Nautilus - homage to Jules Verne

Flag There are very few fictional submarines which have a place in Naval architecture history. The Nautilus, an electric powered submarine conceived in the 1860s by author and visionary Jules Verne stands out. It was a window into the future and possibly an influence on subsequent real world designs. I set about illustrating the Nautilus after being inspired while drawing a detailed cutaway of the interesting spy-submarine USS Halibut for the Covert Shores Book. Additionally I may have been influenced by some recent Verne related illustrations I did for another book project by C.E. Davis (The Lunarnauts 1904)

Jules Verne created the submarine for his classic novel 20,000 Leagues Under the Sea. In it the submarine's troubled captain, Nemo, sets out to take revenge on civilization by ramming and sinking ships. Nemo has sought refuge in the natural environment of the ocean, roaming in the highly sophisticated Nautilus. Since publication the submarine has caught the attention of generations of readers and submariners.

Exact details of the design are sparse but it is consistently described as cigar shaped with pointed ends and 70m long and 8m wide. The forward end is used to ram enemy ships (Verne was writing at exactly the time that 'locomotive torpedoes' were introduced to the world by British engineer Robert Whitehead, but Verne does not reference this development). The submarine is double-hulled for at least part of the way, and driven by a large propeller at the back.

For diving control the Nautilus uses large hydroplanes mounted at the center of buoyancy. It has no rear hydroplanes but does have a rudder. There is no sail as we understand it but a small retractable pilothouse with viewing ports (this was thirty years before periscopes were introduced to submarines) is used for navigation. A second superstructure further aft houses a lamp. The most important characteristic is the large viewing ports located either side of the spacious salon which takes up the full width of the submarine.

Verne also conceived of divers using self-contained breathing apparatus involving compressed air, almost 80 years before it became the reality!

Probable influences on Verne
Jules Verne did not invent submarines, but he did take on board the advances of his time and extrapolated them into the submarines of the (then) future. The 1860s was a time of increased interest and efforts in submarines. In particular the Civil War created a climate for submarine development as the Confederate Navy sought unconventional means to neutralize the dominant Northern fleet. The most famous of these was the H L Hunley submarine but the earlier Pioneer from the same engineers was an even closer fit to Nautilus. It had a tubular hull with conical ends. These subs were small with the propeller driven by hand-cranks but outwardly they resembled the Nautilus and attacked their enemy by ramming (albeit with an explosive 'torpedo'). - Note, Civil War subs are covered in the Covert Shores Book.

The Confederate States also developed cigar-shaped semi-submersible boats which allowed steam propulsion, again attacking by means of a ram-torpedo.

Much larger but less well known was another Confederate submarine designed by a Mr Alstitt. It fatured a steam engine for surface running and had two decks, but very little is known and the design as illustrated below) does not appear very watertight.

Closer to home Verne would ave been aware of the le Plongeur submarine designed by Captain Siméon Bourgeois and launched in 1863. Unlke he Confederate submarines this was propelled by means of compressed air which was stored in large cylinders which took up most of its hull. Although ultimately unsuccessful, a lot of hope was placed in the design. Jules Verne Nautilus submarine le plongeur

Another probable influence was a series of 'cigar ships' built by American shipbuilders Winans from 1859 onwards. Although not submersible,their spindle hulls resembled the description of Nautilus. Their concept was a fully enclosed wave-piecing hull with minimal superstructure. They also boasted various unusual propeller configurations including a central wrap-around propeller and twin props mounted on both ends of the hull. Finding limited interest in America they moved their operations to Europe with one boat being built in Russia ad another in France. And they were all over the press at the time, albeit viewed mostly as a costly folly. Jules Verne Nautilus submarine winans cigar ship

The Nautilus differed from all these submarines in one important aspect; propulsion. Verne envisaged an electrically powered submarine. The means for harnessing electricity was relatively technology and Vernes overcame the problem of charging the batteries by imagining a Sodium-Mercury compound which could be replenished from salt extracted from seawater. This was not scientifically sound, but accepting this workaround to the then seemingly insurmountable problem of battery life, Vernes was projecting the future of electrically powered submarines. The electric motor described was another scientific improbability, using opposing electromagnets like pistons, but again this does not detract from his foresight.

My attempt at the Nautilus
My design for Nautilus stays with the overall description from the book but incorporates several features of my own contrivance. Please forgive the artistic licence. In a nod to real-world submarine design I replaced the retractable pilot house with a fixed structure which would avoid the telescopic interface which I think would leak. I also shifted the hydroplanes further forward to directly below the pilot house to simplify control mechanisms and mounted them lower on the hull so that the axle passes below floor level. Further aft I kept the problematic sodium-mercury batteries and electromagnetic motor but opted for twin screws (propellers) to allow a fanciful fish-like rudder arrangement.

Trivia
The popular image of the Nautilus submarine is actually the creation of Disney for the 1954 film 20,000 Leagues Under the Sea. It is an interesting design but quite different from Verne's description. More recently, Herve Jaubert, a French-born submarine designer built a private sub of similar appearance for wealthy clients. What connects that to this site is that Jaubert is also an SDV maker although some of his designs are still secret (again, a Covert Shores Covert Shores Book plug!).
