6.2.3 Anodes for prevention of galvanic corrosion

One of the most important maintenance tasks when owning a boat is making sure you
protect the hull and engine from electrolytic corrosion. This can otherwise quickly
create serious damages. Ockelbo boats are therefore equipped with sacrificial anodes,
made from zinc, which is designed to corrode instead of the boat and the engine. They
are mounted at the bottom recess (see the figure given below).
The anodes must be inspected annually and renewed if more than 50% are wasted. It is
important to inspect the working surface of the sacrificial anode to ensure that it is free
of paint and chalky corrosion deposits and particularly very important on the contact the
surface between the anode and the hull.
Your engine is likely also equipped with anodes that need to be maintained, see the
engine manual for further details.
