sailing in a thunderstorm
Like Jeff and common sense suggest, it is safer not to be out in a thunderstorm. If you''re unsure whether your mast is grounded, it might be a good idea to make sure that it is, and done properly. I have heard stories about masts grounded to through-hull fittings, so that when the lightning hits, it blows the fittings out and the boat sinks. Lightning can do wierd things like that; I believe the fittings blew out because the water in them was instantaneously turned to steam, and the fittings or the hoses simply couldn''t take he pressure and heat. Another fun item I read about is how, when your electronic equipment is properly installed, you put a loop in the wire to nullify charges so as to get less interference. Apparently when a million volts comes down the mast and hits the loops, they become like magneto coils, boosting the amperage (?? I''m not a electrician - it boosts something) that fries stuff even more than it would have in the first place. The best idea is to not get hit, and the next best is to be prepared for when you are.
