My boat has an inboard diesel so no ability to direct the prop. It does have a bow thruster, but it's only really used at slow speed, usually right at the point of docking and undocking in tight spaces, once you get the boat moving in forward or reverse you don't need it.
I have no idea about container ship sized boats, though I'd imagine a bow thruster of steerable prop might not be practical at that scale.
