I once hooked an underwater power cable running from Manchester, MA to Bakers Island in Salem Harbor. I know, it is shown on the chart but the fishing was good. I could pull the anchor up about 10' off the bottom but that was it. I tied a spare lobster bouy to my line and went in search of a diver. Found some guys scuba diving for scallops and gave them $20 to dive down and free my anchor. When they came back up they said you know what - it was hooked on this big black cable like thing. I said Imagine that! So it appears you don't get electrocuted after all.
