NEMO SUBMARINE BY U-BOAT WORX - LIGHTEST IN THE WORLD

The U-Boat Worx NEMO submarine is the lightest manned submersible ever built: the NEMO 1 tips the scales at just 2,100 kg (4,600 lbs) and stands only 1.48 metres tall, while the two-seat NEMO 2 weighs 2,500 kg (5,510 lbs) at 1.55 metres high. Both can be deployed from land, a boat ramp, or a superyacht tender garage without a cradle or davit, making private underwater exploration more accessible than ever before.

Who Is U-Boat Worx?

U-Boat Worx is a Dutch submersible manufacturer that has defined the standards for personal and private submarine engineering since its founding. Every submarine they produce is built to commercial classification and tested to depth before delivery. The NEMO is their smallest, most accessible model, designed for yacht owners and adventure seekers who want to explore the ocean without the complexity of a full-sized research submersible.

Design and Visibility

The NEMO's standout feature is its fully acrylic pressure hull: a transparent sphere that provides a completely unobstructed 360-degree field of view underwater. There is no steel frame obscuring your sightline. When the acrylic sphere is nearly invisible against the water, the sensation of hovering freely in the ocean becomes visceral and immediate. The exterior design, with its octagonal thruster ducts and car-like stern, earned the NEMO a Red Dot Design Award and a "Best of the Best" designation in the Mobility and Transportation category.

Performance and Range

Both NEMO variants can dive to 100 metres (330 feet) and operate at up to 3 knots for up to 8 hours on a full charge. Standard equipment includes air conditioning inside the pressure hull, wireless underwater communications, LED floodlights, and four spotlights. The navigation setup handles currents and precise hovering for photography or observation. DC fast charging significantly reduces surface downtime between dives.
