There is disclosed herein a vertical ship utilizing the buoyancy principles of a submarine. The vertical watercraft is fluid-dynamically streamlined in the direction of travel and has an elongate, pipe-like hull. The elongate, normally vertical hull is provided with ballast means by which the height of a pilot house on the top of the pipe-like hull may thereby be lifted or lowered. Also, the ballast means permit changes in attitude of the hull relative to the gravity vector. The vertical watercraft may be provided with numerous energy recovery means and, as well, may be used as a mining and cargo vessel.
