Bottom line is that the zinc anodes on your vessel and drive may erode
at a much faster rate due to stray current in the water. Zinc is more sac-
rifi cial than many other metals used on boats such as stainless steel.
At the end of the day, you want your underwater metals protected,
and you want your zincs to erode at a predictable rate for ease of
maintenance.
With the galvanic isolator installed as part of your battery charger op-
tion, it effectively isolates your boat from others around you (blocking
any damaging DC fl ow) while still maintaining the integrity of the
shore power safety ground (extension cord plugged into dockside).
The galvanic is the best way to prevent damage to vital metal parts on
your vessel.
