Nautilus (Verne) from seawater) is the craft's primary power source for propulsion and other services. "Nautilus" is double-hulled, and is further separated into water-tight compartments. Its top speed is . Its displacement is submerged. In Captain Nemo's own words: "Nautilus" uses floodable tanks in order to adjust buoyancy and so control its depth. The pumps that evacuate these tanks of water are so powerful that they produce large jets of water when the vessel emerges rapidly from the surface of the water. This leads many early observers of "Nautilus" to believe that the vessel is some species of whale, or perhaps a
Jules Verne (crater) crater feature on the far side to be flooded with lava, as the crust is generally thicker than on the near side. The crater is located in outer rim of the South Pole-Aitken basin. The outer rim of Jules Verne is worn and eroded, with several craters lying across the edge. Along the eastern edge lies Jules Verne G, while Jules Verne C penetrates the northeastern rim and Jules Verne Z cuts across the northern rim. A small crater also lies across the southern rim, while Jules Verne P is attached to the exterior along the south-southwest. Jules Verne is
