Like you, I try hard to avoid having shore power cables dip into the water. But that's because I'm paranoid. And, it's just not good nautical practice.
Usually, however, it's not a problem so long as the insulation is intact. Still, I don't like the idea of AC cables in the water. And, I've seen some pretty nasty situations where cables dipping into the water in wintertime were actually frozen into the ice. This could be downright dangerous, as boat movements could very well cause the ice to cut through the insulation.
