Demetri's PictureGood writers, no matter their genre, wear the hat of researcher at one point or another in the writing process.

Is there anyone, of any age, who has read Twenty Thousand Leagues Under the Sea and not sketched their vision of the Nautilus in their imagination or down on paper? For 150 years, the submarine created by Jules Verne has captivated readers and inspired countless interpretations.

Jules Verne was meticulous about incorporating the cutting-edge technology of his time and making reasonable extrapolations. The Design and Construction of the Nautilus takes Jules Verne’s in-text descriptions, paired with extensive research on the technology of the time in which Verne’s iconic book was written, and presents detailed construction plans, design notes, and operational theories based on modern submarine technologies.

The Nautilus is more than just a 19th-century mechanical marvel. She has always represented the ultimate technological triumph over nature, a symbol of mankind’s mastery of our domain, and the human desire to explore the unknown.

“The Design and Construction of the Nautilus is the most technically accurate compendium of Nautilus re-imagining I’ve ever seen,” Emily Hitchcock, CEO of Boyle and Dalton, said. “A perfect synthesis of imagination and engineering, this book contains historical references, expert submarine knowledge, blueprints to pore over, and a solid dash of adventurism. A must for any true Verne fan.”
