I would think that the oars move on their own, in that one pic that PA posted in the begining of this topic Stranger seems to be sitting at the end of the boat in a relaxing and pondering mood while the boat seems to be rowing away.

Another thought I had was that the little Karate guys, as they've been dubbed, put some type of mystical spell on Strangers boat to row when he wants it to. After all in all the pic's I've seen of them they always have strange tatto's and are acting mystical.
