If you find yourself in this scenario out of the boat and standing on the ground, it is an excellent idea to stand on one leg or at least keep your feet close together (senator Larry Craig could have benefited from that advice). Sounds crazy, but there is actually some good fundamental science behind it. The flow of electricity is all about difference in potential. It flows from an area of higher potential to an area of lower potential. If there is an electrical strike in the area where you happen to be standing, there will be current running through the ground. If you are standing on one leg, there is no complete path for the current to run through. The wider your stance, the greater the potential difference, therefore the greater the chances of having something extremely unpleasant, even deadly, happen.
