I'm wondering what you would do in a sailboat - big water, slow boat, tall aluminum mast. I don't hear much about injuries though. Many years ago three friends of mine were killed on Ocacoke Island in NC, when one pair beached a Hobie with the mast touching a low slung power line. One of the other two on another Hobie was killed trying to help them. The one thing I learned about electricity in engineering school is "don't touch it".
