I have one for you: my bronze sink thru-hull (for the head, which is forward of the mast) was green and partially disintegrated when I pulled the boat this year. The zinc on the shaft to protect the propeller was fine. Thoughts?
Also, I just got my hard copy of the scam letter for USCG documentation renewal. I was almost fooled, and I am aware of the scam. These guys should be arrested for fraud.

I decided to do nothing specific and see if it happened again this last season. I can report that the anodes were in good shape when the boat was pulled last November- much the same as in previous years. So I am going with the shore power stray current suggestion, as I cruised to some new sites last year and spent a few days plugged into shore power in a place I have not been before or since. So if that is correct, Joe Della Barba would be the winner. Maybe we should keep score in the future? Perhaps have a Stump the Chumps episode periodically ala Car Talk?

I have had this configuration in past years and every other year at the end of the season I could barely justify replacing them because there was so little metal decay. I know of nothing I did differently this year. I am on a mooring so rarely plugged into shore power. What would cause a dramatic increase in zinc decay? Thanks and Happy Holidays to all!
