    Re: Lightning at sea

    Lisa you're kidding, right?  Captain Cook may have been a great
    adventurer but not a scientist armed with 21st century testing
    information.  That was back in 1768 and they in those days were just
    starting to learn about electricity let alone understand it.  Trust me,
    the chain idea will help some but I wouldn't bet my boat's life on just
    that.  Phil
