At the mooring, I put the keel and the rudder up and , I use to fix a free anode tied on the upper part of the keel( above the roof) with a clip. The anode ( special anode for steel not for aluminium) is diving just at the stern. That can protect the stainless steel keel. In the river, there is a lot of electrolysis with the stream. You can do that also for the ram anode can go a more long time.I have made also a long stick with a light and a mirror to inspect this ram anode when the boat is ashore.
