IIRC, Faraday had movies where people could touch the inside of a highly charged cage and not get shocked.

It's the same reason you don't get shocked inside a car -- has nothing to do with the rubber ires insulating.

melodycs30 A fellow sailor told me that during a lightning storm to make sure your engine is on and your prop is turning at a very fast RPMs to expel the static electricity from the boat. Any truth to this?

imagine2frolic capn dave,

Friday was quite a show. I could see from Orange Park all the lightning south. 2 weeks ago I didn't take a direct hit, but it got my SSB, and autopilot. Ruby lost nearly everything electric. This summer has been alive with lightning!.......i2f

That's my lightning stories for now.

I guess the battery kept the bilge pump going for 2 days before it died.

I makes you want to get a bilge alarm that calls your cell phone or something. Our bilge pump switch is hooked to a buzzer that let you KNOW it's on. That only works when you are on board.

Every first hand lighting strike I have read about says the same thing. Much like what was said above, they felt the "charge" before the strike. If you are feeling that tingly feeling that is the time not to be touching anything that can be conductive.

jerryrlitton One of our BlackHawk helicopters took a hit while on the ground. The tail rotor looked like a broom when it was said and done. All the avionics were of course fried. Took a hit while airborne once, all it did was two burn marks where it entered and exited.

zeehag i was sleeping in lost angeles harbor in 1991 and i was on a power boat---a lightning bolt came down across the channel from me at 0308-i had awakened at 0300-i saw the scatter under it as it touched the asphalt---my ex hubby and my cat were asleep together sorta next to me--cat weighed about 20 pounds--was on his stomach---curled up=---the thunder made cat jump--he did so without waking---landed back on hubbies tummy without awakening either of them--i cracked up laffing---that woke cat and he made man awaken--neither knew what happened--was soooo funny....
