i am curious what you do for lightning protection to keep your boat's
electronics from getting zapped in the middle of the big ocean. i
know you can install lightning protection into the boat, that is,
basically a lightning rod and ground plate, etc, but that wasn't
really what i was wondering. what i am curious about is do you have
some kind of procedures you go through when a storm approaches that
has a lot of crackle in it, some procedures for disconnecting
sensitive electronics or somehow disengaging them from the boat's
electrical system so that they won't suffer if the boat gets hit ? i
guess that might be non-sense since stormy times are exactly when you
most rely on a lot of those electronics but i thought i would ask. i
was just curious.

During the recent (worst on record) electrical storm over West Scotland I
felt secure as my TV's are all cable, my PC was switched off, and I was able
to relax, thinking about my poor old neighbours who had Sky and terrestial
TV.

One tremendous explosive flash put paid to that. It zapped my cable modem
completely. This was the only item I had failed to disconnect. Just shows.
Several million volts hitting the ground will even affect underground
cabling enough to zap a device connected to that cabling.
