No, that is most definitely not fortunate. You have a problem and the properly wired and protected new transient docks points it out. As to the extent of the problem we can't know. Maybe will just kill your anodes faster, if in fresh water, could kill a swimmer so that's really not a joke, or it may just lead to a fire on your boat. You need to find someone with the equipment and the knowledge to figure it out.
