Tour the World’s Most Luxurious Submarine Superyacht

If yacht owners really want to put everyone at port to shame, they should consider sailing on the Migaloo Private Submersible Yacht. A concept yacht created by Migaloo, an Austrian design and engineering firm, the line of luxury superyachts offers a range of bespoke underwater crafts that vary in size. After sailing the new Migaloo submersible yacht on the water, owners can close up the decks and turn the craft into a fully operational submarine.

“What we are attempting to do is to create a living space where exterior and interior interact in harmony,” says Christian Gumpold, managing director and head of design at Migaloo. With rooms that open to the ocean for dining alfresco while above water, and large viewing galleries for taking in the marine life when submersed, the Migaloo creates that harmony. What’s more, the firm reaffirms its focus on luxury with optional amenities that include helipads, swimming pools, movie theaters, elevators, wine cellars, libraries, and private terraces.

Of course, safety is a major focal point as well. Each superyacht will be built to U.S. Navy SUBSAFE safety standards, which ensure that the interiors will stay watertight and the vessel can recover from unanticipated flooding. According to Migaloo, solitude is a major point of interest for yacht owners, which is why the ability to dive beneath the surface and out of view might have great appeal. “Privacy is a big issue on superyachts,” says Gumpold, “our answer to this concern is simply submerging the vessel into complete privacy.”

As impressive as all that may read, we’re only scratching the surface. Migaloo is billing the M5 as the world’s first luxury submersible superyacht. The Graz-based firm promises it will go all out to deliver the sort of amenities its ultra-ultra-rich clientele expect. It intends to work with customers to design the interior of their dreams, but they can expect an opulent dining room with room for 36 guests and panoramic glass walls, a curated wine cellar, and a technologically advanced cinema. There will also be two swimming pools, a jacuzzi and—because this is a superyacht we’re talking about—a helipad.

When the M5 is surfaced, there is also a healthy stable of water toys for the owner and their guests to enjoy. These include five Sea-Doo Jet-Skis, Seabobs, Zapata Racing flyboards and hoverboards, and everything else you need for paddleboarding, kitesurfing, and kayaking. There are also two custom Midget-Submarines, two submersibles, and several ROVs and UUVs. There’s little risk of getting bored onboard the M5.

Written by Rachael Steele

At the Monaco Yacht Show 2022, Dutch shipyard U-Boat Worx unveiled ready-to-construct concept designs for a 37.5m/123ft luxury submarine yacht: ‘NAUTILUS’.

Luxury submarine yacht Nautilus Blue 3qrt Back Tender

Submersible yacht concepts have been created before, however, none have made the leap from an idea into reality. U-Boat Worx intends to be the first, using the company’s experience in creating small submersibles to engineer and launch a fully certified submersible with all the comfort and indulgences expected aboard a yacht.

Luxury submersible yacht NAUTILUS top view

Submersible motor yacht NAUTILUS runs on diesel-electric power and can reach a depth of up to 200m/656ft, with 10 windows 4m/13ft wide giving a unique view of the underwater world – perfect for guests who cannot dive into such depths yet still want to see the wonders of destinations such as the Red Sea , the South Pacific and the Caribbean .

Nautilus Luxury submersible yacht profile

An added advantage of underwater capabilities means no more seasickness: In rough seas, NAUTILUS can simply dive below the surface and continue the journey in comfort. The NAUTILUS has a surface speed of 9 knots and an underwater speed of 4 knots. She can stay under the waves for up to four days, or for a total of six hours while cruising.

Above water, guests have access to alfresco facilities including a sundeck, bar, pool, dining, lounging and sunbathing facilities. All of this is retracted before going underwater.

Nautilus – Luxury submersible yacht

A pressure-resistant electrical tender (named ‘ARONNAX’) is stored under the aft deck and will remain outside while diving. ARONNAX can be used for transporting up to five Scuba divers underwater, to and from their destination.

The interior layout is fully customisable; however, the standard layout offers a 50m²/538ft² lounge and dining area, galley, plus guest accommodation over 5 cabins: 1 Master suite and 4 further guest cabins. The crew accommodation provides for 6.

The price for a NAUTILUS of your own starts at €25 million, and once commissioned, her Owner can expect to receive her within 30 months.

Meet Carapace - superyacht which transforms into a submarine

Meet Carapace, a 78-meter-long, ultra-luxury yacht that looks like it fell out of a James Bond movie…

Conceptualized by thirty-four-year-old Italian designer, Elena Napi, this yacht moves through the water like a normal ship, but can also be transformed into a fully functional submarine. The idea behind this radical yacht design may remind you of Captain Nautilus and sounds like the perfect billionaire toy.

The decadent hybrid ship is currently under development in Italy and is expected to be completed by 2021. According to the designer, Carapace has a maximum floating speed of 16 knots, so it can sail on a regular basis, as well as all other yachts of sailing dimensions, while it can be transformed into a submarine with a maximum depth of 300 meters.

As Elena states, the luxury hybrid ship has a lightweight aluminum superstructure and is powered by a diesel-electric powertrain, with a fuel cell system. “The Carapace Yacht is designed for both private and public markets. Its interior offers top-notch amenities such as a VIP cabin, lodge, spa, bar and gym. The company working on the development of this ship says it is designed to accommodate passengers with reduced mobility. ” For now, we do not have information yet on how much this yacht will cost when it's finished, but we believe the price will reach several hundred million dollars

What an underwater superyacht could look like

by Mariska Buitendijk | Oct 17, 2022 | News , Ship design , Shipbuilding , Submarines , Yachts

Dutch U-Boat Worx has revealed the design of a 1250-tonne, 37.5-metre yacht submarine, the Nautilus. The underwater superyacht could be built within thirty months and comes with a price tag of EU 25 million.

Since Jules Verne’s 20,000 Leagues Under the Sea came out in 1870, people have been dreaming of a luxury yacht with dive capabilities. Since then, inventors produced a lot of impressive concepts. Unfortunately, not one of these designs has ever been realised.

U-Boat Worx designs and builds small submersibles, and says it has now finally succeeded in engineering a realistic combination of luxury and safety in a fully certified private submersible.

The diesel-electric Nautilus has a depth rating of 200 metres, with a surface cruise speed of 9 knots and an underwater speed of 4 knots. Once ordered, the company can deliver a Nautilus within thirty months.

Yacht features

When functioning as a boat, the Nautilus offers a massive sundeck equipped with a freshwater pool, a bar, and a luxurious dining table. This al fresco arrangement is retracted before the submersible slips below sea level.

The Nautilus interior features a 50-m2 dinner and lounge area with four circular windows. Each with diameters close to 4 metres. The proposed design has a master bedroom and four staterooms, as well as sleeping quarters for up to six crew. The vessel will also be fitted with a fully equipped galley, while the interior layouts are fully customisable.

Underwater for four days

The superyacht submarine will be able to stay under water for up to four days. At cruise speed, the underwater endurance is six hours. When not in use, the Nautilus can be docked at any quay that can accommodate its 6.5-metre draugh. The Nautilus has a starting price of EUR 25 million.

A newly invented, completely pressure-resistant electrical tender is stowed under the Nautilus’ aft deck and will stay outside while diving. This tender, the Aronnax, may also be used for transporting five scuba divers underwater to the intended dive spot.

‘People that have decided to buy a yacht will now have to consider if their vessel of choice can also dive down to 200 metres,’ says U-Boat Worx Chairman and Founder Bert Houtman. As an added bonus, the Nautilus combats seasickness. Houtman: ‘If the sea becomes too rough, you simply dive and continue your voyage in comfort.’

The best submarines for superyachts

More than 80% of the world’s oceans remain unexplored but discovering the depths might be easier than you think. Built to cater from one to six guests and tailored to fit the weight and height restrictions of a superyacht tender garage, a personal submarine lets you explore the underwater world like never before.

U-Boat Worx Nexus

Dutch submersible manufacturer U-Boat Worx has added a new nine-person model to its line-up of deep-diving subs. With a maximum depth of 200m, the Nexus can operate for 18 hours, diving up to 10 times a day. Two designs have been revealed in the new series, both featuring an extra-large elliptical acrylic pressure hull and revolving seating arrangement for cinematic style viewing. An extra-large hatch has also been included on board the Nexus, allowing passengers to keep their dignity while entering and exiting the submersible.

Triton 600/2

Meet Triton's smallest and lightest submersible to date. Weighing just 2,500kg and standing 1.47m tall, the 660/2 packs the power of Triton's pro flagship submersible into a svelte new design which can slot into most superyacht tender garages without a hitch. The perfect size for owners looking to pilot their own submarine, two people can dive down to a depth of 200 metres and power along the seabed at a top speed of four knots for up to six hours. With numerous customisation options on offer, you can even tailor the sub to match its mothership.

NEMO Submersible

NEMO is the smallest member of the U-Boat Worx fleet, offering a slick, deep-diving sub in a lightweight 2,500kg package. Designed with the yacht market in mind, the NEMO submersible can dive to depths of 100 metres with room for two, and at 2.3 metres wide requires less storage space than a pair of Jet Skis. Meanwhile, a simple launch and recovery system allows for ease of operation thanks to a single lifting point. At the 2021 Monaco Yacht Show, U-Boat Worx a single-seat version of the NEMO submersible named NEMO 1.

uboatworx.com

This three-person submarine is capable of diving to 457m and offers some clever onboard extras. The Aurora-3C is able to tilt at surface, providing a stable platform for boarding when stepping across from a superyacht. And by moving the hatch away from the top of the window and into a separate compartment, the model offers a greater field of view. The submarine's low height and even lower hoist point make an ideal for setup in confined spaces – say a superyacht tender garage - without compromising on comfort, practicality, and performance. The Aurora-3C also offers extras including a robotic arm, HD video systems and a fly-out rover with HD camera. You can even customise the colour.

Project Neptune

Project Neptune is the result of a collaboration between submarine specialist Triton and British car marque Aston Martin. This three-person submersible combines all the practical and technical elements of deep-sea exploration with a level of finesse and style that’s quintessentially Aston Martin. Able to dive to 500m, Project Neptune offers a bulbous cabin for panoramic views and a sleek, compact multihull silhouette for optimal speed and style under the waves. While a top speed of five knots might not sound like much – particularly for an Aston Martin – it’s actually four times the acceleration of Triton’s flagship 3300/3 submarine. Inside, a custom interior features hand-stitched leather and carbon-fibre trim.

U-Boat Worx Super Yacht Sub 3

Known for their reliable, workhorse subs used for scientific exploration, Dutch builder U-Boat Worx has a personal submarine specifically for superyachts. The Super Yacht Sub 3 is compact, lightweight with a virtually unimpeded view underwater. With a length of less than 3.2m and weighing 3,800kg, the sub is easy to fit on board, and can dive to 300m with a top speed of three knots. A retractable freeboard extender makes on-the-water boarding a breeze while the interior is kitted in out plush leather seats for comfortable cruising. Bonus features include a Bluetooth sound system and a cold-storage box.

Seamagine Aurora-6S

Created to give guests a completely immersive experience in the watery world below, SEAmagine’s Aurora series of submersibles features a massive glass bulb for unparalleled views as she dives up to 1,000m at a max speed of three knots for eight hours. The Californian company’s largest luxury sub, the Aurora-6S, seats five passengers and one pilot. A single-point hoist makes for uncomplicated launching, while an ergonomically designed aft section and telescopic handrails ease boarding. The entire set-up is ideal for deep-sea exploration with the family in tow. The Aurora-6S’s weight and size can be customised to suit the mothership, as can the colour.

Triton 1650/3

Triton's 1650/3 is the world's lightest and most compact three-person submersible. Designed to launched from a standard superyacht tender garage, the model takes up less space than a pair of Jet Skis when stowed but can still dive to depths of 500 metres.  Whether exploring coral reefs or shipwrecks, pilots and passengers will benefit from near 360-degree views thanks to a bulbous acrylic cabin and when it's time to resurface, a single lift point makes recovery a breeze.

The most compact private submarine

Super yacht sub 3.

Versatile, smart and capable with a design that will satisfy the highest expectations of discerning superyacht owners.

The fully acrylic hyper-hemispherical viewport gives you the best panoramic view of the underwater world possible.

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.

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.

The powerful thrusters and the excellent manoeuvrability of the Super Yacht Sub 3 boost superior surface performance. You will be able to go faster, manoeuvre better and expand your operational window.

This compact ultra-wide (130 degree) field of view instrument has a range of 100 meters acting as a second set of eyes when navigating the subsea terrain.

External equipment comprising a selection of subsea robotic arms together with work platforms and collection baskets can be installed on most of the U-Boat Worx models.

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.

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

The acrylic pressure hull accommodates two luxurious leather seats which can be customized to your taste.

The best dive experience

This submarine is aimed at the yacht markets where an ever-growing number of seaboard owners are discovering the world below the waterline. This compact and lightweight model delivers both performance and luxury.

Clearest View

The ground breaking pressure hull design provides a virtually unimpeded view; everyone on board can easily see the hidden secrets of the deep.

Unparalleled comfort

With the U-Boat Worx Super Yacht Sub 3, we have aspired to create the ultimate in luxury interior design. When onboard a Super Yacht Sub 3, guests enjoy exhilarating views from a sumptuous chair in a comfortable air-conditioned environment with variable airflow, adjustable from each seat. You can also enjoy music from a hi-fidelity Bluetooth sound-system and even chill your favourite drinks in a cold-storage box.

Unrivalled mission-adaptability

The Super Yacht Sub 3 outperforms on every level – flexibility, agility, economy and power. This exceptional submersible features the Freeboard Extender and other smart engineering solutions.

Designed from concept to be dive-ready, U-Boat Worx has kept pre-dive checks to the safest minimum, allowing for quick and easy deployment.

SPECIFICATIONS & FEATURES

• Depth 300 m · 1000 ft
• Occupancy 2 passengers · 1 pilot
• Weight 3,800 kg
• Endurance 12 hours
• Length 320 cm
• Width 244 cm
• Height 174 cm
• Battery 21.6 kWh
• Propulsion 4 X 6 kW
• Speed 3 knots

Lithium-ion battery technology

Freeboard extender, manta controller, marlin controller, auto-heading, omni-directional operation, container fit, single lifting point.

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.

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.

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.

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.

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.

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.

This submersible is designed to fit in a shipping container. Perfect for when the submersible needs to be transported to and deployed in different locations.

The single lifting point makes launch and recovery quick and easy. By only having to attach at one point – to the crane – you create a safer environment. With the rapid-release and efficient-connect lifting gear, you can be quickly in and out of the water.

Maximum depth protection

Deadman's switch, drop weight, safety buoy, dnv certification.

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.

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.

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

A very advanced USBL system is available that relays GPS data to the submersible’s on-board computer via integrated underwater modems. Piloting with real time positioning and supporting text data provides for accurate and efficient navigation. The DVL (Doppler Velocity Log) delivers real-time ground speed and position data linking to the on-board computer system.

Certified by leading classification society, DNV, 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.
