I don't know why but the 2 cables on the backstay bridle is about 6" short. The PO has 2 sackles connected in sequence as an extension and even with that the the bolt in the turnbuckle is only about 1/4 through.

I was looking to replace the bridle with the correct length cables but also wondering if it is possible to use either additional turnbuckles where the bridle meets the transom or having short cables made for this extension.

Any thoughts? Anyone have a spare bridle set up?

Do you have a picture? Did you measure the forestay to the length of 31'10" Sounds more like the forestay is short than the backstay is. If you verified rake, and forestay is to length, then it might be time to get a backstay of the right length. I don't think you'd hurt anything with extending it as it is, but the "strength" might be somewhat of question (chain being only as strong as the weakest link and all).

I measured the forestay before standing the mast and it was 31'10" pin to pin. The bridle cables measured 5'2" and I read that the C25 lengths are 5'8".

How do you post pics on this site?

My bridal cable is 5'-8" plus or minus (mast is down and I could not straighten cable fully).

Thanks for the instructions for posting pictures. I have some to post on a few discussions and will work on that this weekend.

I believe the 5'8" measurement to be correct. I don't know how this occured on this boat but I did find two alternatives. CSJohnson has a stay extender that has a 1,600 lb working load or I can just have two new cables made.

Here are the pics to my current backstay configuration. After reading the specs from CSJohnson catalog I am curious if the correct Tang is being used. There is a larger tang and there is also a design out there that uses two plates with the cable "eyes" connected between them instead of using the forks as shown.

After reading more about the "flaws" of the orignal backatay not providing enough adjustment I am wondering if a PO at some point rigged it this way so he could tweak the backstay to get more adjustment when he pulled on the backstay.

There is not a one desing fleet here so it will be raced PHRF when raced. Is it worth changing the backstay rig other than eliminating the shackle configuration?



These are the shackles that are being used as an extension.



This is the backstay car.

I would be apprehensive about the shackles at the transom. They should be beefier like the one at the split. Those shackles are not built to take the strain there. If you lose the backstay you are at risk for losing the mast. Ask a rigger about extensions.

I replaced all the rigging as the original tubular turnbuckles were in place when I purchased ABRAXIS six years ago and found rust at all swages. What I replaced had 8" turnbuckles at end of backstay and on ends of bridel.I replaced ALL turnbuckles with open bodies as I like the look and feel better about having cotter pins that I can readily see, than nuts on tubular ones.
