Since its release in 2015, the Super Yacht Sub 3 has convinced the owners of 12 megayachts to commission one for themselves. Still fielding inquiries, U-Boat Worx has added features to make underwater maneuvers easier and safer.

The Super Yacht Sub 3, for two passengers and a pilot, can dive to a maximum of 300 meters (984 feet). Among the new features, the company has developed its own, more powerful thruster. U-Boat Worx pledges that pilots will find controlling direction is now smoother and more exact. All the while, the glass-fronted interior remains quiet.

Yet another important upgrade, the Super Yacht Sub 3 has a better USBL system. USBL, a.k.a. ultra-short baseline, is what vessels on the surface use to track undersea craft (divers, too). The new USBL aboard the Super Yacht Sub 3 has two further functions. Specifically, it permits automatically relaying critical information like the lithium-ion battery life and oxygen levels. (U-Boat Worx says the sub has an endurance of 12 hours.) Therefore, the pilot doesn’t need to provide the information. Additionally, the system provides real-time GPS data overlaid with Navionics maps, for more accurate navigation and obstacle avoidance. This is especially key, since the depth to which the Super Yacht Sub 3 can go is the twilight zone. Also called the dysphotic zone, the depth has little light penetration. All of this data appears on the standard touchscreen monitor for the pilot.

Unchanged, though, the sub suits most superyachts’ decks and tender garages. It measures 126 x 96 x 68.5 inches (320 x 244 x 174 centimeters). Put another way, the measurements are 10.5 x 8 x 5.7 feet. A single lifting point makes launching and retrieving easier. Equally important, the company keeps weight in mind, about 8,378 pounds (3,800 kilograms). Furthermore, while comfortable chairs for passengers and the pilot have always been available, the Super Yacht Sub 3 has a more ergonomic-oriented pilot’s seat.

Finally, and also unchanged, the sub has a huge acrylic sphere as its window to the undersea world. Most of the operational systems are toward the stern, therefore providing passengers and the pilot with tremendous views, including down below.
