    Re: Lightning at sea - James Cook - Chain
    From: William Sellar

    I cant remember where, but I once read about the history of chain and
    lightning in the British Navy.  The admiralty experimented with chain
    from the mast head to the water for many years.  They used chain only
    because that is what they had.  It created a lot of problems, even while
    it helped channel lightning.  The chain would get corroded and oxidized,
    so that the electrical connection between each link was poor and of high
    resistance.  When lightning did come down a chain it would spark between
    the links and set the masts and sails on fire.  They eventually figured
    it out and replaced the chain with some type of solid conductor.
