Diving under the boat to changing the sacrificial zincs.

After 3 successful dives in the Abacos with Dive Guana, we borrowed the equipment and dove under our boat to change the sacrificial zincs.

Choosing a Sacrificial Anode

These days, anodes don’t have to be “zincs.” Sacrificial anodes are now commonly available in aluminum and magnesium in addition to zinc. Often, non-zinc anodes are actually the better choice. Here’s a quick summary, followed by a more in-depth look at this topic:

Zinc works well in saltwater and has been the traditional anode metal for a long time, but it’s also the heaviest option and is more toxic for the environment.

Aluminum is lightweight and works in both salt AND brackish waters. In addition, they may last up to 50% longer in saltwater.

Magnesium is the best anode to use in fresh water, but does not perform as well in salt water.
