U-Boat Worx has unveiled what it says is the deepest-diving tourist submarine on the market.

Especially designed for cruise ships and tourism, the new range comes in three 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 m making them the deepest-diving tourist submersibles ever, it says.

Depending on the model, the submarines can carry 5, 7 or 9 persons per dive.

After the success of submersibles operated from luxury cruise ships like The Taipan from Star Cruises and the Crystal Esprit, the Netherlands-based submersible manufacturer is seeing increased demand from the industry.

“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”.

Traditional tourist submersibles have small windows, and passenger seating much like a bus. The new Cruise Sub series is based on the U-Boat Worx submersibles that are used on exclusive private superyachts and by research institutes. All guests will enjoy the same panoramic experience thanks to two large acrylic spheres that place everyone on the front row.

The interior can revolve inside the sphere, ensuring passengers always have the best view while diving – regardless of the direction the submersible is travelling.

The submersibles are designed to international standards and can be operated non-stop for up to 12 hours. The submersibles are battery-powered and therefore have no impact on the marine environment in which they operate, so diving in a U-Boat Worx submarine is an ecologically sound activity.

The Netherlands-based U-Boat Worx builds the most advanced private submarines, setting the standards for 21st century underwater exploration. They are built in small series at the company’s headquarters in Breda, where hundreds of parts are meticulously put together to provide clients with the safest, most innovative and most luxurious submersibles on the market.
