I agree. It would likely make it worse. BTW - trivia fact for you all - the most common mode of lightning damage I worked on was a lightning hit on another boat or power pole that came up the shore power cord.

If you get hit by lightning, every electronic gadget you have on board will be fried even if it is not plugged into anything. Thus you will want old fashion alternatives including a sextant if you are offshore. One way to save a hand held GPS would be to put it in a screened cage, known as a Faraday cage, to protect it from the electric field which results from a lightning strike.
