THE FLIP SHIP
The FLIP Research Vessel (FLoating Instrument Platform) is the only ship in the world with the ability to flip from a horizontal to vertical position while at sea (at least on purpose). Built to study wave height, acoustical signals, water temperature, and density, the ship is 108 meters long and weighs 700 tons.
Although it looks like a normal ship while is it en route to a location, upon arriving the front of the ship is flooded with water causing the back end to go horizontal. The procedure takes about 30 minutes, during which the crew must literally walk up the wall to remain standing. The ship contains a galley, crew quarters, and even bathrooms that work in both positions.
Even in the stormiest seas, the Flip Ship is stable due to the majority of its mass being under the troubled water. The portion that remains above is the height of a five story building.
