I may have this wrong, but I don't think that wire grounding the mast to the
keel actually can pass a lightning strike. I think it simply drains off any
induced charge built up on the mast, thus lowering the potential for a strike
to the mast. So the probability is still out there.RonWild CheriC&C 30-1STL

Subject: Re: Stus-List Lightning protection by design?
After you have done what has been suggested, you have taken all 'reasonable'
precautions to minimize the chances of serious damage from a strike IMHO.
I don't think it is possible to reduce these chances to zero, no matter what
precautions you take--a strike contains so much energy/second that it could
destroy any bonding before it is over or overwhelm it and thus jump to any
nearby object, metal or plastic, grounded or not. A tree in my back yard took a
direct strike awhile back and did not explode or burn--it just died and had to
be taken down. However, EVERY motor in my nearby house was destroyed by the EMP
produced by the strike-washing machine, dryer, garage door opener, etc.
Seamanship to avoid t-storms, luck and insurance are your last and maybe the
only resorts you have when out in such weather.
