Mast corrosion Swan 47/59 Hello, We are replacing our rigging and have taken the mast of. The yard has warned us that there is little corrosion at the bottom of the mast. He is proposing three solutions to be discussed: do notthing, cut 2cm of the mast and option1: put a plate 2cm thick below the mast, option 2 introduce in the mast an aluminium protection with rivets. Anybody with experience in this matter? Ludovic |

I had a similar issue about 15 years ago with the mast on my Swan 41. I think I went for your 3rd option which was to slieve the bottom of the mast which seemed to work very well. It was done for me by Proctor masts (now defunct) who had a mobile service unit who did a couple of other jobs on the mast and boom at the same time in the Hamble boatyard.

This is the way the mast of my 411 was fixed 7 years ago: your 3rd solution. |

Thank you to both of you, I think indeed that fitting a piece inside seems the best solution. In this case I beleive the best is not to cut the mast but probably just clean it very well and ad the piece inside. Ludovic |

Dear Christophe, After some work this is how the bottom of the mast looks like. I would not fit a staineless steel piece in the mast as you will have even faster corrosion but an aluminium piece.
I cleaned my shoe mast and did two holes in the middle so that the water trapped inside the mast can leave. I even plan to rince with fresh water inside the mast at the end of holiday season. Did you check the keel bolts below the shoe mast? (see the post on this issue)

Christophe, as already mentioned, I would strongly discourage adding stainless steel parts in contact with aluminum. Indeed it looks that your mast was already fixed and presently it does not need much intervention. |

Many thanks to Daniel and all for your valuable comment. As far as the bottom of the mast is concerned, we will take the existing paint and rust away, see how the aluminium is, once cleaned, and hopefully repaint it without more to be done. I still have a question on the piece of metal which lays underneath the shoe mast. I have attached some pictures which show rust. We will sand it and clean it but I am not sure this will be enough to do the trick. It seems that removing this piece of metal is quite a job. I was wondering if any one of you has had similar experience or has any good piece of advice for me. I have liaised with Nautor Spare parts to find out if they can still provide a replacement of this piece and am still awaiting their response. Best regards. Christophe |
