Possibly this will help you, or, at least make you feel better. 


Although I cannot provide any reference for this, I was once told that when a bonding system is connected to more than one anode, the anode depletion be unequal between the anodes and the anode closest to the "load" will deplete first. I believe this to be correct and I have what you describe on many Amels.

The only reason that one zinc would not corrode as expected is that it is not making proper electrical contact with the bonding system.  


When you are hauled out, check for continuity between the problem zinc, and the rudder post in the aft cabin. You will likely find that the connection is broken.  


Once you remove the zinc, you might quickly find the problem with the bolt or the zinc.  If the problem is not obvious right there, you'll need to dive deeper into the internal structure of the rudder to find the problem.

Hello AMELians,


I found out that the zink anode on starboard side doesn't corrode. What could be the reason? What I have to check?


The zink anode on portside corrode as expected.



Thanks so much in advance
