U-Boat Worx Nemo Submarine
Available in both single- and two-seat models, the Nemo from U-Boat Worx is the only series-produced submarine in the world. The Red Dot Award-winning design adopts the company's signature acrylic viewport for enjoying underwater vistas, with a depth rating of 330 feet and a battery-powered electrical propulsion system that can hit speeds of 3 knots underwater. Both models are surprisingly compact, capable of deployment on land, from a yacht, or from a boat ramp, and the single-seat Nemo 1 holds the distinction of being the lightest manned submersible ever built.
