It will matter... if voltage is introduced to the water (from other
boats, bad dock wiring, etc) then it will flow to the fastest way back
to ground... all the grounded metal (boats, etc) around it.

Thanks for the input from everyone. One thing that is puzzling here.
Each slip is a separate home run to a meter. None of the slips are
interconnected. Each is independent. If this is the case leakage from
other bots on the ground shouldn't affect my zincs. We are looking for
a source that is outside the AC connections. At least that is what I
beleive.

There is an excellent article on testing for grounding problems between
shore power and boat at: http://www.yandina.com/electrolysis.htm

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
