Last year, we first told you about the Nautilus, a planned US$25 million superyacht designed by Germany's U-Boat Worx, that's also a submarine. The company has now provided the first images and descriptions of the vessel's interior, which looks like it would do Jules Verne proud.
To update our previous article, the 123 ft (37.5m) Nautilus will serve as both a surface-going yacht and a luxury submarine. Amazingly, it will transition between its two modes on the go, while out at sea.
The vessel will be capable of carrying 10 passengers and seven crew members, with a diesel-electric powertrain delivering a cruising speed of 9 knots (17 km/h) and a range of up to 3,200 nautical miles (5,926 km) when traveling on the surface. Once submerged, it will be able to cruise at one third of the surface rate and dive to a maximum depth of 150m (492 ft) for up to 12 hours at a time, with a range of 100 nautical miles (185 km).
In the central saloon, passengers will be able to socialize and watch movies on a large flat-screen TV with a surround sound system - or better yet, they could peer out at the undersea world through more windows. For really serious fish-viewing, though, guests can head to the panoramic Mezzanine Observation Lounge. Naturally, the dining room and bar also have windows to ensure you never miss a passing manta ray.

As you might expect, the accommodation is equally sumptuous. There's a master cabin with a private ensuite bathroom that has a walk-in closet. There will also be four guest rooms featuring a bed placed directly in front of an underwater window, a wardrobe, plus a bathroom with a shower.
Other interior features include a spiral staircase between levels and a gym. It should be noted that all of the underwater windows will remain submerged even when the vessel is at the surface, so guests can observe the underwater world whatever mode the Nautilus is operating in.
