Rudder anode question
A sacrificial zinc anode must be in contact with the seawater to be effective.
A single zinc anode, of the appropriate size, will protect all immersed metals that are electrically connected (bonded) to it.
Rudder shafts often have a poor electrical connection to the boats bonding system, due to high resistance through the rudder bearing.
