Chain to 3 strand nylon

[Boathook]

Is there a splice for joining chain to 3 strand nylon rope?. I know that you can do it for ocuplait? rope but I do not want to replace my existing anchor warp and the thimbles, shackles etc. linking the 2 together are a pain on the bow roller.

Several,,,,,, but you'll need one of the books. Try one of Brion Toss', he knows what he's doing.

The chain splice isn't any more difficult than a normal eye splice in 3-strand. Try the instructions listed here.

The chafe protection around the chain is propably a good measure but as long as the splice is inspected regularly isn't critical.

Modern nylon tends to come unraveled pretty quickly so some wraps of masking tape around the seperate strands makes life easier - you can tear it off as you make the tucks. Also making eight full tucks and then taping the whole splice so it passes through the hawse pipe is much stronger and easier than making a tapered splice.

Jimmy Green Marine has a nice little booklet that explains it all in detail, he's down in the west country somwhere but he has a web site jimmygreen.co.uk I think
Good luck, I did find it took a long time.

Thanks to all for the replies. The site given by Alex Rogers seems very good and the pictures clear. Next task is to try it!

Hmm,,,,, trouble with the splice at http://home.cogeco.ca/~mquill/chain_rope_splice.html
is that if the nylon is the right size to match the chain then passing three strands through the link probably is a non starter.
Better to use the "shovel" splice I think. It's simpler to ensure that each strand takes it's fair share of the load. Mine is fine after five years, though for peace of mind it might be best to remake it from time to time.

Three strands of 16mm nylon easily fit through 8mm chain. Check

http://www.ussailing.org/safety/Studies/1994ropechainsplice.htm

for a strenth test of this combination and this splice. Their tests seem to suggest that this combination is pretty well matched - all the rodes tested ultimately broke where the splice was turned around the chain but this occured at almost 90 percent of the ultimate strength of the nylon and the chain and anchor shackle were all stretched by then.

Like anything else it comes down to what you trust.

"Three strands of 16mm nylon easily fit through 8mm chain."

Interesting... I must try a few combinations of rope/chain sizes when I get the chance. On my own boat I use 5/16 chain and 12 mm rope. I managed to get two strands to lay fair with the third 'long spliced' down the rope, but three was too many. Brion Toss claims that system, with two strands in and two out is as strong as it needs to be, but I'm more comfortable with a well siezed shovel splice.
More investigation needed it seems. Mr Editor, how about it?

Hunter Boats...

supply their cruisers with an anchor chain that runs onto octoplat. However it is not a backsplice, which to me looks rather alarming in that it uses the unravelled strands over the same single link, but it is a long splice running along the chain for about eight tucks. This can be modified for three strand by tucking in turn from the seizing point around the chain into successive links. The advantage here is that the windlass combination gipsies can cope with the changeover when operating at moderate tensions very well and with minimal slip.

Our Bavaria 42 came with the rope just tied on to the last link by the (Slovenian) fitting out dealer which of course just jammed in the hawse pipe from the anchor well. This resulted in my son's (ex- Scout Association National Team member) doing a rapid chain to rope long splice in Simi harbour (Dodecanese) on our maiden cruise when we needed everything out and some after we discovered how deep it was there for stern-to mooring.

Re: Hunter Boats...

PBO January 2001 had an illustrated article showing how its done.
the finished job looked neat and tidy.

What is a shovel splice? There's always time to learn new ones!! It's all very interesting as my chain is 8mm and the rope 16mm so has someone been watching me .......
