    Even tho I Live in the land o lakes, I have always been a landlubber,lol... Not afraid of the water or such as I can swim like a fish, but I prefer the dry land for my travels and adventures.

    I have went down rivers and creeks on rafts and such. I enjoy fishing in a boat and such, but there are far more things that interest me that are on dry land.



    The reason that I decided to post on this topic is that I didn't have a clue about the subject before I read over this thread. I tried looking up some information on these Zinc Anodes and from the little I read it seemed that these are only used in salt water, and not needed for the waters of the lakes of Minnesota?

    Was curious about their use. I did read about the electrical charges and loss of metals and such and I have a understanding of those processes.

    Can you give us landlubbers a short coarse on their uses and applications for our curiosity?

    ,Aluminium, Magnesium and Zinc all have uses as anodes in galvanic protection, I'm not well versed on this topic but will give it my best shot from what little I have learned over the years.

    Hot water tanks used in industry or home have anode protection, to extend the life of the tank these should be replaced every couple of years. From my experience those anodes are made from either magnesium or aluminium.

    Galvanised metal ware, specialised structural steel for example high tension power towers and chain link fencing has been dipped in molten zinc.

    Zinc anodes used in concrete affixed to the re-bar, underground tanks and pipe lines.

    So yes I would say your boat even if used in fresh water would benefit from the use of anodes, itis just that the galvanic reaction ( deterioration ) of the anode is not as obvious had the boat been in salt water.

    When you have a galvanic reaction taking place you have the production of hydrogen, hydrogen causes embrittlement in metals which in the case of an aluminium boat may account for those cracks forming as the boat ages. Protect your investment install anodes, car, boat trailers that riding lawnmower you cherish.

    If your boat is made from aluminium, the boat with out the more reactive zinc anode has become itself sacrificial.

    That lawn mower sitting over long periods without use the aluminium piston and the iron block are having a love affair by exchanging electrons left long enough the piston becomes seized in the bore. A sacrificial zinc anode would have prevented this love affair.

    If you live in an area that uses a lot of salt on the roads, use anode protection on your vehicle if your not planning to trade in your ride every couple of years anode protection regardless of slated road will prolong the life of your ride.

    As consumers we're not taught how to prolong the lifespan of our purchases other than the money lenders encouraging us to borrow money for home improvements.

    Galvanic Protection would be a lifetime study.

    On a side note, it is a well known fact chrome plating causes hydrogen embrittlemnt, parts such as a tube front axle and leaf springs used on that T-Bucket roadster are now prone to forming cracks leading to failure.

    Anodes used in concrete.
