In my link there is a picture of the anode for the 6 gallon Raritan. This one is integrated into the hot water nipple. Nothing remained of the original. They start as 1/2" to 3/4" diameter rods and will typically be as long as can be accommodated by the tank. In this case, about 12". There is an iron core which gives the anode strength and electrical continuity. It is not uncommon to have the core be the only thing left. In my case even the core had rusted away.

If shore power can waste your shaft anodes why not the one in the water heater?
