U-Boat Worx’s submersible superyacht can stay underwater for up to four days

Dutch builder U-Boat Worx unveiled the design of a new, 37.5-meter Yacht Submarine, the Nautilus, at the 2022 Monaco Yacht Show last week. The vessel combines the comforts and amenities of a superyacht with the submersible capabilities of a submarine.

The Nautilus features a diesel-electric propulsion system that allows it to cruise across the ocean at speeds of up to 9 knots (16.7 km/h). It is designed to stay underwater for a maximum of four days or six hours when cruising at 4 knots (7.4 km/h).

The 1,250-ton hybrid can carry 10 passengers and up to seven crew members. It has a range of up to 3,200 nautical miles (5,926 km). The submersible superyacht can also dive to 200-meter (650 feet) below the surface.

The luxurious interior features a 50 square meter (538 square feet) dinner and lounge area with four circular windows, each with diameters close to 4 meters. The proposed design for the submarine has a fully equipped galley, one owner’s suite, four staterooms, and sleeping quarters for up to six crew.

When functioning as a boat, the Nautilus offers a massive sundeck equipped with a freshwater pool, a bar, and a luxurious dining table. A newly invented, completely pressure-resistant electrical tender is stowed under the aft deck and stays outside while the Nautilus is diving. This tender, the Aronnax, may also be used for transporting five scuba divers underwater to the intended dive spot.

When not in use, the Nautilus can be docked at any quay that can accommodate its 6.5-meter draft. The Nautilus has a starting price of €25 million. Once ordered, an owner can expect to have their Nautilus delivered within 30 months.
