The “Super Yacht Sub 3” has already been delivered to a dozen of the world’s most iconic superyachts, U-Boat Worx says. The latest version, equipped with the new thruster, provides higher thrust compared to its predecessor, resulting in smoother, more precise maneuverability, all while maintaining an unprecedented level of silence. This ensures a serene and relaxing diving experience, the company continues.

Additionally, the upgraded version features an enhanced USBL system with two new functions. Firstly, it enables seamless communication between the submersible and the surface by automatically relaying essential readings, such as oxygen levels and battery life. This reduces communication intervals and improves operational efficiency. Secondly, the USBL system serves as a positioning tool, providing real-time GPS information overlaid with Navionics maps. This ensures precise navigation and hazard avoidance, functioning like Google Maps for underwater use.

“The Super Yacht Sub 3 represents the culmination of our relentless pursuit of excellence,” said Roy Heijdra, Marketing Manager of U-Boat Worx. “With its performance, luxurious amenities, and cutting-edge technology, it redefines the possibilities of underwater exploration for superyacht owners.”
