Re: Why ground rig to swim ladder?
Sailboat rigging can pick up an electric charge from various sources. As I understand it, electricity exists within an electromagnetic field, and, if a sailboat's rigging passes through that field, it can "collect" some of those radiated electrons. Those electrons try to find a way to go to ground. If you touch the backstay when the rigging is charged with electrons, and simultaneously touch the outboard motor while it's in the water, the electrons will go to ground through you. I used to have to sail under a high power transmission line hanging across the mouth of a broad creek to get to my marina, and got a pronounced electrical "bite" in just that way several times.
