Hi Jan,
I have changed the ram anode last year. I had to file the anode to find the place to put the bottom ram bolt. This year i have a look on this anode with a long stick with a mirror and a little light at the end when the boat is keel down under the crane. I could send a photo of this instrument. Now when my boat is at the mooring in the River Trieux,I put the keel up with a removable anode which is taken by a clip on the top of the keel above the roof. The anode is at the stern in the water with a long iron wire rope. I have seen some electrolisis spot on the keel. So I hope the removable anode could protect more the keel than the only ram anode. Do you another owners making the same system?
Best regards
