The Cruise Sub series evolved from the template of the iconic Super Yacht Sub 3. This range boasts the largest passenger payload in our fleet.

The best dive experience

  • Unparalleled comfort

    The spacious interior of the Cruise Subs gives license to multiple permutations for individual customisation or bespoke configurations that can incorporate a lounge, separable private spheres, and a carbon fibre toilet.

    Effortless control

    An advanced control system provides pilots with fingertip operation of this craft. When at depth, the eco-friendly Vector Weights provide faster and more efficient traversing to smooth the descent/ascent trajectory.

  • Maximal Speed and Manoeuvrability

    The Cruise Sub easily handles demanding underwater conditions due to its streamlining combined with an 8-thruster configuration. This is one of the most powerful models of our fleet ensuring optimal propulsion at all stages of the dive.

    Unrivalled mission-adaptability

    The Cruise Subs are unique amongst manned submersibles with multiple applications and versatility. These subs are only suitable for larger support vessels or shore-based operations. Research missions can be accommodated with every scientific aspect taken care of to cater for all mission challenges.

Anatomy

Double Sphere

The ‘double sphere’ design offers a field of vision for the passengers never before achieved.

Flexible Diving Tanks

Diving tanks provide buoyancy and stability on the surface. U-Boat Worx’s flexible diving tanks are made of rubber-like Hypalon®. When deflated to dive they completely compress, and do not replace their volume with water. This greatly increases underwater performance as there is no additional underwater mass, improving the streamline. Storing the submersible with deflated diving tanks also requires less space.

Revolving Interior

The revolving seating arrangements make it possible to give every passenger the best view during a dive, regardless of the overall direction. The interior rotates within its own acrylic sphere.

Thrusters

Apart from the basic forward, reverse, up and down movements, the submersible can also move laterally. Lateral movement greatly optimises object approach, view, and dive efficiency.

Underwater Lightning

A selection of the latest generation, high intensity lights are available to put the spotlight on centre-stage when the secrets of the deep appear.

Safety Buoy

The red buoy is characteristic for U-Boat Worx submersibles. When released it marks the position of the submarine on the surface. The Dyneema Rope attached measures 1.5 x the operating depth of the submersible, and is strong enough to lift it to the surface.

Features
  • Lithium-ion battery technology

    The latest in Lithium-ion battery technology is used to give our submersibles the ultimate performance, lowest weight, smallest footprint, and best endurance possible. The Lithium-ion battery can be quickly recharged and is maintenance-free.

  • Freeboard Extender

    Freeboard is the height between the hatch and the waterline. The Freeboard Extender is a sliding barrier that increases the distance between the water and the hatch opening. It simultaneously allows for the submarine to be operated in rough conditions and be stored in low-height garage spaces.

  • MANTA Controller

    The MANTA Controller allows for pinpoint precision manoeuvring. The intuitive controls allow for supervised passenger steering, offering passengers an even more exciting experience. The controller allows quick access to intelligent pilot assistance functions such as Auto-heading and Auto-depth.

  • MARLIN Controller

    Developed to make Launch & Recovery effortless and efficient, the MARLIN Controller is a wireless remote to navigate the submarine on the surface. Once the submarine is in the water the controller can be used to navigate it away from the support vessel without a pilot inside. It can also be used to bring the submarine into position above a dive site or for easy passenger transfer.

  • Auto-depth

    With Auto-depth engaged, the submersible will hold steady at its current depth. When applying vertical thrust, the function will automatically disengage and seamlessly respond to the pilot’s commands. This function is part of the Intelligent Pilot Assistance Features.

  • Auto-heading

    When Auto-heading is activated, the submersible will automatically hold its current heading, whether following a course or facing an object of interest. This function is part of the Intelligent Pilot Assistance Features.

  • UIS

    The U-Boat Worx Information System (UIS) gives the pilot direct access to all relevant information on a clear touch-screen display. This PLC-based sensory network ensures the right information is provided at the right time. The UIS makes diving effortless.

  • Omni-directional operation

    Apart from the basic forward, reverse, up and down movements, the submersible can also move laterally. Lateral movement greatly optimises object approach, view, and dive efficiency.

  • Revolving interior

    The revolving seating arrangements make it possible to give every passenger the best view during a dive, regardless of the overall direction. The interior rotates within its own acrylic sphere.

  • Vector Weights

    Time and battery power to reach your mission depth is greatly reduced thanks to the biodegradable Vector Weights. Once the desired depth is reached a Vector Weight can be released to regain the preferred buoyancy of the submersible. To accelerate the ascent, another Vector Weight may be released.

Safety
  • Maximum depth protection

    The MDP feature prevents the pilot from diving deeper than the submarine’s maximum operating depth. In case the submersible should ever find itself too deep, this safety feature will automatically raise the sub until it is once again within its ideal depth limits.

  • Deadman's Switch

    This DMS safety system will automatically resurface the submersible in the unlikely event that the pilot becomes incapable of controlling the submarine. The pilot needs to acknowledge the DMS every 10 minutes, otherwise it will initiate the ascent procedure.

  • Drop Weight

    This weight can be manually released from within the submersible to increase the buoyancy of the submarine and return to the surface.

  • Safety Buoy

    The red buoy is characteristic for U-Boat Worx submersibles. When released it marks the position of the submarine on the surface. The Dyneema Rope attached measures 1.5 x the operating depth of the submersible, and is strong enough to lift it to the surface.

  • Pinger

    A Pinger gives out a pulse that can be received on the surface. With the receiver unit, you can pinpoint the exact position of the submarine when submerged.

  • DNV GL Certification

    Certified by leading classification society, DNV GL, requires each individual submersible to meet stringent and extensive rules and regulations, as well as pass a range of rigorous test and trials from design to final delivery. Overseen by independent surveyors, this is an independent verification of the safety of every U-Boat Worx submersible.
