Key Features of Aluminum Hull Anodes

• Corrosion may be defined as the deterioration of a metal due to a reaction with its environment.
• For corrosion to occur, areas with different electrical potentials must exist on the metal surface.
• An electrical current will flow between water and fittings made of different metals, causing some of them to corrode away.
• On wooden and GRP boats the propeller, shaft, p-bracket and skin fitting are at risk, while on a steel hulled vessel the whole underwater area is vulnerable to costly and potentially dangerous damage.
• Hull anodes are used and designed to prevent corrosion of the entire immersed steel hull area including exposed shafts, brackets, rudders and propellers.
