Blocks for running backstays

[gmakhs]

I am looking advise of what blocks would be the best option for a beneteau first 26 for the running backstays, I have been looking around and I am currently considering :

And
https://www.svb24.com/en/bavaria-fiddle-blocks-with-beckets.html

If my understanding is correct that will be a 4:1 system .
Do you believe I need to go with triple blocks ??
I don't want to need to use a winch to apply extra tension .
One of my current block so I am looking to replace all of them .

I was going to suggest rings but you might need a winch

Isn't the First 26 a masthead rig? Why do you need runners?

4:1:
Fiddle on top, fiddle becket cleat on deck.

For your first 26, you might consider just a 3:1 (Make sure to order fiddle blocks with solid cleats that can handle 1/3 of the load.) The Advantage of this aporoach is less line to release and pull while gybing. Disadvantage, a tad less power than 4:1. I think 3:1 should be alright on your 26.

3:1: Single becket on top, fiddle cleat on deck.

My first 26 came rigged as a fractional with runners , and without runners I can't apply tension on the forestay .

3:1 is not enough for easy handle 4:1 will be the best .

The issue with gybing when cruising is easy solved by a reef on the main and leaving the running backstays permanent .

The runner will be on the windward side, so that jib sheet winch will be free (assuming it is not used for a spinnaker guy). Dyneema and rings with no purchase makes a clean, light implementation.

We have 4:1 tackles for the runners on our J/36. Much quicker & easier than using a winch.

Crewed racing or cruising?

I suggest a 2 X 2:1 (4:1) cascade arrangement. I have found that side by side double or triple blocks, especially with beckets, are prone to twisting under load adding binding and friction. Twisting is inherent in these designs because all the loads are not in line. In addition many types of line twist under load due to the spiral lay of the core. I like to use Spectra 12-plait braided line. It is easy to splice and resists UV. If there is a place with a lot of friction such as a cam cleat you might want to add a jacket to that section.

Note that Spectra is strong for its diameter. You may get away with smaller diameter line for your application. Just make sure the blocks you use are rated for the load.

I would use dyneema line for each back stay with a spliced eye on each end and attached to ready-made boom vangs that can be easily clipped to deck eyes when needed and removed when not. A 4:1 vang is more than enough. You may be surprised at how little tension is required on your running backstays to keep the mast from pumping.

I changed my rigging 2 years ago , paying 180 euro only for the rope (without the fittings ), and constantly worry about UV and chafe is not.on my future plans .
The post question was about the blocks , but thank your for your inputs

My FRIST285 back in Carlyle,Il (for sale) has an ajustable back stay that I put 6:1 with a cam cleat on the bottem . Easy to grab and tighten or pop it out to loosen . Worked great.

Do you have pictures of the bilges and keel connections ?? If yes will be very helpful for me .

I hi-jack the thread

I'm thinking of going with a low purchase (2:1) or non and run it to winches. The thing is...I have two small 8-winches laying somewhere. I could place these winches on wither side of my mainsail track winch (a 40 winch). Using the 8-winch initially and when more power is needed I use the 40 winch?
