Mast corrosion
« on: 31 August, 2012, 18:03:14 »
On the Contest 31 (early version) the aluminium mast sits in a stainless steel tabernacle. This does not seem like a good idea with the metals in so close contact. Has anyone suffered corrosion due to this at all?

The same with my 29. However, I did check with the mast fittings (Top, Saling etc.) There was quite some corrosion going on which I stopped by isolating Alu and stainless with rubber and Tef gel using Monel rivets

So, if you have the chance to do that, check the other parts of the mast for the same reason!

best regards

Andy, the physical contact with the tabernacle is minimal and, when built right, the mast itself has a non-alu pipe to guide the mastbolt. It's a very common construction but when in doubt it's also easy to inspect and it is always possible to change the mastfoot.
