I have a new (to me) 1978 Catalina 30, that I plan to have a diver inspect and replace the zincs. Can anyone tell me what zincs I need to have on hand for the diver, other than the 1" shaft zinc. What size, configuration, and location. I will have it hauled out and repainted this winter, but don't want to wait that long for the zincs.
