    Once did extensive (for me) downloads on everything lightning I could find.
    And I remember Prof Thomson's paper is in a thick file in a box here in the kitchen.
    Altho I will have to read it again to remember anything!

    My impression is that there is no route you can direct a strike to. If it wants
    to come down the mast and jump sideways, it will. If lightning chooses any
    or all at once of the stays & shrouds it will....... My conclusion,
    remember, I really know nada about electricity, domestic or heavenly, is to
    attach heavy duty battery cables to the wire at the forestay, backstay, and
    top shrouds and throw the ends with wired-on chunks of zinc into the water.
    Whatzat, baiting the lightning god?

    I will go below if I can. If I can't, I'll pray that the Faraday tent works the way
    you guys say it's supposed to. I will not ground the mast thru the interior
    of the cabin. Last I heard, we ground to scintered bronze plate because it has
    a lot of surface area in its structure. But somebody else says, wrong, it has to be
    of lot of square footage of solid bronze to guanantee enough mass for a ground.
    I have an objection to fastening a great hunk of metal on the boat underwater,
    because I've also heard that a lightning strike can blow out a big hole....
    right where the ground plate was.

    If I remember, I'll wrap any loose electronics in an aluminuzed survival blanket.
    And throw the breakers on the built in stuff. Make a cup of tea.

    Really have misgivings about grounding the boat thru the interior.
