Magnesium, you must be in fresh or brackish water. Oops Here it would be Zinc or less dense aluminum on an aluminum boat,  Here it would be zinc on a steel, wood or fiberglass boat, aluminum or magnesium in the brackish waters. Less dense aluminum on an aluminum boat. Many swear on magnesium on aluminum boat's but that would make the boat sacrificial wouldn't it ?
