Knot for Attaching Bridle to Rode

I like the idea of having a separate loop of line and tying a klemheist and then clipping the carabiner to this.

Thanks again

I use Dyneema loops for this purpose along with heavy Wichard snap hooks (SWL 4000kg) that have been spliced into the dedicated bridle lines. I have been using a standard Prussik knot on the loops and it has never slipped, but the klemheist is a variation that looks equally (if not more) secure. I use a mixed rode and the loops are used whether attaching to chain or rope.

Been using this method for about 4 years and I think it's superior to the rolling hitches used prior. It has the added benefit of letting me clip my bridle onto a rented mooring

I use a loop of webbing. Tie it to the rode (rope or chain) with a prussik knot then tie it to the loop in your bridle with a sheet bend.

Do make your Dyneema loops with a splice or a knot?

Klemheist is a good knot for taking up tension on a sheet for a winch with an over ride.

Well now that you asked: I don't actually use a loop -- I use a short length of Dyneema with an eye spice on each end, and the Prusik is tied in one loop while the Wichard shackle is attached to the other.... but a loop would be used the same. If I were to use a loop I would splice it.

The splice I use is a modified Brummel Splice http://www.colligomarine.com/docs/mi...eb_rev_1_2.pdf

If you're not into splicing you can use pre-made loops from Colligo i Loupes | Colligo Marine

If you do your own splicing, bear in mind Dyneema is slippery: Make sure you use an interlocked splice and not just a simple insertion, or add lock-stitching to your splice.

Here is the type of Wichard spring hook I use Carbine hooks Have been using these for about 13 years and never had one let loose on its own.

Rolling hitch, as others have suggested. The magic knot for this application, especially on chain. Unlike a Prussik, will not jam under load.

The big disadvantage of the Klemheist knot is that you have to have both ends of the line available. That would eliminate using a line you already have made up leading from a bow eye down by the waterline, which is what I do on both monos and cats. Even when I use a single snubber line from on deck it is nice to leave it cleated off at just about the right spot so I only have to slap it on the main rode with the rolling hitch and then quickly let out enough additional scope on the main rode to make the snubber take the strain while leaving a nice loop in the main chain rode. Don't understand why anyone would use Dyneema as part of the bridle--the elasticity of nylon is what you want.

OT, but a lot of people have very complicated bridle arrangements. You really don't need anything but a piece of line and a knot--simple, works great, no fuss.

In which case, the Icicle Hitch

You haven't tried that one have you? If yes, show us a way to tie that without having one end free (of either the rode or bridle) to put through the loop. It's a bad choice, IMHO.

That's why we have advocated using the Klemheist and Prusik with a short loop (of either strong webbing or dyneema). If you follow that advice it works perfectly and is easy to deploy, especially in conjunction with a strong snap hook or hooks.

The rolling hitch has worked well for me ,but I will try the icicle just for a change.

Very interested to know more about this:
- please can you confirm which Wichard hook you use as I can't find one that is rated at 4000kg
- do you use 1 snap hook or 2? I am imagining 1 that is attached in the mid point of your bridle. Is that correct, or do is your bridle made up of 2 lines, each with its own snap hook?
Thanks

In fact, a rolling hitch will roll and slip on chain at about 50% of the working load of the chain. This has been documented by many and I confirmed this with testing. A luggage tag or prusik is secure. Of course, the rolling hitch will not slip if the rode is never loaded that hard, which it probably won't be with a snubber until the winds top 50 knots. It also depends on the line diameter and weave.



A rolling hitch can be made secure on chain by reversing the last tuck (camel hitch).


BTW, match working load to working load, and breaking strength to breaking strength. When people mix and match it's a little weird. For example, the WWL of 1/2 nylon is about 1500 pounds, and thus a clip with a MBS of about 5000 pounds is enough (the ratio of WLL to MBS varies with the material). For safety equipment you match MBS. For bridles, rode, and things that fail by fatigue, you match WLL. ABYC doesn't even spec MBS, they spec WLL.
