrial supply website. The only problem : i want to upsize, but that also means i need to enlarge the holes in my chainplates by 1/32" - safe?? It seems like it should be. I also would like a new forestay upper end, not a T-ball. any suggestions!? It may even be good to drill out those stress cracks that may or may not be in the chainplates?

thank you
Thank you for your replies, I do not have the old rigging, what this is ,is an oday22 HULL in great shape but I have another older boat the same size and I wanted to use my running gear on the oday. My mast is 24' tall and the cables on my mast, I am sure may be to short for the oday as it's cabin is much taller than my boat. I know that the oday had a slightly shorter mast but I think this will work. Alan

To correct several things so far written here.
1. Galvanized wire rope will work just as well as stainless steel but it will not last as long before it starts to rust. 2. The difference in weight between 1/8 and 3/16 wire rope is so small as to be insignificant in that 1/8 inch wire weighs 20 grams per foot and 3/16 weighs 40 grams per foot so a 28 foot stay would come in at 18 ounces for 1/8th inch and 42 ounces for 3/16. the difference being about a pound and a half. in the total length. 3. You can make up the standing rigging with galvanized wire rope and U-bolt clips and it will work very well but will not look as nice as swagged fittings on SS wire. If you keep the galvanized wire coated with pine tar and varnish it won't rust.

Ross- I enjoy your expierence and your recipe for goose fat pastries, but pine tar and varnished galvanized rigging with u-bolts is an image I will never forget. Merry Christmas Rob Hessenius

Rob , Look at the work boats. I could rig a 30
footer for a hundred bucks with galvanized wire and cable clamps.
the discussion the other day was when is a sail boat a yacht? I can tell for certain, NOT when it has galvanized standing rigging. ;D But it will serve. Some folk here believe that getting underway is most important.

I agree with Ross....As usual
I work offshore on the Platforms and Rigs. Although i am not a rigger, I dont recall ever seeing S/S cable on any rigging. Same goes for shrimp boats. Also correct me if I'm wrong, but isnt the normal galvanized wire you buy from a rigging shop stronger than S/S? Tony B P.S. We are talking about a 22 ODay, not an open ocean racer.

Funny thoughts
Guys- I'm not trying to argue with the properties or usefulness of galvinized wire. When I read Ross' post it put images through my mind that made me laugh. I don't get to see too many workboats or platforms up here where Im at. Rob Hessenius

Rob, It is funny because we develope
such a mind set about what CAN be used on a boat and lose sight of the purpose of the components. Some of the high-tech synthetic lines are as strong size for size as wire rope but they aren't noted for their resistance to chafe. I often use a lashing in place of a shackle. I use galvanized turnbuckles. My large cleats are black locust fastened with 3/8 inch galvanized carriage bolts. My standing rigging is 1/4 Loos brand 316 stainless steel 1-19 wire with sta-lok fittings. I have seen boats rigged with 1-7 galvanized strand such as the utility companies use for guys and messenger. The neutral on the drop from the transformer to the house is strand.
