| CDK, I would guess the coated metal parts develop a blush due to the field caused by the zincs. Calcium may due this if there are temp swings or if the CO2 level changes day to night. Just guessing.  |

| There certainly is a flow of electrons from the zincs to the props and stern tubes. This may change the surface of the anti-fouling paint and provide a better holding ground for the sea creatures. There is a lot of calcium present because this sea has limestone mountains on all sides and most of the deposits are calcium: they can be chemically removed using hydrochloric acid.
