| Sacrificial anodes | Periodical check (as necessary, according to the floating area) Assembly/disassembly |
Metallic parts are protected against galvanic corrosion (caused by electrolytic currents due to the approach of different metallic bodies as steel or aluminium) by means of sacrificial anodes fitted on bottom hull, on stabilizer, on propeller shaft, etc.. The anodes’ wear may depend on environmental factors as nearby chains, hulls or metallic docks, bad insulation of ground electric systems. |
Periodical check
This operation must be carried out with yacht on dry shore or with the help of a diver.
Have the outer condition of the sacrificial anodes checked and have them replaced if they show evident signs of corrosion or if their volume is reduced to about 50%.
With the yacht out of the water, it is good practice to use a wire brush, to remove the surface layer of oxide and dirt on the external surface of the anodes.
Do not use pressurised water to clean the sacrificial anodes.
To clean and check the yacht in water: disable the engines and generators start.
Check the anodes’ wear conditions very frequently (when the yacht is on a dry shore or with the help of a diver) and replace them as soon as wear exceeds 50%.
Failure to replace the anodes causes corrosion on other metal parts.
Assembly/Disassembly
The sacrificial anodes are fastened to the yacht in several positions of the hull. We advise you to clean the seat of the sacrificial anode and cover with silicon the screws ends which fasten the anodes. This will easy the replacement of the anodes when worn out. We advise not to tighten the nuts fastening the anodes with glues or other materials which will hinder their removal.
Do not cover the contact surface between anode and hull with silicone.
