Zincs

Caring for a schooner takes way more than ever meets the eye. Schooners are built from wood (oak primarily in the case of Mary Day) and steel (or iron). Mary Day has an 80′ long cast iron ballast keel bolted to the bottom of the wood keel with very large galvanized bolts. In the salt water environment these steel and iron bits get “eaten” up by what amounts to minute electrical currents created in a number of different ways. Preventing that “galvanic action” requires sacrificing “softer” kinds of metal to protect the keel and the keel fastenings. Zinc is a tried and true kind of metal that unselfishly sacrifices itself. Every year we bolt zincs onto the ballast keel and every year we have to renew them as they slowly get eaten away. Zincs aren’t cheap but then again neither are keel bolts.
