Cathodic Over Protection Risks

Cathodic Over Protection Risks What Are The Risks of Cathodic Over Protection? It is very important to protect metal structures in water. The most common are made of Steel, including: Boats, Wind Turbines and Pipes. The most common method is by using Sacrificial...
How to Measure Hull Potential

How to Measure Hull Potential

How to Measure Hull Potential The Hull potential measure in millivolts (mV) is simply the potential difference between the boats hull and a controlled Silver/Silver Chloride reference electrode. Each Hull material will have a different standard potential. If that...

Metal Corrosion and Boats

Metal Corrosion and Boats From the minute your boat enters the water it starts to rot, corrode or rust. This process will continue relentlessly and your Boat Hull, or any metal components under the waterline, will never be in as good a condition again. All you can do...
