A summary is made of information known about cathodic protection of ship hulls and related parts. Problems involved in the cathodic protection of hulls are outlined and factors which influence protective current requirements are given. Data reported include protective potentials of steel hulls measured against four reference electrodes, advantages and disadvantages of the sacrificial anode vs the impressed current anode, and properties of magnesium, zinc and aluminum galvanic anodes. 5.2.1
