Anode – When dissimilar metals are placed in a conductive liquid, like salt water, electrical current is formed. As current flows from one metal to the other small molecules are lifted from the source metal and transmitted to the target metal. This is a very simplistic view of the way items are chrome plated. This removal of material is called "electrolysis". To prevent metal object on your boat such as Motor, shaft, propeller from decaying due to electrolysis, you place a softer metal in the water attached to the metals you want to protect. This softer metal in most cases is Zinc or Magnesium and it corrodes protecting other metals. The term to describe these metals is sacrificial anode.
I hope this works as a starter point for someone to navigate the seas of sailing language. In my next article, being that I am in the process of buying a boat, we will talk about the process of surveying boats. A boat survey is very much like a home inspection and there are a lot of skills you can apply before hiring a surveyor to look at a boat that will give you problems.
