Some really good vids on YouTube that will make you smile
Patient ..step by step

 

I have looked into it. Found no videos or instructions for this type of rope.
Also nothing in the two booklets that I have here about splicing. If you have some links please share.

 

I have learned they call that a twill-pattern technology for the cover. It is one-on-one and pretty tight. Not sure it is spliceable

 

Climbers would not splice a rope. Would tie a figure 8 on a bight near the end but I don't know that you'd ever want a permanent loop. You might try the arborists' websites as they have quite a bit on rope techniques.

 

The problem is the cover. It is many times tighter than yacht braid and a bastard to open, but not impossible. But no one does it because it is too much hassle, especially for a snubber, which is a wear item anyway.

Knot or sewn splice (industrial tethers from dynamic rope are always spliced). It's going to fail due to chafe or fatigue, not at the knot. In fact, knots have very little effect on fatige life, because the first turn in the knot (the weak point) does not expereince load cycling or movement.

So figure 8 knots, like climbers do.

 

Thank you. I just read your book. That's what prompted me to make a longer snubber for my boat. I am a climber so I retire a 230 foot climbing rope every year.

I bought some dyneema and found tutorials for tying soft shackles. I'll try using this at the chain.

 

Another reason splices are not used on dynamic rope tethers is that the length of the splice reduces the length available to stretch (the splice is very tight and double diameter).

 

More than once, I've made a winter project of splicing custom snubbers. Never on climbing rope. I've been disappointed each and every time, but it's typically been with the crazy new chain hook that I just had to try. tip..... they are all a waste of money.

I just stick with my inexpensive effortless time tested method. I buy a 3-strand dockline that come pre-spliced with a 12" eye on one end to place over a bow cleat and I tie a rolling hitch to the chain. They are commonly available in various sizes and lengths. We anchor a lot, so I just order a new one, when it gets dirty enough or chafes.

For my last buy, I actually bought anti-chafe sleeve by the foot, to stitch it on where it goes through the cleat and past the bow. I only stitch the end closest to the eye, so it won't fall off, but the line inside can stretch.

This makes a lot of sense.

A good chafe guard for less money is 1" tubular climbing webbing.

 

When I rebuilt the deck on our house I took a look at the cost of stainless wire for the rails, ran away, and used an old climbing rope. Probably not code, but working fine.

 

Are those ropes nylon or polyester? Do they have a lot of elasticity? I know nothing of climbing gear. A 77,000# boat has little in common with a 210# climber.

 

Yes, climbing rope is elastic. I think the difference in the configuration of a climbing rope would make it not worth the effort to splice. I would use my old climbing rope as a spring line or backup in a storm. Don't know I would go the trouble of splicing it though.

A 210# climber is like a 77,000# dinghy.

 

Perfect for an anchor snubber.

At least for a 14,000# boat like mine, don't know about 77,000#

 

I imagine climbing ropes would also make the prettiest dock lines you ever did see...

 

30,000 pounds is probably the upper limit for climbing rope snubbers (I know several experienced cruisers that use UIAA single rope with boats in that range). I used 7mm UIAA half rope for a bridle on a 34' cat. Very smooth, even in shallow water.
