U-Boat Worx has unveiled its latest innovation, the Super Sub, a sleek, ruby-red submersible designed to redefine underwater exploration. With a top speed of 10 knots—three times faster than most personal subs and even surpassing a dolphin’s average speed—the Super Sub promises unmatched agility and precision beneath the waves.

Cutting-Edge Speed and Maneuverability
Sporting a droplet-shaped hull and advanced wing configurations, the Super Sub is engineered for dynamic underwater performance. Capable of steep 45-degree climbs, sharp turns, and lateral movements, it boasts the speed and handling of a supercar compared to the traditional family SUV of personal subs. These advanced features make it ideal for exploring reefs, shipwrecks, or navigating strong currents with ease.
“It’s a first-class ticket to explore the ocean like never before, combining speed, safety, and sophistication in every dive,” says Roy Heijdra, marketing manager at U-Boat Worx.

Designed for Comfort and Innovation
The cockpit of the Super Sub blends comfort and technology seamlessly. Its two front passenger seats, positioned within a large acrylic bubble, provide panoramic views of the underwater world, while the pilot is seated behind. For added security during high-speed dives, the seats are equipped with five-point harnesses.
The submersible’s advanced U-Boat Worx Information System (UIS) delivers real-time navigational data via a touchscreen interface. Key safety features include:
- Maximum Depth Protection, preventing descents beyond the 300-meter (1,000-foot) limit.
- Deadman’s Switch, allowing a passenger to initiate an automatic ascent in case the pilot becomes incapacitated.
- Auto-Heading Mode, akin to autopilot, which keeps the sub on a steady course during extended journeys.

A Visionary Design
With its cylindrical shape, large rear propellers, and hydrofoils, the Super Sub combines aesthetics and performance. Its electric motor, powered by a 62 kWh lithium battery, delivers a total output of 100 kW, ensuring smooth operations while also powering onboard amenities like air-conditioning.
Applications Beyond Leisure
While ideal for personal use, the speed and maneuverability of the Super Sub could make it an invaluable asset for search-and-rescue operations or scientific research missions.
By blending speed, sophistication, and cutting-edge technology, U-Boat Worx’s Super Sub truly stands out as a game-changer in the world of personal submersibles. Whether for adventure, utility, or discovery, it delivers a unique underwater experience that feels straight out of a Bond movie.
