I have a shroud that needs attention. Can this be re-threaded?

Is that the shroud side or the deck side?

Screw threads can be re-formed with a die that you can probably buy at Lowes, but they won't be as strong as before.

On a properly tuned rig, the upper shroud and the forward lowers are the most heavily loaded. The aft lowers are the least loaded. So, one consideration is which one is it? I'd be less concerned about an aft lower than the others.

Personally, if it's an upper or forward lower, I'd replace it.

I like you hate to throw away a perfectly repairable item, since you can get a new swage fitting. That would be my first shot.

well upon closer examination I see I have other issues with the standing rigging.
I seem to have a forward rake on this 1980 C25. was this normal?
Also the back stay is adjusted all the way in...

I am thinking that the cables have stretched over time and time to replace the standing rigging.

Well for starters your forstay is supposed to be attached to the Tang . Probably was moved down to get some adjustment room on the turnbuckle. A mix of open and closed turbuckles tells me someone replaced a few stays, Some new and some old. If it was my boat I would bite the bullet and get a new set from CD. Their sets are excellent and fit perfectly when I did my boat.

THANK YOU! What about the forward rake? That was something I just noticed this morning. This is a standard mast. Can I just order the standing rigging set and be sure it will fit our 1980 C25? All the turnbuckles are in rough shape.

A forward mast rake isn't normal.

A couple of my Catalina 25s lower stays were replaced, but most of my standing rigging was original after 23 years on a fresh water lake. Nevertheless, it was not stretched noticeably. I don't think stretch is much of an issue. If a cable is too long or too short, it is more likely that it was either cut wrong or that some prior owner added an extender for some reason.

I suggest you examine the forestay and backstay carefully to see if there's an extension in it somewhere.

When I bought my Cal 25, I found that the PO had a short backstay made for it, and installed an extension in the forestay, and I had to remove the extension from the forestay and add an extension to the backstay to get it right. The result was that the mast had a huge rake aft and the boat was deathly slow and had an awful weather helm.

Also, I suggest you disconnect each cable one at a time, completely unscrewing the turnbuckle barrel, and then start threading it back on at both ends at the same time. Over the years, as people raise and lower their masts, they get the turnbuckles out of adjustment and it reduces their range of adjustment.

I ordered this year from Catalina Direct, replaced all my standing rigging for my standard rig Catalina 25. All except the back stay were correct, because my back stay was split and with the pigtail...the back stay sent didn't do that.

There is enough adjustment with the new rigging and new turnbuckles to tune and rig the mast anyway I wanted it, straight up, mast forward or racked back.

My full standing rigging suite from CD was a perfect fit, and included top-notch bronze open-body turnbuckles. My rigger, who installed it, was impressed, and had already told me he couldn't compete with the price if he made everything up for me. If you have a split, adjustable backstay, CD can provide that in place of the single. It appears to me it's time. (Peace of mind is worth something.)

The kit from what i am seeing doesn't come with the backstay. Then, we have an option whether to split or not to split, that is the question. OR. Is this even an option? If it isnt split right now, do we want it split? So nice to ditch that pigtail....You folks who have C25s really help me and I appreciate your time to respond#128526;

A split backstay enables you to adjust tension on the backstay on the run. Contrary to popular belief, a backstay adjuster on a masthead rigged boat doesn't make the boat point higher to windward. It makes the boat sail faster when off the wind and in light air.

You have to have a fairly sophisticated understanding of rig tuning to benefit from a backstay adjuster. If the rig isn't tuned correctly for use with a backstay adjuster, then the backstay adjuster won't work correctly. If you're motivated to learn about rig tuning, then a backstay adjuster can be a useful and interesting control. If not, then it will just be frustrating.

A split backstay doesn't eliminate a pig tail. The way to do that is to rig a simple topping lift. If you replace the standing rigging, it would be easy to rig a simple topping lift.

Thank you. I will just leave the the non-split backstay on the boat the way it is. The boat has a topping lift and a pigtail which is a piggy PITA....

...especially the first time you forget to unhook it before you fill the sail!

CD doesn't offer it on their backstays.
