Detached Retrievable Outboard System and Apparatus for Sacrificial Anodes.

Abstract

Semi-circuit systems, methods and apparatus for the protection of metallic elements immersed in an electrolytic fluid against electrochemical corrosion. The apparatus preferably comprises four components: a housing component, an anode component, an electrically conductive cord component, and electrical connector component. In preferred handheld examples, the housing component is positively buoyant, featuring impact and water resistant materials, partially encapsulating the anode, thereby protecting nearby structures from impact damage, while shielding the anode component from sunlight, thereby reducing the rate of marine growth thereon.
