If you own a boat at a Marina - Boat Slip - Please Read....

If it fucks, flies, or floats you're better off renting it.

Make sure that the panel is equipped with 'Ground Fault' breakers/interrupters...

Problem solved...

Our docks are new.. and they each have individual boxes and cut off switches...

I am more concerned that so many OLDER electric cords are in the water.

There are some really old sale boats... with dangling older cords. I could imagine a break in those cords?? I would think it could send electric out into the water??

Stray current at Marinas is common. Electrocution is not.

An undetected AC ground fault which produces a water path current in salt water may not create enough current density to affect a swimmer, even with a defective grounding conductor.

Because of the much higher resistance of fresh water (about 70 times more than salt water), the swimmer can become the fault path conductor when the boat or dock ground is missing. A voltage rise will occur on the underwater gear of the affected boat and cause a paralyzing low level current to flow in the swimmer.

We better outlaw all boats with shore power connectivity.

I believe the phrase goes like this...

"If it drives, flies, floats or fucks...rent it"

But Yes...you're right!

wow never knew this
