Since its inception in 2005, Dutch outfit U-Boat Worx has unequivocally been one of, if not the single biggest innovator and market leader in the private and recreational submersibles market. Despite the fact the Breda-based brand already offers some 20 different models — including the lightest personal sub, the fastest submersible on the market, and a submarine capable of accommodating up to 120 passengers, all of which debuted in the last year alone — it’s now unveiled what’s almost certainly its most noteworthy release to date with what’s been christened the Nautilus — a 123’ superyacht-submersible hybrid vessel capable of cruising atop the waves or diving deep below them.
Configurable with a variety of custom layouts, the Nautilus has been outfitted with a 215-square foot galley and a 538 square foot dinner and lounge area lined with massive circular windows, plus four bathrooms, four staterooms, and a master suite — enough space to comfortably accommodate up to ten passengers along with seven crew members. When operating above the water, passengers on the Nautilus can bask in the sun while topside on its enormous 635-square-foot upper deck which includes a freshwater pool, a bar, and a luxurious al fresco dining table area. A solar panel-equipped upper deck roof provides shade while atop the waves and folds down to protect the bar area when diving while an elevator also transports passengers from the upper to lower floors.
Constructed around a custom-designed steel hull, the Nautilus also boasts a 25.26’ beam, a 21.3’ draft, and stands at 23’ tall. The submersible superyacht is propelled by a diesel-electric powertrain that affords an underwater speed of 4 knots and a cruising speed of 9 knots. Able to remain below the waves for up to four days at a time, this hybrid vessel also features a depth rating of 656’ and a range of 3,200 nautical miles. The ship also comes loaded with what U-Boat Worx has dubbed the Aronnax — a deployable, completely pressure-resistant electrical tender boat that integrates into the Nautilus’ aft deck when not in use.
Available for order now with a 30-month build time, the U-Boat Worx Nautilus Yacht Submarine carries a starting price of €25,000,000 (~ $24,490,000).
