Why U-Boat Worx Submarines

U-Boat Worx submarines are without peer in every aspect of underwater exploration. Since its inception, U-Boat Worx has defined the standards to create exceptional submersibles. Each submarine is handcrafted and overseen by our in-house experts to ensure every detail is perfect. It was the dream of our founder to create submersibles that offer the best dive experience, a dream that has come true and continues to deliver excellence.

Diving in a submarine is akin to entering another world. When going through the process of selecting the best possible craft for this “space travel”, the relevant characteristics you need to take into account cannot be easily referenced to the selection process of yachts, aircraft, or anything else for that matter.

Step into our world and understand which 10 submersible essentials define the best submersibles in the world; the U-Boat Worx submersibles.

01 UNPARALLELED COMFORT

Each U-Boat Worx submarine is designed to provide unmatched comfort, space and style. All of our submarines have maximum legroom and headroom while keeping overall weight and size to a minimum. This combination delivers the ultimate diving experience.

Efficient air conditioning and surround sound music form part of the fine detailing, together with the optimum ergo dynamics to facilitate ease of boarding and disembarking. In keeping with the ultra-high standards found in superyachts, our submersibles boast the most luxurious of fit-outs crafted by legendary Dutch workmanship.

01

02 CLEAREST VIEW

From inside the U-Boat Worx submersibles, everyone enjoys an uninterrupted view thanks to the strategic placement of all components and the use of an ultra-clear acrylic hull, expertly engineered to make you feel “at one” with the ocean.

In deep and dark waters, state of the art LED lights illuminate the secrets of the surrounding environment.

02

03 TOTAL SAFETY

At U-Boat Worx every submarine is built with safety as the primary consideration, and our reputation for reliability has been established by always adhering to our meticulous “safety first” regime. Designed, built and rigorously tested to the highest standards, the submersibles are all certified by leading classification organisation, DNV GL.

Multiple safety features are incorporated and integrated into the designs at every stage. For example, all U-Boat Worx submarines automatically resurface in the unlikely event of a power outage.

To assure complete safety, in-house experts at U-Boat Worx have developed unique features while our safety testing programmes ensure that each and every component is faultlessly reliable. Each submarine’s hull is individually pressurised to a test depth that greatly exceeds the pressure experienced at its certified maximum operating depth.

03

04 EFFORTLESS CONTROL

The controls of our submersibles are designed for ease of management with the standard UIS (U-Boat Worx Information System). The UIS displays all pertinent information to the pilot via a large touchscreen monitor.

An acknowledged feature of the U-Boat Worx submarines is the MANTA Controller that allows the passengers to navigate the craft under pilot supervision.

The precise and responsive manoeuvrability of the submarine never ceases to thrill the first-time diver, as the craft glides through the ocean’s three-dimensional environment taking in the shipwrecks, coral reefs and other spectacular underwater sights.

04

05 UNRIVALLED MISSION ADAPTABILITY

As mission plans may change over time, the submersible can be adapted to accommodate your requirements. Our engineers have invested a great deal of thought and time ensuring that our submersibles can be equipped with mission-appropriate tools.

The combination of ample payload, modular design and forward-looking engineering allow for many interchangeable permutations.

Some of the optional extras developed exclusively for U-Boat Worx include fly-out ROVs, ocean floor sampling, various fish collection tools, and 4K video recording systems.

06 EVER-READY

Time is precious when organising submersible missions. Pre-dive preparations are easily and quickly executed by effective design and efficient checklists that minimise launch times.

On completion of a diving day, all that is required is a fresh water wash-down, a recharge of the batteries and a refill of the air cylinders to get the submarine ready for the next mission.

06

07 CAREFREE LAUNCH AND RECOVERY

The launch and recovery of a submersible is one of the most critical moments of the operation. U- Boat Worx has perfected the technique for seamless launch and recovery.

Most of our submarines integrate a single lifting point. While most submarines are launched without passengers, there is an option for fully certified launching with the crew and passengers aboard. Flexible lifting arrangements allow for simple integration into a yacht garage.

Another unique feature is the MARLIN Controller, which further simplifies the launch and recovery phase by remotely controlling the submarine while it is on the surface.

07

08 MAXIMUM MANOEUVRABILITY AND SPEED

Complete flexibility and omni-directional movement are the hallmarks of U-Boat Worx submersibles.

Intelligently designed thruster configurations optimise manoeuvrability with maximum capability being achieved from four, six or eight thruster settings.

Advanced Computational Fluid Dynamics are used to streamline the hull to maximise the efficiency and decrease drag giving the appropriate power settings to counteract all conditions of tide and current.

08

09 SUPERIOR ENDURANCE

U-Boat Worx submarines are designed with a full diving day capability. The high-capacity battery systems permit up to 18 hours operation on some models. Our use of the latest generation Lithium-ion technology enables the submarines to be recharged in 4-6 hours either aboard any support vessel or in the water.

Each submersible’s endurance is ensured by abundant Oxygen capacity and large Carbon Dioxide filters. Quick exchange mechanisms form part of the design of the Oxygen cylinders, and Carbon Dioxide filters facilitate non-stop diving.

U-Boat Worx submersibles can perform a minimum of 8 dives per day without refilling, and some models can do up to 12 dives without refilling.

09

10 UNCOMPROMISED SURFACE CAPABILITIES

U-Boat Worx submarines have been carefully designed to ensure total stability while at the surface. Its decks provide easy and safe access for the passengers. Ergonomically designed handles and supports make the boarding procedures of U-Boat Worx submersibles very efficient.

Each submersible can also be towed at speed or travel under its own power on the surface. Irrespective of sea conditions, U-Boat Worx submersibles maintain full responsiveness and power at all times, making docking alongside another vessel a simple task.
