My zincs dont waste away very fast because I have no stray voltage in
my hull. My hull is isolated from all electrical currents bith AC & DC.
I also use a isolater to keep any stray voltage from other vessels of
the dock power from causing any damage. My zincs are 20 pound tear
drops and will last 3 years without 50%loss.

Way more seafood if you can hire someone brave enough to challenge the
N. Atlantic to go and get it for you. Here we go and get it for free.

While your boat dries and and starts to shrink and crack and hogg we
will be sailing the gulf or bays year round.
