Dear Jan, it’s bad of course, but could be fixed. In case you need more and detailed pics about the reparation I did on Vanessa’s mast, please let me know. Fai winds Matteo (47/069 Vanessa) |

Dear Jan, no problem, I am traveling today but back home later tonight and I will send you more and detailed photos. Anyway when I found out the corrosion on Vanessa’s mast (March 2015), as you can imagine, I was very disappointed, and scared to death, so I consulted Franco Manzoli, who is not just a good friend of mine but even (in my opinion) the best mast maker in Italy, and by the way he owns a share on a Sparkman&Stephens Swan 41! So, he knows his job and S&S Swan!!! He perfectly advised me, and I exactly followed his suggestions (pls see above description of the job). As you can see the mast (which I did now want to change, I am absolutely convinced nobody’s build today masts as perfect as the Nautor built ones -with the unmatchable help of Rod Stephens-‘ ) is now back on its place and as strong as new! So, don’t worry, you will fix it! Fair winds matteo (47/069 Vanessa) |

Dear all S&S Swan fans, I would like to add a few comments on the above. To my opion it would be quite essential to try to isolate as much as possible the stailess steel of various pieces from the aluminium of the mast, especially since the anodisation has been destroyed by welding in what you describe. What I did on our Soeur Anne spreader fixings was to paint the surface with epoxy (2 coats at least) and adding silicone mastic before putting the stainless steel piece back in place. (Probably a polyurethane mastic would have been better.) Anyway, all this so as to avoid as much as possible salt water coming in between auminium and stainless steel. There is a link in the forum in which the professor gives this recommendation. All the best, Philippe 41/022 |

Dear Friends, of course Philippe is correct, alluminum and stainles steel MUST be isolated, there are a few very good products, one is Tefgel (the one I used) and another one is Duralac. By the way I am attaching two more pics, the two last ones, which show final result. The job was a bit complicated of course, but dear Stefan, please don't worry, I am sure your mast could be repaired and will be as strong as it was when built. I think all of us S&S Swan Owners should check our masts under the stainles fittings...! Fair winds matteo (47/069 Vanessa) |
