Zincs protect against galvanic corrosion, which is more of a problem in
salt water than fresh.

Also, clean never hurts.

OK, so we got carried away. We were talking about a fiberglass *boat*,
which includes certain metal underwater parts, e.g. propeller,
through-hulls, rudder shaft etc.

You are correct, the zincs don't protect the fiberglass itself. It will
protect the boat.

The biggest danger to the fiberglass parts, other than collision, is
probably UV sunlight. The wax will help protect that. Washing will
remove salt (corrosive) and, properly done, protect the wax.

OK?

Sacrificial Zincs are designed to deliberately corrode protecting the rest
of the yacht.

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.
