This is an informative site about Faraday Cages: http://www.princeton.edu/~achaney/tmve/wiki100k/docs/Faraday_cage.html
We had them at maintenance shops located at TV and radio transmitter sites to enable interference-free equipment testing in high RF environments. Direct lightning strikes on transmission antennas and equipment were always a crap shoot as to what damage would be incurred. All towers, buildings, cages and protective devices were religiously grounded. Some times they would survive direct hits, and, at other times, damage would occur ranging from catastrophic to minor. Always a surprise. Rich Knowles INDIGO LF38 Halifax, NS.

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.
