The Netherlands-based submersible manufacturer, U-Boat Worx , has launched three new luxury submarine models the Cruise Sub 5, Cruise Sub 7 and Cruise Sub 9.

The Cruise Sub 5 and 7 are capable of diving to 1,140 meters making them the deepest-diving tourist submersibles. Depending on the model, it can carry 5, 7 or 9 persons per dive.

“Our operations on cruise ships inspired the development of the Cruise Sub series,” says Bert Houtman, founder and chairman at U-Boat Worx. “Whether the operator focusses on exclusive deep sea exploration in remote destinations or on doing numerous subsea excursions on coral reefs, the Cruise Subs are optimized for maximizing the guest experience.”

The new Cruise Sub series is based on the U-Boat Worx submersibles that are used on exclusive private super yachts and by research institutes.

The submersibles are battery-powered and designed to international standards and can be operated non-stop for up to 12 hours.
