Hawser pipe - anchor rope splice size problem.

[snoozydude]

Gidday

I have 12mm anchor rope which I want to splice onto my chain.
If I use a stock standard stainless thimble for 12mm rope, the spliced loop is too big to fit through the hawser pipe in the deck to the anchor locker.

I suspect there is some rule of thumb to the amount of freedom between the splice and the chain shackle.

The hawser pipe through the deck is 55mm in diameter.
Boat is 8m.

I understand a long time solution would be to change the hawser pipe to an anchor locker hatch - as I do not have a good roller to store the anchor on the pullpit anyway at present, this would solve a lot of problems..


Does anybody have any good ideas or ideas on reducing the size of the rope splice for the chain shackle.

Hi!
You don't say what sort of anchor rope you intend using. If it's 3-strand, then the only likely solution is to change the hawse pipe for one of a lrager diameter. Personally, I got over a similar problem by using Anchorplait spliced directly into the chain. This will only slightly increase the O/A diameter of the whole and may allow you to retain the existing fitting.

FWIW I splice over 14-15 links not the 5 or so normally recommended. This gives me more peace of mine though from a strength point of view is well OTT! However, it does seem to help the spliced section go round the (electric) windlass in down into the chain locker.

Cheers Jerry

split the 3 strand 6 inches from the end, pass the 3 individual strands through the end link of your chain directly and then splice back into the rode.
try to keep it tight and straight on the chain link to avoid it moving constantly and take a couple of seconds to check for wear every now and then.
total diameter will be under 30mm, pass through your hause pipe and be easy to handle.

A long splice throught the chain links is better. It best works with 4- strand or octoplait. Here the rope strands are woven through the chain links. But I can't seem to find a link to illustrate.

Chain splice

You will find this one in old ropework textbooks, as it was used for splicing lengths of chain (to take chafe) into halyards on square riggers and such.

Cut one strand out, about two feet back from the end. Unlay the two remaining asterands one foot. Pass one end through the last link and lay it up back into the contline vacated by the strand that you cut out. Pass the second strand through the link and splice it into the rope as you would a short splice.

Serve over the lot.

No gain in diameter - will reeve through a block, let alone a hawsepipe!

Are you using 3 ply nylon? If so then you shouldn't be using an eyeplice with thimble. You should slplice the rope to the chain by the back slice method. You can buy plastic heat shrink tubes to use to assist the forming of the splice. There are plenty of rope suppliers who will show you this method. Alternatively, if you are octoplait, there is a different splice which again info is available from the suppliers. Both these splices will run through your hawser.

DON'T USE the "machovec" (or Simpson Lawrence type2) type of splice.. for a very simple reason:

The radius of the rope around the last link of chain is much too small and you will loose at least HALF of the rope resistance..

Use the http://www.bluemoment.com/warpchainsplice.html

Many thanks for the replies. There are some great links for research. It is absolutely fascinating to see the use of a thimble is not really recommended with nylon rope.

Mine is 3 strand nylon.

I have been snooping around the marina looking at other people's setup and I had not seen the rope spliced into the chain using the methods described but can see the sense in using a splice.
The "bluemoment" site is a very good easy to follow illistration as well.

Thanks all

Thanks Dug..
