including the fiberglass, but not the wood?

Actually, the zincs will help protect submerged wood on a boat. It is
subject to some galvanic corrosion also.

really? wood becomes the anode or the cathode? I guess I have never seen a
battery with wooden plates before.

Appears the galvanic corrosion of a wooden hull comes from the nails, bolts,
screws holding the wood on to the subframe.

Every time you post you show how much you have never seen and how little
you know about boating subjects. Tell us all about your wooden boat
experience Jax ... oh, judging by your post above I guess you already did.

Tell us all about your wooden boat
experience Jax

I built a professional Class A/B Racing Runabout the winter I was in eight
grade. Except for the screws, it was all wood.

ricky, you *still* didn't answer my question as to whether the wood is anodic
or cathodic, nor did you tell us where one might see a wooden battery.

do enlighten us with your vast knowledge of uncharted facts.

My understanding is this: Wood is neither the anoode or cathode -- or
rather it is both.

To diverge, brass is a combination of two metals (copper and zinc,
perhaps.) The two metals will corrode each other in salt water. Little
pockets of zinc corrode with little pockets of copper. It
self-destructs. It is not just cannabalistic, but self-dissolving.

Wood has various components as well. It is possible that these
components will self-destruct. The amount would vary with the type of
wood, age, finish, and many other things that I don't understand. If
this explanation is not correct, then the suggestion that wood undergoes
electro-chemical degredation with near-by fittings, fasteners, and
such-like is certainly a possibility. If this were true, it would
certainly

I seem to recall reading this in a sailing magazine in an article about
galvanic corrosion. I may be in error. This discussion is not one that
is important enough to me to research. Do you know of any authoritative
sources that you can reference? I have about 3 feet of old Wooden Boat
magazines that you can have for free (you pay shipping) if you want to
look through them. I am sure that it would be covered there.

Some people seem to consider some of your comments, such as "I have
never seen a battery with wooden plates before." to be unhelpful to the
discussion. It does convey, if nothing else, a certain impatience. For
your own benefit you may choose to change your tone slightly. Even
throwing in a few smilies :-) would change some people's reaction.

tom, my irritation is with those who ignorantly or often time very deliberately
give out false information as fact. If you wish to believe that mounting zincs
on a wooden boat will inhibit corrosion, well go beleive it. BUT don't pass it
off as fact because you seem to recall maybe reading it once somewhere in a
magazine written by tradesmen.

Do chunks of trees floating down rivers suffer "galvanic" action once they
happen on brackish water?

Not really a battery per se, but the wood does get eroded.

Especially if a wooden boat is overprotected, the more noble
fitting creates sodium hydroxide, which eats away the lignin in
the wood. This chemical process leaves only the spongy
cellulose fiber behind. You'll often see a white powdery substance
around the wood. Don't eat it or snort it

Lots of woodenboat owners don't bond their through hulls together
and certainly don't put a lot of zincs on the boat.

Everyone who knows anything about wooden boats knows, Jax. You continue
to show that your boating knowledge is pathetic, your knowledge of
wooden boats is nonexistent and your attempts to trash the OP based on
your own ignorance clearly shows your only role here is that of a troll.
