I was just reading that story. There are 2 marinas on that lake. We used to keep a boat in the other marina. Scorpion Bay Marina isn’t too old and it had excellent management at the time we lived in Arizona. Now they are saying that the owners rewired the boat deliberately, maybe, to get around basic safety features and that the problem was not in the dock. One guy jumped in and disappeared and then his brother jumped in. Then a woman, she survived but the brothers did not. Too bad but it can be very dangerous swimming in a marina although we used to do it all the time.
