I've seen it too, and actually, there's a very practical reason for having a set-up like that. It gives you a chance to take a break sometimes for one, but here's another:
One night Ann and I were gettin' up in the seat, and I sat down over on her side. She looked at me and said, "I can't drive this boat!"
I said to her, "OK, girl friend, here's the scenario. We're up on Jullington Creek, there's nobody around, and I think I'm having a heart
attack. You've got to know how to get us home if that happens."
With the stick in the middle either person could practice, or operate in an emergency.
She did pretty damn good ...... I don't let her drive anymore :lol:
