In February 2017 we installed zinc sacrificial anodes on steel wire to help protect the hull against corrosion. These work because oxidants, which corrode metals, will oxidize the zinc anode rather than the protected metal structure, thus preventing the structure from being corroded.

Every now and again we have to land the anodes to remove loose corrosion and barnacles to ensure they carry on protecting the hull. That was todays job. Somewhat complicated by our water supply being damaged a few months ago, so we have to pump dock water for our pressure washer.

Above are before and after pics of one of our suicide anodes
