The perspective of this screenshot is completely off. It looks as though his ship is leaning over, and the sail was installed diagonally. How is he standing so vertically on a tilted deck?
He leans to the other side otherwise the ship would capsize ...
No, you're right. The perspective is wrong but it has a good reason: I don't care about it. In exchange some parts of the picture are animated. Great, isn't it? ;)
