I went for a two hour trip into town to get some vinyl flooring this afternoon, and when I got back, my stern nappy pin had come adrift, so the stern was about 8 feet out into the canal. Given how many boats go past (especially at weekends), and that most of them don't slow down much if at all, I guess one of the pins was bound to come out- and its been three days. So I was planning to get some mooring chains with the rings, but then I had an idea. I'm imagining that the chains probably make a fair bit of noise (more noticeable at night maybe?), especially in breezy conditions, so I thought- why not use a bike security cable instead? This kind of thing: www.amazon.co.uk/dp/B07NVDQCKB/ref=sspa_dk_detail_0?psc=1&pd_rd_i=B07NVDQCKB&pd_rd_w=0hFQ9&pf_rd_p=1055d8b2-c10c-4d7d-b50d-96300553e15d&pd_rd_wg=mBQik&pf_rd_r=PCDMDSQQFTC1C9G8CH7R&pd_rd_r=913560ea-077f-4236-b6c4-2a4aa813259f&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExQUcwNDI4QzhHSlAxJmVuY3J5cHRlZElkPUEwMTE3NTk4M0ZVMkxDUExVME1DRCZlbmNyeXB0ZWRBZElkPUEwNTEzNTU4Mjg4QVhVVFNPQzNUTiZ3aWRnZXROYW1lPXNwX2RldGFpbCZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=It would be very strong but quite silent, right? It will start to fray after a time, so it will need replacing every year or two maybe, but maybe that's worth the cost for a bit less clanking at night? Is this one of my usual hare-brained non-starters, or could a bike cable be used this way? |

Yes you can use a cable.
Mooring chains are virtually silent compared to nappy pins.

Indeed it could ... but the mooring chains make no noise if you've moored tightly ... no need to re-invent the wheel as it were  Rog |

To be honest, I havent noticed any noise that I put down to nappy pins over the last few days. So maybe there is no noticeable noise from chains. On the plus side, I imagine a chain would act as a visual deterrent to scrotes and vandals, so there is that. I'm getting something though- I've lost my trust in nappy pins. |

I have two short bike cables at the moment looped together to 'secure' the ebike, so I may use those for mooring instead, until I get to Midland Chandlery near Braunston. I'll be cruising again on Tuesday so I should be there in a couple of days. |

Piling pins are fine mostly ... but if you're leaving the boat for any length of time, chains are much more secure.

Rog Fair play to the nappy pins, they held for a few days, and it is a fairly busy stretch- but chains or cable will be my default method if I know I'm staying overnight, or for a few days. |

Nappy pins are a poor choice. Chains are the way forward. Failing that, 3ft length of old rope, pass it through the piling, tie a knot in it, job done. Leave it behind when you move on, another boater will make use of it.

sometimes use nappy pins when I'm on Shapfell and to be honest I've never had a problem with them.
prefer a muddy bank and pins as GRP and pilings don't mix happily

Crane hooks. I was using crane hooks before the "nappy pin" things turned up in the chandleries and -everyone else- was using chains. Never had any noise problems and never came loose. Make sure to clip on near the bolted on bit of Armco so it doesn't jump along the piling. These hooks . You can take off the safety catch but it doesn't really get in the way actually.. www.ebay.co.uk/itm/2-Ton-Alloy-Steel-Large-Eye-Lifting-Hook-With-Safety-Catch-2T-2000KG-Tested-/142033279917 There are some pretty tasty clevis hooks around as well which will do the job too. This sort of thing:  I've used both and they are infinitely better than anything the chandleries carry. ETA just clipped over the top part of the horizontal Armco they will remain there no problem. easy to fit as well no fannying around. |

We bought two 'goat chains' a couple of years ago, and, yes, this is true, they don't make a noise, as you would think. The hooks for steel piling screech all the time against the metal as the boat rocks up and down, unless tied very, very tight.  A chain of goats. |

Another solution is to use a length of channel section steel about 2ft6, or aluminium. Get the right size to fit in the recess gap in the piling. Off top of my head it would be around 4"x1.5" but would need measuring. It wants to drop down and fit snug but not jammed in. Fix an eye or shackle to the top of it. Drop it into the gap beside the bolt on the piling, tie boat to shackle. I never made one of these but it was demonstrated by a very cool old boater and it worked a treat. Just slot it in then pull it out. 100% secure provided you do fit it next to the bolt. But that's obvious with nappy pins as well so assume everyone already knows that. Technical drawing. If in doubt ask.  Blue is the channel section Red is the piling Green is the bolt/nut on the piling* Purple is the shackle and rope to boat. *To be fair it is actually a long stud not a bolt. |

I had a chain snap on the Ashby once, someone had tied the boat back up but had been left for two weeks, you can use ratchet straps also and I have a pair for extreme conditions but they do look a bit trampy I think.

I once ratchet strapped my barge to a buddleia plant growing out of the towpath.
Got a ticket from a CRT bod for that. turns out it's in the bylaws somewhere not allowed to interfere with vegetation.
It held the boat perfectly well though.

I use ratchet straps, if you get them tight you can't even feel it when another boat comes past.
