Hi,
I would like to be able to connect a block or a D ring to my backstay at about a height of 3m to connect something (light). Does anybody know if there is something I could easily use to "snap on" the standing rigging cable?
So a sort of clamp with a ring I connect something at?
I don't seem to find something like this and I don't know a good name or description for it either...
 
I’ve been looking to do the same thing. Whilst there are various clamps and the like, it seems they may deform the wire and/or cause corrosion. A piece of line attached using a prusik knot might be a better idea.
 
My backstay tensioner consists of a tackle that draws the twin backstays towards each other.

I used s/s bulldog clips to seize s/s rings to the backstays.

The blocks of the tackle are attached to the rings.

I wrapped some self-amalgamating tape around the stay and whipped a stainless ring to it with some polyester thread.
Cable ties would have been quicker if they 'fell to hand'.

Looking at your photo, Poignard, i have to wonder whether you have shares in a cordage manufacturer. ;)
 
A tight lashing using nylon fishing net twine, so each turn can be stretched tight as it is put on. Has worked well in a lot of different applications on my boats. The black tarred twine lasted for years, far longer than cable ties.

The way this is normally done for twin backstay tensioner is two pulleys running on the backstays joined together - and then pulled downwards to tension them - or a more expensive type like this Barton Wire Rope Backstay Tensioner Block 50mm 91040

Avoids the need to attach blocks to a fixed point in the stay and therefore stronger / less damaging.

Well, all I know is that it's lasted 26 years without damaging anything.

Oh, and it works.
 
Depends on what level of robustness you need.

Take a simple swage fitting slice it down its length, open to fit over back stay and then crimp it onto the wire. As the swage might be quite large in diameter you can simultaneously swage a fitting to the back stay.

In terms of actually fitting the swage, use main halyard or topping lift to replace backstay. Use spinnaker or Genoa halyard or topping lift to ascend mast, remove backstay and work on the backstay at deck level, much easier to make a decent job.

A line tied by your preferred knot will work if the light doesn't need to be in a fixed position. If it does - eg a nav light, a clamp like The ones Poignard uses, or something like this

would be better. I used one for my ensign block for years.
