Our marina has a problem at some slips with stray current. Some of the
boats are loosing zincs at a fast rate while others are not. Looking
for some help in trying to resolve this and what kind of equipment
will I need. Thanks. Chuck


I don't know what you expect to do. The marina has to fix it. We had
that problem for two seasons. I got a little testing gizmo that plugs
into a grounded receptacle and lights various LEDs to tell what is
happening.

The ground on one whole dock was open. That was over 100 boats. They
did fix it, but I had to have a diver replace zincs partway threough
the season once.

I normally do not keep my boat at a marina but did once for a couple
weeks. I dove to unfoul my prop and felt weird in the water, found my
zinc had dissappeared in less than a week. While looking at the zinc
with mask and snorkel, felt "tingly", suddenly realized what was
happening and got out of the water very carefully without grounding
myself to anything.
