Features of the Cruise Sub Series

Image

SAILING IN ALL DIRECTIONS

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. Combined with the revolving seating platform the Cruise Sub offers all guests the best view possible regardless of sailing direction.

Image

THE BEST VIEW FOR EVERYBODY

The exceptional architecture of the Cruise Sub with its two large acrylic spheres offers an incomparable immersive dive experience. All passengers share the same unique, undisturbed and undistorted view in all directions. With other tourist submarines passengers have little space or small windows. The spacious interior inside each acrylic sphere of the Cruise Sub allows for a comfortable dive experience while being surrounded by the deep sea. The passenger seats in each sphere are mounted on a revolving platform that can turn to face any direction in order to experience the best view.

Image

FORWARD AND REVERSE EXPLORATION

Besides the ability to sail while the two acrylic spheres face the subject, these submersibles can also sail forward or in reverse direction. Use all horizontal thrusters while moving forward or in reverse to cruise quickly from dive site to dive site. During the entire dive with a Cruise Sub the seating platform can be turned in any desired position in order to get the best view.

Image

BOARDING POSITION

While boarding the Cruise Sub both seating platforms face the middle, which allows passengers to get to their seats in comfort. Underwater, passengers may choose this position to share their experience and enjoy each other’s company.

Image

EVER-READY

Some may believe that getting a submersible ready to dive is a time-consuming operation. However, Owners of U-Boat Worx submersibles know that their submarines are simple, efficient and easy to launch and recover. Pre-dive preparations are swiftly executed by our effective design, state-of-the-art software and smart checklists that ensure your submersible is ready to dive whenever you are.

EASY BOARDING

The Cruise Sub is highly stable yet deftly manoeuvrable on the surface. These are very important characteristics for easy boarding of the sub. Nobody gets wet feet while embarking or disembarking the Cruise Subs! Ergonomic and strategically placed handrails, grips and steps help explorers young and old to board safely and comfortably.

Image

EFFORTLESS CONTROL

Each U-Boat Worx submersible is delivered with a world-class pilot training course. The intuitive interface of our submersibles is easy for pilots to learn. Unique to the U-Boat Worx private submarines is passengers being able to navigate the submersible while under supervision of the pilot. The unique control device – the MANTA Controller – can simply be handed over by the pilot to his guests for a once-in-a-lifetime opportunity to personally steer a submarine.

Image

LAUNCH AND RECOVERY

When designing each model, U-Boat Worx factors in a variety of specific solutions to ensure safe and effortless launch and recovery from any type of support vessel. The Cruise Sub range is no exception. Its dual lifting point configuration – optionally via a single lifting point – allows for safe and quick launch and recovery.

Another unique feature of each U-Boat Worx submersible is the MARLIN Controller. This wireless remote control allows the operator or pilot to steer the submarine while it is on the surface – effortlessly guiding the sub away from, or back to, the support vessel.

Even with the impressive spacious interior for the large number of passengers, the Cruise Sub has a relatively small footprint. Once the Cruise Sub out the water is, it will demand very little space on the support vessel.

Image

TOURIST OPERATIONS TO GREAT DEPTH

When the Cruise Sub is used for tourism it will offer tourists a once in a lifetime experience. Depending on the model, they can even dive to depths of 1,700 meters. The Cruise Sub series makes it possible to set up a unique tourist operation that will create unforgettable memories.

Revolving interior

Each sphere features a revolving seating platform, which allows passengers to have the best view possible regardless of the direction the submarine is travelling. This design feature allows everyone to enjoy an unencumbered view and first-hand experience of deep exploration diving.

Pressure-Tolerant Battery system

The Pressure-Tolerant Battery System houses the batteries and electronics in oil-filled pressurised enclosures. The use of pressure-resistant components reduces the size and weight of the submersible, particularly on the deep-diving models.

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. The Lithium-ion Battery System can be quickly recharged and is maintenance-free.

MANTA Controller

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

MARLIN Controller

Initially developed to make launch and recovery effortless and safe, the MARLIN Controller is a wireless remote that can navigate the submarine on the surface. Once the submarine is in the water, the controller can be used to steer it away from the support vessel without a pilot inside. The MARLIN Controller can also be used to keep the submarine in position above a dive site, while the pilot assists with passenger embarkation.

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 forms 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 forms 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 touchscreen display. This PLC-based network of sensors 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.

MAXIMUM DEPTH PROTECTION (MDP)

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 certified depth.

DROP WEIGHT

This weight can be manually released from within the submersible to increase the buoyancy of the submarine and return 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 at all times the exact position of the submarine when submerged.

DEADMAN'S SWITCH (DMS)

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

SAFETY BUOY

The Safety Buoy is characteristic for U-Boat Worx submersibles. When released it marks the position of the submarine on the surface. The safety buoy of the deep-diving C-Researcher models also sends a signal to the mother ship. The Dyneema Rope that connects the buoy with the submersible measures 1.5 times the operating depth of the submersible.

DNV GL CERTIFICATION

Certification by the world-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.

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.
