Abstract
A lightning protection installation for boats comprising a copper lightning rod mounted on the top of the mast or, in the case of a power boat, mounted on the deck, a copper wire attached to the rod and running downwardly to a point where it is attached to a retractable copper conductor. The copper conductor is retractable through a plastic or fiberglass tube or box molded or inserted in the hull or attached to a centerboard, if available. When the conductor is raised to the passive position, it is protected from the formation of marine growth; and when it is lowered, the conductor provides sufficient wettable electrical conducting grounding surface to conduct the lightning to water ground. Raising the conductor removes the slight drag caused by the grounded conductor.
