Some random thoughts on lighting strike.
The unpredictablity of lighting strike is an accurate statement. It seems
to hit what it wants to. A well grounded system is a given; in fact, a
must. Lighting strike over open water is statistically rare. Lighting seems
to favor power boats over sailboats (must be the 'cone of protection' thing
that sailboats have.
Power boats usually suffer greater damage than sailboats. Somekind of
'disapator' is better than none.
It almost ALWAYS explodes antennas and blows EVERY circuitbreaker and/or
fuse. On the more obsure side it ALWAYS alters the ships compass; either by
changing the magnetic field around it or by 'gausseing' or 'degausseing'
the compass card and/or corrector magnets. Get it checked.
When lighting strikes a boat all it wants to do is 'get off the boat'. The
voltage will shoot through the boat 'looking' for the escape route and
leave when it finds it. I once saw a boat almost sink because the exit
route was a thru-hull fitting. Deal with both sides of the issue
-prevention and dissappation. It does wierd stuff to a boat.
