Anodes are attached to your boat to prevent corrosion between two submerged metal surfaces. A boat anode acts as a kind of lightning rod. Corrosion occurs in the least noble metal, the anode, so that the precious metal of, for example, the boat hull, propeller shaft or propeller remains free of corrosion.

Which anode do you need?

There are anodes made of zinc, aluminium and magnesium, large and smaller anodes. So first you have to choose the right anode for your situation, taking into account a number of things: water type, attachment surface and the way of attaching it.

Salt, fresh or brackish water?

You make a choice between zinc, aluminium or magnesium based on the type of water you sail in or where your boat is most often found. In fresh water you use a magnesium anode, in salt water a zinc anode and for fresh and brackish water you choose aluminium.

What type of anode for your boat?

Depending on the location and the mounting method of the anodes, choose which option is best for you. We have anodes that can be welded or screwed and for all kinds of applications: from hull to propeller shaft.

When do you replace a boot anode?

Anodes should be replaced every 1 to 2 years, as soon as corrosion has eaten away most of the anode.
