This is a good read comparing the twist lock to the Smart Plug.

I was on our previous communities harbor committee for 11 or 12 years, and when Smart Plug was first coming to the market they did a presentation for the marina and our committee. It is a great product. During that period we had three or four fires, with one being a major fire. I headed up booming the scene as soon fire was out, which keep the Coast Guard from nationalizing the cleanup, saving the marina and boat owns from really large bills. I got our harbor master to wake the docks with a infrared heat gun looking for over heated shore power connections. I also get him a current clamp meter. If you clamp around the whole marine cable and get a amp reading, then current is returning via the water and not the neutral in the cable, equals hot harbor. Which is not good.
