    I can assure you galvanised chain from, apparently, reputable European manufacturers has broken (bad weld), I have the images. I can also assure you that galvanised chain from sources unknown to the owner of the yacht (so second or third hand etc) has broken. I have seen galvanised chain (and have the samples) from '1st World' supplier where the there has been no match/alignment of the 2 halves of the weld.

    Don't be complacent.

    A regular contributor to the magazine and this forum suffered a broken galvanised chain this year. I cannot understand how a stainless chain can fail by crevice corrosion. The mechanism cannot exist.

    So I cut the 2 vertical pieces of pipe and sheeved them with 2 pieces of silicone pipe, when at anchor I can then remove the pipe/chain and hang out of the way. I don't have a picture of this to hand.

    So far it seems to work quite well.
    That's interesting Gary. It's not a solution to the chain pyramid that I've ever seen before.

    Like you, I would have thought that people could sleep with their feet either side of the pipe but it seems not.

    I now understand what you mean about moving the pipe out of the way of the feet but with the chain still inside it. Very good thinking.

    Richard
