I'm not saying that this is a code requirement anywhere BUT: The only system that I would let anyone I loved around would include a transformer at the boat slip.
Don,
If we go back to my original statement, I wouldn't worry climbing onto that slip my way and wouldn't go near it the code compliant way you mentioned. I would like a specific code reference if you wouldn't mind because I'm more of a theory guy than a code guru. My only hope is that anyone going up or down that ladder now, as built, is in compliance with J3:16. Our poster has already measured a more than lethal current and our code experiment, future victim, has already felt the warning tingle. Alot of folks don't get that many chances or warnings.
