If you are using conventional rope (i.e. not braid) you can thread some shock cord through it with a marlin spike. It works very well.
My wife does a variant of that and it is very successful. Your first attempt will probably look a bit amateurish, but you'll get better. It has the advantage over the big lumps of rubber that it does not add to the weight of the line which remains general purpose

May I ask what the variant is? thanks

Well, given that Gunfleet's description was not very detailed, is is possible that she does exactly the same as him... She takes three lengths of shock-cord - about a metre each. With a marlin spike, she opens up the lay of a three stranded rope and slips the end of one piece of shock-cord under. She then works down the rope in a straight line, feeding the shock-cord over and under alternately till she has it all laid in. She then repeats the process with another length of shock-cord one third of a turn round the rope and lays in the remaining length another third of a turn round. Finally, she tidies up the ends and whips them down - the result is a small bulge in the rope, but it gains a significant amount of spring. I have seen other people do versions where the shock-cord is threaded into the weave in a variety of spiral patterns - they can look more artistic, but they seem to be a lot more work and I see no evidence that they work better than my wife's simple approach.

Well, mine are not as neat as your wife's sound nor those of Roberto below. I'll have to tidy up my act! If you can get the one piece thick black shock-cord it lives longer. And using thicker rather than thinner shock cord also helps. Sorry if my description was bare boned.

I had a boat in Peterhead Marina for 4 year, a few years back, 40ft and about 8 tons. I know from experience that you can get quite a lot of swell in the marina.


I used 3 lengths of 8 strand nylon (nylon will stretch up to 60% of its original length before it breaks), for each mooring line, tied at slightly different lengths, each one slightly longer. When the first line becomes tight and stretches, the second line starts to take some load, similarly, when the second line loads up, the third line starts to take some load. This gives a progressive shock absorber effect and was quite successful. The nylon seems to absorb most of the energy, so you get very little bounce back.

I kept the springs quite tight, and the fore and aft breast ropes slack.

However, I did get a lot of wear on the cleats, so I made up some 10mm chain loops to put around the cleats to eliminate the wear and connected the nylon with hard eyes, but the mariner manager wasn't happy with the chain loops and asked me to remove them. I now keep the boat in Inverness Marina where you don't get any swell.

Does anyone have any experience using kinetic recovery ropes for mooring ?


The Landrover cross-country people round here use them, and I understand that the ropes are

1 strong

2 have an extension of 30%, and repeated recovery characteristics.

Just to be clear, I'm going to try the weaving bungy cord through 14mm Liros 3 plaid polyester. But on going on the jimmygreen site, i now see they do an elastic liros mooring warp?

I like it too, but do find conditions outside the breakwaters much more "severe" than I was used to in the moray firth, especially single handing for a day sail.

I have no experience of that, but Jimmy Green tends to be pretty knowledgeable about rope, so if they recommend it, then it is likely to be good.

Did you see the price? £161 for 50metres of 12mm line. What's that for? Mooring a dinghy? Slightly more sensible 18mm is £300 for 50 metres. When my boat was in a northern marina I was using lines over an inch thick. I wonder what Jimmy Green would have charged for them?
