Details on the sub’s interior are still up in the air, with available options aplenty. A combined lounge and galley area will comprise 538 square feet, while a full galley, master stateroom, four additional guest cabins, and crew’s quarters rounds out the interior. When the Nautilus emerges from the deep, guests will be able to use a sundeck with a pool, wetbar, and alfresco dining table. A specially designed, pressure-resistant tender called the Aronnax will come with the sub, and is envisioned as a way to ferry up to five guests to and from favorite diving spots.
