A cathodic protection system is an electronic device designed to eliminate corrosion from a boat lift in sea water. Corrosion is a major problem for boats and boat lifts that are exposed to salt water, as the salt water can cause metal surfaces to corrode and deteriorate over time. A cathodic protection system works by using an electrical current to prevent the corrosion process from occurring. The system consists of two main components: an anode and a cathode. The anode is typically made of a metal that is more reactive than the metal of the boat lift, such as zinc or aluminum. The cathode is the metal surface that needs to be protected, such as the steel or iron of the boat lift. The anode is connected to the cathode by a wire, and an electrical current is passed between the two. As the electrical current flows, the anode corrodes instead of the cathode. This sacrificial corrosion of the anode prevents the cathode from corroding. The system can be adjusted to provide the correct amount of current to prevent corrosion, and can be monitored to ensure that it is functioning properly. Cathodic protection systems are commonly used on boats and boat lifts, as well as on other metal structures that are exposed to salt water, such as oil rigs and pipelines. They are an effective way to prevent corrosion and extend the life of metal structures in harsh marine environments.
