Maintenance
- At least 2 times a year, check the corrosion on all of the anodes. Change the anode if
necessary (Before it lost 50% of its weight).
- Use the appropriate anodes for the cruising area: fresh water/magnesium anodes ; Sea
water/zinc anodes.
- When the boat is stored at a dry dock, the corrosion protection is not as effective due to
oxidation of the anodes: even the new anodes oxidize the surface. Before returning the boat
into the water, clean the anodes.
Cleaning anodes
- Use sandpaper. Do not use metal brushes or steel tools to clean the boat, it may damage
the galvanic protection.
Replacing the anodes
- The anodes are fastened with screws and nuts. First, remove the screws and nuts that hold
the anode, then clean the contact surface. Press the new anode to obtain a good electrical
contact.
- Never cover the anodes in antifoul.
- During the first few weeks that the boat is in the water, check the anodes and
if necessary replace them: they erode very rapidly during this period.
