Makes perfect sense. I also tried using the Estar bend knot 18:39 for tying dyneema and it works. It did not slip under a 5 ton load in 6mm Acera dyneema. Good knot to know.
Wilding Mark has to figure out how much tension to put on his wharram Pahi mast rigging. Dynema is used more on larger performance boats... but ive got a feeling its going to become more common given the cost and performance advantages over Stainless and galvanised Steel rigging especially when it comes time to replace the factory supplied rigging.
Thanks Clive! Yes we were amazing at how affordable an option it was as long as you are prepared to do a bit of the work yourself. A huge bonus is that we can repair and replace our rigging in remote places should it wear faster than we hope. -Cait
Mmmm I have noo idea. It's meant to be 1/2 diameter ×100. Math is normally my strong suit lol. Bearing in mind that is for a bury on a brummel splice, if you are going for a long bury splice then I would recommend 74 times the diameter. -sam
Ooops, sorry I meant x 100. Did you see that from one of the rope manufacturers, a rigger, or who? Has it been tested to destruction? Starzinger in his testing found the locked splice was weaker than the long bury D X 50 because of the sharp discontinuity of the fibres in the lock, where he says, stress risers affect the fiber strength. Sort of like the bend radius consideration. He points out that would only be relevant in high load use cases. I was researching this for building our dyneema Jordan Series drogue. It was recommended to not use a thimble, even a gusseted thimble, because of the huge tearing forces at the throat with the dynamic loads. So we did Brion Toss long buried eyes with the sections cow hitched together. This was break tested on a hydraulic rig used to test break strength of chain and lifting equipment.
The bury was recommended by a rigger friend but i did a bit of my own research aswell. I am unsure if it has been tested to fail. On the tugs we use the long Berry splice as it does retain its strength better and In some cases we use the splice until failing (most the time it will part on a bend or chafe point). With regards to rigging it isn't about the breaking point but more about elongation. The breaking strain of our 16mm dux is 37.2t but if we end up putting those kinds of loads on the rigging then we would be in some serious trouble. It is for these reasons we were happy with the locking splice (even though it reduces strength) over the bury. -sam

Very informative
Thank you!
Thank you Sam. Really informative and I learned a lot
Thank you so much Brad!

Hey Rob,
Yes we are very happy with it so far. Hopefully the load test on the winch (16t) is the most load that we will see in the rigging.
-sam
Nice job walking us through the process. Thanks
No worries I hope it comes in handy to you one day. It's made a major difference to our approach to lots if things on board not just rigging.

WAHOOO!!
Where did you come up with 1/2 Diameter x 10 for the bury?
Mmmm I have noo idea. It's meant to be 1/2 diameter ×100. Math is normally my strong suit lol. Bearing in mind that is for a bury on a brummel splice, if you are going for a long bury splice then I would recommend 74 times the diameter.
