Re: Boy killed by lightning in our anchorage, what would you do?
You are safer warm and dry in a cabin, than having any part of your body touching water.
Even if the lightening strikes the boat, risk of a flashover going through the dry cabin air through your body then back through the hull is (smaller) than induced currents conducting through water, and your wet body.
Resistance of dry skin several Kilo-Ohms, resistance of wet skin a few ohms. Bottom line if lithening strikes within a few hundred yards of the body of water, (lake, etc...), that you are in contact with it will kill you.
If they had gotten into a lightening rod protected building before the strike they would have been safer, but obviously they were too late.
If I had to choose between laying flat on a beach, or a field, or a parking lot, or staying aboard, ... I would throw a heavy guage wire attached to a metal plate and the mast overboard, and go to the V-berth and take a nap.
