REC. ANODE BENETEAU 35mm

Function and technical context

This 35 mm replacement anode for Beneteau is part of the boat's cathodic protection system, acting as a sacrificial electrode to preserve the metal surfaces of the hull, shafts, propellers and other submerged elements against galvanic corrosion. Being manufactured as a specific replacement part for Beneteau boats, it guarantees a precise fit in the fixing points provided by the manufacturer, ensuring optimal electrical contact with the metal structure it protects. Without effective cathodic protection, electrolytic corrosion can rapidly deteriorate submerged metal components, leading to costly repairs to the hull, horn or tailshaft. The reference CMAM235 identifies this anode as a component with a dimension of 35 mm, suitable for the corresponding anchoring points on the Beneteau models for which it is designed.

When to replace this part?

Anodes should be inspected at least once a season and replaced when they have lost between 50% and 60% of their mass, since below that threshold they no longer offer effective cathodic protection. The most common symptoms of an exhausted or missing anode are the appearance of pits or orange spots on the shaft, propeller or metal keel, as well as accelerated deterioration of the antifouling in areas close to the submerged metal elements. It is recommended to replace the anode preventively at each annual grounding, regardless of its apparent condition, to avoid irreversible damage due to galvanic corrosion during the navigation season.
