DON’T DISS THE ANODES
QI’ve heard people make disparaging comments about anodes, saying that they don’t really work. Do they? JEFFRICE, from the CB website
ATONY REPLIES... Immerse dissimilar metals in an electrolyte (dirty or salt water) and they will form an electrical cell. Depending upon which direction the current flows in that cell, your hull will be eaten away. Attach a more reactive metal (such as a zinc anode) to the hull or propshaft and that metal will be eaten away in preference to something more important. Hence the use of anodes. Yes, they work.
