Sacrificial Anodes and Galvanic Protection
Depending on which model and options you have selected your boat may be
equipped with sacrificial anodes and a galvanic protection device.
A galvanic isolator is present on all models equipped with a minimum 30A shore
power system, and is installed just after the vessel’s shore power connection. Signals
can pass through this galvanically isolated circuit, but stray currents, such as
differences in ground potential or currents induced by AC and DC power are blocked.
Sacrificial anodes on your vessel are part of your cathodic protection system. The
anode is made from a metal alloy with a more "active" voltage than the surrounding
metal it is protecting. The difference in potential between these two metals means
that the sacrificial anode material corrodes in preference to the surrounding area it is
protecting.
Anodes do require maintenance to keep them at their peak effectiveness. Repeated
cleanings throughout the season with a wire brush may be required to remove any
buildup that may form.
The anodes on your vessel should be inspected and cleaned every two months. You
should change your anodes after it has corroded to half its original size or when
you’ve accumulated twelve months of immersion in saltwater. When anodes are
cleaned or replaced, it must also be verified that they have good continuity with the
hull. This is an easy step by using a multi-meter set to the ohms scale.
