摘要： 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.
摘要翻译：一种用于船舶的防雷装置，包括安装在桅杆顶部的铜避雷针，或者在动力船的情况下，安装在甲板上，连接到杆上的铜线并向下延伸到其附接点到可伸缩的铜导体。铜导体可以通过模制或插入船体中的塑料或玻璃纤维管或箱体缩回，或者如果有的话可以连接到中心板上。当导体被提升到被动位置时，它被保护免受海洋生长的形成; 并且当其降低时，导体提供足够的可润湿导电接地表面以将闪电导向水面。提高导体可消除接地导体引起的轻微阻力。
