Sir Henry Bessemer was a British inventor who got seasick when he crossed the English Channel in 1868. Inventors are primarily problem-solvers, so Bessemer went to work trying to design a ship to accommodate those who suffered seasickness. What he came up with was the design you see above, in which a section of the ship could move to keep those inside level as the ship itself bounced about in the water. Right away, you can see that the saloon section could only move so far when the ship rolls. You also have to wonder how it would deal with the ship's pitch upward or downward. Yaw probably doesn't have that much to do with seasickness. But the real problem was that it did not depend on gravity or gyroscopes to right itself. It had to be moved manually by an operator working the machinery!
But that's not what doomed the SS Bessemer. The ship was apparently hard to control, and only had one public voyage. Read about the short life of the SS Bessemer and its grand swinging saloon at Amusing Planet.
