I’m confused by that boat. It can be rowed facing the bow, as the guy is doing, although you get better thrust on the oars facing the stern. But that’s not the confusing part. That seems to be a sail attached to the bow. What else is it attached to? A mast somewhere near the stern? Not the usual place for a single mast. The helicopter hovering above, both blowing on and securing the sail? Am I missing something obvious?
