The yacht’s skipper made several passes at the fuel dock, attempting to land. He gesticulated commands, and his first mate slumped over the bow rail with a dock line, shaking her head in disgust. The dock-master paced, jabbering into his VHF radio (no doubt calling for reinforcements). Thanks to the miracle of technology known as a joystick, the skipper was able to move ahead, astern and sideways, all effortlessly. The problem was that he couldn’t seem to get the boat and dock in the same place.
