You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

However, in the overall scheme of things, jumper cables are far more likely to cause sideflashes or do nothing than to actually reduce the risk of getting hit. That's been pretty well proven by what studies are out there. You might want to take your own advice and not post a technique, which at best is going to give a person a false sense of security and possibly prevent them from taking effective measures.
From what I have found out. The use of jumper cables or chain is not to direct the lightning hit but to bleed off the static built up in the vessel, thus making the vessel less attractive to the lightning.

Simon, there's two issues at stake here:
a) before the hit, and
b) after the hit.

Sure, jumper cables "might" bleed off static beforehand, but if you get hit they'll be toast... just like this thread should be given that it's approaching 3 months of age...
