zinc anode

Anodes are inexpensive which means it is important to protect your boat with a quality product.Cathodic protection is an electrochemical process which halts the natural reaction (corrosion) of metals in a particular environment by superimposing an electrochemical cell more powerful than the corrosion cell.

Sacrificial Anodes are fitted or bonded to the metal to be protected which in turn as it has a greater electrical potential than the anode material becomes cathodic and causes the anode to waste instead of itself. The number and size of anodes is determined by the type of material and the surface area being protected.
