Description: Fiction's first fully-realized submarine, The Nautilus is a spindle-shaped submersible 70 meters long and 8 meters thick at the widest point. Made of riveted steel plates, it mounts a long ram with a triangular cross-section on the front, and a six-meter diameter screw on the back. Steering vanes (like ailerons on a plane) stud the rear half of the vessel. The pilot house and external lights of The Nautilus can be caused to sit flush with the surface of the submarine, allowing it to achieve 50 miles per hour at its highest speed.

The front half of the lower level of The Nautilus contains an air reservoir, a small chamber (which became Dr. Arronax's quarters, the Captain's stateroom, a huge parlor, a library of 20,000 books, and a formal dining room). At the center, a shaft with a ladder leads to the upper deck, which contains the retractable pilot house at the fore end. Also at this point is the access hatch for the Captain's dinghy, which can be entered while the ship is underwater - the dinghy is shipped watertight, though it is incapable of operating underwater itself.

The rear half of the lower level of The Nautilus is less well described. It contains the airlock, the crew's mess (which doubled as a cell for the three castaways), at least one bunkroom for the crew, another bunkroom which was used by Ned Land and Conseil, and an engine compartment which contained the generator and batteries in the front half and the machinery for the screw in the back half. It is likely that the upper level of the back half of the ship contains an access way to service the powerful retractable lamp. It is also in a side chamber near the airlock that the diving suits are stored.

Captain Nemo brags that the submarine draws power from the sea itself. Although the exact method of electrical generation is not described, it would seem from some portions of the book to use sodium. Since sodium can be extracted (in minute proportions) from seawater, yet reacts violently with water to emit extreme heat, Verne might have been on to something there. The electricity the generators develop is stored in large Bunsen cells, and from there goes to power everything aboard the vessel. Aside from the air-guns, everything aboard ship is powered by electricity, a first in the 1800s.

The Captain's dinghy (which communicates with the sub via a wire that it plays out behind it) is likely large enough to hold the entire crew. At one point Ned Land takes it for a whale hunt, at which point it comfortably housed at least eight people.

The Nautilus is crewed by twenty men of uncertain nationality, who have severed all ties with Mankind, much like their Captain. Aboard ship, they speak only Nemo's created language ("Nautilan") and are extraordinarily quiet and robot-like.

The Nautilus contains enough air for the crew for a day - two days at most, with deleterious effects on the crew's health. Every day, therefore, The Nautilus must surface and open vents to release the built-up carbon dioxide and refresh its air reservoir. Although there were methods known at the time to scrub carbon dioxide from the atmosphere, Nemo doesn't use them, possibly because he still doesn't know how to create the oxygen the crew needs. Nevertheless, this only becomes an issue at one point in the story, so I decided it seemed like more of a plot point than a limitation. Aside from this limitation, The Nautilus seems to have a significant range - Nemo mentions a depth of eight to ten miles at one point, and it's possible he's gone much lower.
