Lightning Protection questions

#8? Ha, Jon, I've seen the inside of an underground vault with the
walls spattered with copper after a 75KA short vaporized copper bus bars
1/2'" thick by 4" wide. That's one hell of lot of #8 wires in parallel.
Imagine what happens with surge that may exceed 200KA?
I go along with others that have suggested that lightning protection for
a plastic boat is probably an exercise in futility.
So I'm guessing based on what I've read here in this thread, that hanging
a length of chain off the bottom of one of the upper shrouds into the
water -as suggested in a book I have called the "Emergency Reference
Manual"- would be one of those suggestions that would give a sailor some
sense of protection, without actually providing any.
