Be aware that towboats pushing barges are on the river after dark. On the weekends, they travel late in the evening to avoid as much recreational boat traffic as possible. Know that they are the largest vessel on the river; they have the right of way over small boats (that’s you and me); they have limited maneuverability and visibility; and they create hazardous conditions for the careless boater.
If you decide to venture out on the river after dark, your boat must have running lights of some type and they must be on and visible in all directions. Without lights, the barges can’t see you, nor can anyone else. And if you are running in a very small water craft, the towboat generates a lot of prop wash near the surface that can affect the control of your boat. Be aware, be safe!
