Just replaced my Zinc' yesterday. They were still had about 75% left after two years! Boat moored in fresh water and boats in saltwater and or brackish water. What kind of life expectancy should we expect. My last boat moored in salt water and all but three months boated in salt water. Zincs every 6 months. this is my first boat to spend most of its life in fresh water. Both boats are in the 50' range. The Bayliner uses three small isolation transformers, one for each shore power line. It used a 6x12 divers zinc, all through hulls bonded to it, shaft zincs, rudder zincs, and trim tab zincs. The Hatteras uses two very large isolation transformers, shaft zincs and two rudder zincs. Two slightly different approaches, both apparently successful. what say you?
