Redefining underwater travel
Dutch submersible manufacturer U-Boat Worx has unveiled its latest innovation, the all-electric Super Sub, setting a new benchmark in luxury underwater exploration. Designed for adventurers, marine enthusiasts, and eco-conscious travellers, the Super Sub delivers unmatched speed, efficiency, and sophistication beneath the waves.
With underwater travel evolving beyond scientific expeditions to recreational luxury, the Super Sub represents a significant step forward in combining cutting-edge technology with high-end design. As demand grows for unique marine experiences, this submersible is poised to redefine how we explore the oceans.
Fastest submersible in its class
What sets the Super Sub apart from other private submersibles is its exceptional speed. With a top speed of 9 knots (~10 mph), it outruns many conventional subs, offering adrenaline-pumping performance for its passengers. U-Boat Worx has achieved this through a streamlined, droplet-shaped hull and advanced wing configurations that enhance hydrodynamics, ensuring smooth and efficient underwater navigation.

Luxury meets innovation
The Super Sub isn’t just about speed—it’s about creating an unforgettable underwater experience. Its sleek interior accommodates up to three passengers, providing ample comfort and unobstructed panoramic views. Imagine gliding through vibrant coral reefs or watching marine life in its natural habitat, all while enjoying a first-class environment.
“The Super Sub is our response to the growing desire for personal submersibles that are not only functional but also luxurious,” says a U-Boat Worx representative. “This vessel blends cutting-edge technology with a premium user experience.”
Sustainability at its core
In line with global efforts to promote sustainable marine travel, the Super Sub is fully electric, powered by a state-of-the-art propulsion system. This eco-friendly approach minimises its environmental impact, making it a responsible choice for underwater exploration. The company’s commitment to innovation is further highlighted by the submersible’s efficient energy use, reducing operational costs and maintenance requirements.

Designed for safety and performance
Safety is a top priority for U-Boat Worx, and the Super Sub doesn’t compromise. Engineered to operate in wave heights of up to 3.5 metres, it is built to handle challenging marine conditions while keeping passengers secure. With intuitive controls and an intelligent navigation system, the Super Sub ensures a safe and seamless journey beneath the waves.
A milestone for U-Boat Worx
The Super Sub’s recent float-out ceremony at the Chantiers de l’Atlantique shipyard in Saint-Nazaire, France, marked a significant milestone. This step brings the submersible closer to its official launch in November 2025, when it will set sail for its inaugural season from Fort Lauderdale. Offering seven-night itineraries to destinations such as the Bahamas, Mexico, and the Cayman Islands, it promises to be a highlight for adventurers seeking exclusive marine experiences.
In 2026, the Super Sub will debut in Europe, with Mediterranean journeys departing from Barcelona and Athens. These itineraries include overnight stays in Madeira, Portugal, allowing passengers to explore both above and below the water.
The ultimate in personal exploration
U-Boat Worx has reimagined what’s possible with personal submarines, creating a vessel that appeals to seasoned sailors, luxury travellers, and marine enthusiasts alike. From its advanced engineering to its eco-conscious design, the Super Sub represents a new era in underwater exploration.
