ANODE RUDDER 70mm UK

Function and technical context

The 70mm rudder anode acts as sacrificial cathodic protection on the vessel's rudder, attracting electrolytic corrosion to itself to preserve the integrity of the rudder's structural metal. It works on the anti-corrosion protection system of the hull and submerged appendages, neutralizing the galvanic currents that are generated when different metals coexist in the marine environment. Its presence is critical in both salt and brackish water environments, where electrolytic corrosion acts rapidly and can compromise the maneuverability of the boat in very few seasons. An exhausted or missing anode leaves the rudder exposed to progressive degradation that can lead to perforation of the metal or seizure of the steering hardware, with the consequent safety risks in navigation. The reference TEN00101UK identifies this component manufactured according to UK standard, widely used in pleasure and work boats with conventional rudders.

When to replace this part?

The clearest indicator that the rudder anode needs to be replaced is a reduction in its mass by approximately 50%, at which point it no longer offers sufficient protection; Visually it appears irregular, very reduced in volume or with cracks. It is recommended to inspect and replace the sacrificial anodes at least once a season, coinciding with the annual beaching, or every time the boat remains for a long time in areas of high electrical conductivity of the water. Replacing the rudder anode preventively before it is completely depleted is the most economical measure to avoid replacing the entire rudder or repairing its structural elements.
