REC. ANODE BENETEAU 30mm

Function and technical context

This 30 mm replacement anode for Beneteau boats acts as a cathodic protection element, sacrificing itself electrochemically to prevent galvanic corrosion from attacking the structural and propulsion metal parts of the hull. Works on the anti-corrosion protection system of the hull and submerged appendages, including propellers, shafts and other metal surfaces exposed to salt or fresh water. Its correct installation and periodic replacement is essential: when the anode is completely used up, corrosion redirects its destructive action towards high-cost components such as the tail shaft, propeller or the metal hull itself, generating serious structural damage and very expensive repairs.

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 lose protective effectiveness. Obvious signs that the anode is exhausted include its completely eroded appearance, reduced to a minimal core, or the appearance of corrosion pits on adjacent metal surfaces. The professional recommendation is to change the anode preventively at each annual beaching, before launching, to guarantee total protection throughout the sailing season and avoid costly interventions in the workshop or on the high seas.
