8.3.5 Anodes
General points
- The sacrificial anodes protect the boat's metal components from electrolysis.
- A sacrificial anode is an expendable part, that by eroding (oxydisation), allows the current to
flow. The anodes used are made of a metal that is more readily reductive than the metal they
are protecting.
- On a new boat, all the underwater metallic components try to be at the same electric
potential, which leads to the rapid deterioration of the anodes in the first few weeks in the water.
- You can put several anodes on the hull.
