Sorry for the cornfusion, ALL. Thanks, Brent.
I do remember reading an article by a gentleman who went on to widely publicize the tragic loss of his son to electric shock drowning and to establish a marine electrical business of some sort. He said right after the event he simply stuck one of the probes of his DMM into the water by the boat nearest to the point of the drowning and found significant voltage. I think the article also showed a photo of a bare AC circuit wire touching an engine mount on that boat. So apparently no special equipment is needed to find this paralyzing voltage.
Oh, and as Brent says, the cell I mentioned is a handy dude to have to the purpose he stated.

You get a silver/silver chloride cell like this https://boatzincs.com/corrosion-reference-electrode-specs.html and connect it to your DMM. One side to ground and the cell in the water. Even 10 milliamps can paralyze you and cause drowning.
Sorry Rich, but the you’re confusing tests. The reference cell you’re talking about tests for the potential for galvanic corrosion, not AC current leakage. Just FYI.
