Monaco Yacht Show: U-Boat Worx reveals underwater superyacht concept Nautilus

By Nina Done 11 October 2022

Dutch builder U-Boat Worx presented their thrilling new 37.5m (123ft) underwater superyacht concept to lucky visitors at the Monaco Yacht Show 2022.

Dubbed Nautilus, the 1,250-ton diesel-electric vessel is a new class of hybrid submarine coupled with superyacht luxury with a range of on-board facilities. Capable of depths of up to 200m, the superyacht submarine will be able to remain underwater for up to 4 days.

With a series of 4-meter wide circular windows for spectacular underwater vistas, the proposed design features 50 sq. m of lounge and dining space, with acommodation comprising a master bedroom and 4 staterooms, plus sleeping quarters for up to 6 crew. This layout can be fully customisable by the client.

With the Nautilus, the yachting market will never be the same again.

Capable of functioning as a yacht, Nautilus will also feature a retractable sundeck when afloat, replete with a pool, bar and dining option, offering guests an alfresco haven in which to relax and socialise while taking in the beautiful water-level views of their surroundings.

As an added bonus, the superyacht sub easily combats seasickness. “If the sea becomes too rough,” says U-Boat Worx Chairman and Founder Bert Houtman, “you simply dive and continue your voyage in comfort. With the Nautilus, the yachting market will never be the same again.”

The yacht submarine will also contain a pressure-resistant electrical tender for transporting up to 5 scuba divers underwater to their intended dive spot. When not in use, this tender can be stowed under the vessel’s aft deck.

Nautilus will have a surface cruise speed of 9 knots, with an underwater speed of 4 knots. At cruise speed, the underwater endurance is 6 hours. Her 6.5-meter draft will also allow her to be docked quayside when not in use.

U-Boat Worx also confirmed an impressive delivery time of within 30 months from the client's initial order.
