Abstract

The subject-matter of this Specification is substantially the same as that described in Specification 957,469 but the claims are concerned with a cathodic protection system for boats having metallic or wooden hulls, the system comprising an anode, means for supplying direct current thereto, a sensing half-cell having an exposed bronze surface and means for varying the current supplied to the anode in accordance with the signals provided by the sensing half-cell. Specifications 913,895 and 957,467 also are referred to.
