When to apply Zinc anodes and when the Aluminium Models?
For vessels, which mostly cruise on inland (fresh) waters, we recommend aluminium anodes, since aluminium has a greater differance of potential with other metals than zinc. This is very important, as fresh water provides a hight electrical resistance than salt water. For sailing on salt water or brackish water, we recommend the use of zinc anodes. Aluminium anodes also function well in salt water but are sacrificed at a much higher rate.
