Description
The anodes sacrifice themselves for the benefit of the protected metals.
They must be cleaned and replaced regularly.
Warning, When they are worn beyond 60%, they no longer retain their protective capacity.
For seawater, use either a zinc alloy or an aluminium alloy anode.
At equal intensity, an aluminium anode weighs three times less than a zinc anode, has a higher electronegative potential and pollutes less.
Ideal for protecting aluminium hulls.
For sailing exclusively in freshwater, a magnesium anode should be preferred
