The way I see it is , it's a smoke screen to rid the lake of a certain type of boat and nothing more. If these proponents were SO concerned with safety the would have a "headway" speed limit for nights. I've been out at night (without a moon) when you couldn't see diddley squat past the bow light and 25 mph would be rediculous. I see their misguided logic as an end run around the fact that they simply can't post signs at all boat ramps...
NO PERFORMANCE BOATS
Correct me if I'm wrong
