Corrosion damage to metal parts such as the rudder blade, keel and anchor shaft is not only unsightly, but can also quickly become costly. Fortunately, this damage can be prevented by simple means.

Why corrosion protection is important:

Corrosion caused by constant contact with water weakens metal parts and leads to expensive repairs. Parts under water are particularly affected, as they can rust and fail quickly without protection.

Effective protection through sacrificial anodes:

One of the most effective methods of protecting metal components on the underwater hull from corrosion is the use of sacrificial anodes.
These special anodes are made of a less noble metal than the component to be protected and sacrifice themselves to a certain extent. This process is known as cathodic protection.

Tips for selecting and installing sacrificial anodes Material selection:

Sacrificial anodes are available in various materials such as zinc and aluminum.
The choice of the right material depends on the water environment.
Zinc is well suited for salt water, aluminum for brackish water & fresh water.

Size and quantity:

The anodes should match the size of the component to be protected, our anode calculator will help you to find the right number of anodes. here

Installation location:

The anodes should be mounted at the points that are most exposed to corrosion. Make sure that they have good electrical contact with the metal component and are not insulated by paint or other coatings.

Regular inspection:

Sacrificial anodes wear out over time and must be checked and replaced regularly before they are completely corroded and lose their protection.

Conclusion:

With the right choice and installation of sacrificial anodes, you can effectively prevent corrosion damage and extend the service life of your boat parts.
