Q: Things to look for when purchasing a used aluminum (motor)yacht?
Hi all,
I already know that when buying an aluminium yacht you'd better check carefully for any electrolysis/galvanic corrosion, but are there any tell-tale signs of such corrosion? Where/how to look? I'm also a bit confused about how to electrically measure whether electrolysis is taking place. Should one look for a voltage difference between a zinc anode hung overboard and the engine block? Also I suppose there is no necessity to carefully keep a paint cover on aluminium given? Are there any other aluminium gotcha's? Finally, I hear that aluminium has a bad reputation in terms of noises when cruising, is that limited to thin hulls for smaller yachts or not? Thanks for any input, my real email is amulder(AT)rootshell.be |
