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.

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

ah, someone who knows. Thanks Matt/Meribeth.

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.

Rick

so, rick, *you* -- with your immence knowledge gleaned from reading magazines
while bathtub sailing -- KNOW that zincs on a wooden boat protect it from
"galvanic action"??

maybe you might want to find out what the word "galvanic" means.

btw, yo-yo, you missed the part where zincs actually cause deterioration of
wooden boats. How did that happen, ricky, with all that knowledge you have?
Same way you couldn't tell the difference between an ag pilot and an ATP, each
of which you have claimed to be?

So Jax begins another spin down the spiral of his dementia.

Show the post where I claimed to be an ag pilot, Jax. Your fantasy life
is spilling over to your online delirium. I do have an ATP certificate.
There are quite a few ag pilots who also hold an ATP, and a few airline
pilots who do some ag flying. So if there is somehow a "difference" I
guess you will have to explain it to us.

Once again you show yourself to be no more than an ignorant poseur,
desperately struggling for attention.

Rick

....or you can do like I did a long time ago... just block his posts and
you'll never know he's here, unless somebody else replies.

keith won't see this, but he just proven conclusively that he is too stupid to

sad.

ricky, ag pilots know the danger of a downwind turn, ATPs (stupidly and in the
face of the laws of physics) claim their is no such danger. you, ricky,
dropped your claim to be an ag pilot when you dumbly denied the downwind turn
danger, which absolutely made hash of your prior crop dusting experience.

ricky, also claimed to have risen high enough in construction management to be
able o steal plywood from a worksite to make a dinghy. you also claimed to
have liveaboards for years in Mexico as an adult. I also claimed to a high
ranking Merchant Marine.

All before you turned 35 years old.

You seem to be mixing your delusions, Jax. It's time you had your meds
adjusted again. Or maybe your Speedos are a bit too tight ...

Care to share the posts where you imagine you read those "claims" or are
you just going to show the readers one more time what a mess your poor
muddled brain has become? Show us the posts, Jax. For once in your
pathetic existence, back up one of your claims.

I for one will not hold my breath waiting. You haven't backed up a
single one of your claims since you fouled usenet with your presence.

Poor Jax, are you really so lost or just insanely jealous of those who
do what you can only read about or pretend to be? Silly little poseur,
Jax. Take your meds and get some rest, maybe you can do better tomorrow.

I don't understand what you mean by "overprotected".

I think I know what you are saying about the more noble fittings, which
would be the various through hull fittings.I have seen the wood surrounding
the fittings become deteriorated and spongy to the extent that the plank had
to be replaced.

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

Are you saying that they don't, but should? Or that they don't to avoid the
effects you are talking about?

Ten to 18 years ago I owned a 1956 Stephens, a wooden hull boat. The boat
was in poor condition when I got it and I spent a lot of time in the boat
yard over the 8 years that I owned it. I talked with lots of other wood
boat owners and did a fair amount of research. The general wisdom was that
you DID need to have a zinc anode and all the through hulls bonded to the
boat's electrical system.

If the through hull fitting was completely isolated electrically (such as a
seacock that was only connected via a rubber hose) then there would be no
current flow through it, assuming that the interior wood was dry so that
bilge water couldn't complete a circuit. In this case, that fitting would
be okay. But there are always fittings that you can't isolate, such as the
shaft log, rudder post and strut. These will create a current path,
especially when you connect up to shore power.

If you didn't have a zinc to provide an alternate path, then the current
flowing through the through hull fittings would create an "electrolysis
burn" on the wood. And NO, I am not saying the wood undergoes electrolysis,
I am saying that the effects of adjacent electrolysis damages the wood. Go
to a boatyard that has some wooden boats in it and look at the wood around
the fittings, it will be darker and in many cases severely deteriorated.

When the zincs are mounted you want to space the zinc away from the wood so
that you don't create an electrolysis burn around the zinc.

By the way, I understand that you can create the same situation when using a
Magnesium anode on an aluminum hull. I have heard stories of people who
directly bolted a magnesium anode to the transom of their aluminum boat,
then put the boat in salt water. The resulting "accelerated" galvanic
action with the anode "burned" the aluminum it was in contact with to the
point that an anode sized hole opened up in the transom and the boat sank.
Consider this "hear-say" as I can't confirm it, but I can believe it. It is
best to put bolts through the transom with nuts and washer on the outside,
then mount the anodes on the excess thread length spaced a 1/2" or so from
the hull.
