As Far As You Can Sea: World’s Largest Superyachts

Multimillion-dollar mega yachts.

by Emma Treagus Published on February 2, 2024

At Luxe Digital, we independently research, review, and recommend products we love and that we think you will love, too. Learn more about how we curate the best products for you .

With onboard swimming pools, cinemas, helicopter landing pads, and spas, the world’s largest superyachts have more facilities than your ‘average’ five-star hotel.

Owned by some of the world’s wealthiest people—along with a few anonymous owners who’d prefer to keep their luxury transport a secret—these mega yachts redefine the word “boat” into something indescribably sleek, stylish, and seriously impressive. 

If superyachts are your thing, you’ll want to read on for all the facts and figures on all of the largest yachts in the world.

The 26 largest yachts in the world

Multimillion-dollar mega yachts: our ranking methodology.

A superyacht or mega yacht is typically a motor yacht or sailing yacht with a length of 30 meters (100 feet) or more. For this ranking, we looked at the superyachts and luxury expedition mega yachts that are used privately or made available for charter. We excluded so-called ‘residential superyachts’ (think Njord and The World), which are essentially luxury apartment buildings at sea where people own private residences inside the superyacht rather than the whole yacht. By researching diverse, reliable sources like Wikipedia and the Superyacht Times, we compile a list of the largest yachts in the world.

Curious about other striking superlatives? Check our round-up of the most expensive cars in the world and the most expensive private jets in the world . They are both perfectly good alternatives to owning a yacht. And if you prefer to stay home, we’ve ranked the biggest homes and the most expensive houses in the world to give you some inspiration too.

26. Y721 (aka Koru) | 417 feet—127m

Ever wonder where Jeff Bezos spends his downtime? As of today, we’re predicting it to be on his $500 million superyacht. Y721—nicknamed Koru—is 127m long. And featuring three sky-high slender masts, Koru is said to be the largest sailing yacht in the world . 

With dark exteriors and natural wooden decks, Koru is inspired by another one of Bezos’ yachts—the Black Pearl. The clean lines and classically curved bow speak to an understated elegance despite the yacht’s mammoth size. While a long line of portals indicates at least 9 guest cabins. In light of all the secrecy surrounding Koru, we doubt Bezos will ever charter her out, but we can still dream.

25. Al Mirqab | 436 feet—133m

Adorned with cascading chandeliers and gold accents, Al Mirqab is renowned for its unrivaled interiors. Surrounded by suspended glass artworks, a grand staircase floats throughout the four floors. And inspired by authentic Arabian styles, the magnificent superyacht is reminiscent of a magic carpet ride through the seas . 

Built for the former Prime Minister of Qatar, Peterswerft-Kusch spared no expense in delivering Al Mirqab to an impossibly high standard for luxury. The large swimming pool is a standout feature as it opens up into the sea, creating the ultimate playground for adults. Al Mirqab has a capacity for up to 60 guests and is manned by an equal number of crew. Although you have to be invited by the politician himself as Al Mirqab isn’t available for private charter.

24. Serene | 439 feet—134m

Adeptly named, the magnificent superyacht embodies the serenity of a life at sea. Serene was built in Italy for a Russian owner in 2011. She was leased to Bill Gates for the Summer in 2014 for $5 million per week. 

Designed by Reymond Langton, the 134m mega yacht marries elegant sophistication with state-of-the-art technologies. The seven decks leave ample space for guests to soak in scintillating views. While the underwater viewing room—nicknamed the Nemo room—is a permanent gallery of resplendent sealife. The real-life snow room makes up to four inches of snow. And whilst this may seem odd when your billionaire boss asks for snow—you make it snow.

23. Crescent | 445 feet – 136 m

Yet another Lurssen masterpiece, Crescent pays homage to classic naval designs with traditional architecture and elegant interiors. Formerly named Project Thunder, she was built in Germany and delivered to Igor Sechin in 2018. The Russian oligarch’s superyacht was seized by Spain after sanctions were placed on Russia in 2022. 

Crescent features low bulwarks and full-height windows to maximize the view from the center of the boat. Her distinctive wing station provides unrivaled views for up to 18 guests. But don’t get your hopes up—Crescent is strictly for private use only and isn’t available for charter. 

22. Savarona | 446 feet – 136m

Savarona is the second-largest yacht built by Blohm & Voss and spends most of her time in the Mediterranean. This luxury superyacht is one of the oldest in the market — a perfect fusion of traditional charm and modern facilities. 

Previously named Gunes Dil, Savarona was designed by Cox & Stevens, with interior design carefully handled by Donald Starkey. She’s available to charter on a weekly basis and has been refurbished over the years. Back in the day, her cost price was $4 million, and in 1989, she was chartered by Kahraman Sadikoglu, owner of the Turkish Sadikoglu Group, who spent an estimated $50 million on refurbishing her from top to bottom.

21. Flying Fox | 446 feet – 136m

Flying Fox is known as the most expensive charter yacht in the world , and a week aboard will set you back around $3 million. Chartered by the one and only power couple Beyonce and Jay-Z in 2021, it’s filled to the brim with all of the luxury facilities you could ever possibly want. 

The Flying Fox is rumored to be owned by Jeff Bezos, although that’s a claim that’s never been totally certified. She spends most of her time in the Mediterranean, specifically Cannes, Capri, and Sardinia, although she’s recently visited Norway, too. She can accommodate the largest helicopters on the market, and it reportedly took more than 50 meetings with her owner for interior design to be completed.

20. Rising Sun | 454 feet – 138m

The Rising Sun’s original owner, Larry Ellison, CEO of Oracle Corporation, sold her in 2010 as he considered her too large. Famously used by David Geffen for self-isolation, Rising Sun has also been a popular hang-out spot for celebrities like Oprah Winfrey and Beatrice, the Princess of York. 

She’s a Superyacht with impressive attention to detail like interiors kitted out in teak and onyx and endless features like a full gym , a large wine cellar, a sauna, and a spa. She’s got a full-size basketball court that doubles up as a helicopter landing pad and a private cinema for those long evenings spent at sea.

19. Al Salamah | 457 feet – 139m

Al Salamah is part of the Omani Royal fleet and started her very secretive life in Genoa. Known as the world’s biggest superyacht right up until 2016, she’s a sleek masterpiece of a ship, with a distinctive cream color and beach club design. 

Al Salamah does everything in multiples, from the five galleys onboard (the main galley, a bakery, a crew galley, an owner’s diet galley, and an Arab galley), three hospitals (one for the owner, one for guests, and one for the crew) and 2,000 sqm of floor space. She was put on sale briefly for $280 million USD, before being delisted and instead given as a gift to the Crown Prince of Bahrain. 

18. Solaris | 458 feet – 139m

Everything about Solaris was supposed to be kept a secret when she was being built—a secret that didn’t last long when her huge size was spotted undergoing sea trials in the North Sea. One of this Superyacht’s main attractions is her beach club on the top floor: the perfect spot for relaxation during those long days out at sea. 

That beach club comes complemented with endless other stylish amenities, like a large helipad, sun deck, and a crane to launch tenders, toys, and subs. Interior design is largely unknown, but, if it’s anything as sleek and white as its exteriors, it’s sure to be impressive.

17. Scheherazade | 459 feet – 140m

Two helicopter landing pads, two outdoor Jacuzzis, and two outdoor fire pits: Scheherazade doesn’t hold back with not only the essentials but also the luxuries. Previously named Lightning, “Scheherazade” is mostly associated with a female character in the Middle Eastern folk tales in the series One Thousand and One Nights. 

Not much is known about this superyacht, and even her birth and building process were referred to under a codename: Project Lightning. No one involved in her creation, even Lurssen, has revealed anything about her interiors or her owner. All that’s really known is that she sailed from Germany to Norway initially after completion. 

16. Ocean Victory | 460 feet – 140m

Ocean Victory has traveled all over the world, from Europe to Southeast Asia and back again. Owned by Russian billionaire Viktor Rashnikov, she’s the upgraded vessel to follow his purchase of the 76-meter Ebony Shine. 

She’s one designed with pure luxury in mind, from the six individual swimming pools onboard to the 300-square meter spa area. She’s beautiful both inside and out, with a unique concept designed by Espen Oeino and interior designer Alberto Pinto. The largest superyacht ever built in Italy, Ocean Victory shows some of the finest in the world when it comes to premium quality adventures at sea.

15. Yas | 463 feet – 141m

Yas is known best for its seamless and rather unusual design — one that’s a little different from most superyachts out there. The owner of Yas wanted a yacht that lived up to his own heritage; one with a backbone reminiscent of the navy and with abstract lines throughout. 

He chose an existing boat in Abu Dhabi, which was deconstructed within the region before being shipped off and renovated into the wonder that it is today. The Yas yacht was originally a Dutch navy frigate, which you’d never guess from strolling around onboard today.

14. Nord | 465 feet – 142m

Nord’s distinctive bow design has never been seen before on a yacht. That’s one of the first things you’ll notice about her. The next thing you’ll notice is her unusual design, which verges on battle-esque and has been called “ a warship wearing a tuxedo ” by Dan Lenard of the Italian design studio Nuvolari-Lenard. 

She’s one of the best superyachts out there for fun, with a sports and diving center on the lower deck, a swimming pool higher up, overlooking the ocean, and a fleet of tenders. She was designed for global exploration: a yacht that will calmly cruise her way all across the world.

13. Sailing Yacht A | 469 feet—142.8m

Challenging the status quo and pushing design boundaries, Sailing Yacht A is an enigma. The sail-assisted superyacht was built in Germany and delivered to Russian tycoon Andrey Melnichenko in 2017. However, she was seized by the Italian police force, Guardia di Finanza, in 2022 after sanctions were placed on Russian businessmen following Russia’s invasion of Ukraine. 

Distinguished by soaring rotating carbon fiber masts, Nobiskrug’s hybrid approach to superyachts makes Sailing Yacht A more eco-conscious than other luxury yachts of her size. The u nderwater viewing pod molded into the keel speaks to her unrivaled innovation. And many balconies are enclosed by some of the largest pieces of curved glass ever made. 

12. El Mahrousa | 478 feet – 146m

El Mahrousa had a few different names in her time, ranging from the translated “The Protected” to El Horreya, which in Arabic translates to “Freedom.” It’s not surprising that she’s had more than one name when you take into account her age. As the oldest superyacht in the world, she’s undergone a lot of restoration over time, including multiple lengthenings and faster engines. 

She was renamed back to El Mahrousa in 2000 and gained even more recognition for being the first ship to cross the new Suez Canal extension in 2015. Back in her original days, she was built on the River Thames and took her first trip in 1867.

11. OK | 479 feet—146m

Delivered in Japan in 1982, OK is one of the largest and most unique superyachts in the world. Sprawling over 479 feet, the water giant is engineered to submerge almost seventy percent. This is accredited to the work done by Karmarine Shipyard. While the majority of the vessel was built by Oshima Shipping, it was privately converted to a semi-submersible yacht in Turkey. 

The superlative finishing on OK superyacht was designed by Timur Bozca, winner of the Younger Designer of the Year award in 2015. The blueprint being as many games as possible. The extraordinary vessel has the uncanny ability to hold over seventy toys, including a sailing yacht, a sea plane, tenders, buggies and even a tennis court.

10. Opera | 480 feet—146.4m 

Like many of the most majestic water titans, Opera was delivered by Lurssen in Germany and built for Abu Dhabi royalty. This time, the owner is Sheikh Abdullah bin Zayed Al Nahyan, son of the founder of the United Arab Emirates. And while it may not be quite as astronomical as Lurssen’s previous builds—Azzam, Blue and Dilbar—the streamlined vessel is equally impressive onboard. 

The three-story superyacht proves large enough for a pair of helipads and two swimming pools, amongst many other toys, while simultaneously making room for up to 48 guests and 80 crew members. When it comes to the interior, details are sparse, but we do know that it was designed by Terence Disdale, a London firm renowned for creating bespoke luxury spaces. 

9. Prince Abdulaziz | 482 feet – 147m

The Prince Abdulaziz’s yacht was ordered by King Fahd, who named her after his son Prince Abdul Aziz. Now, she’s owned by his brother, Abdullah. Just one of the yachts owned by the Saudi royal family, she’s spotted frequently throughout Europe, especially in Cannes, where the royal family owns a property. 

She’s been redecorated once — in 2007 — in a project that took 15 months to complete, without even taking into account the rest of the ship’s upkeep. The Prince Abdulaziz is known for its combination of bold colors and fusion of traditional and modern design, thanks to its influence from the late David Hicks.

8. A+ | 483 feet – 147m

What do you do when the name “A” is already taken for your superyacht? Choose the next closest thing: A+. Previously named Topaz, this superyacht was the world’s fourth-largest luxury yacht when she was built, before being stripped of that particular title only a few years later. 

Nevertheless, she’s a seriously impressive superyacht, with endless facilities like a large jacuzzi, double helicopter landing pads, a swimming pool with a swimming platform and underwater lights, as well as a fitness hall, cinema, and a large conference room. She’s also well equipped with water toys, like jet skis, inflatable boats, a catamaran, and even a mini-submarine.

7. Al Said | 508 feet – 155m

Another Superyacht built, shrouded in secrecy, Al-Said was referred to as “Project Sunflower” the entire time she was being created, right up until she was delivered to her owner in 2008. Not much is known about Al Said, from her movements through to her amenities — although she is known to have a huge concert room with space for a full 50-person orchestra. 

Currently, she’s flying the flag of Oman and has spent a lot of time in its surrounding waters. Her interior was styled by British designer design house RWD, with exterior design being credited to Espen Oeino. When she was delivered to the Sultan of Oman, she replaced a previous ship of a smaller size. 

6. Dilbar | 511 feet – 156m

Dilbar, or Project Omar, as it was originally known as, is another superyacht designed with the help of exterior expert Espen Oeino, but with interiors strikingly designed by Andrew Winch. Dilbar is famously known as the world’s largest yacht by gross tonnage (interior volume) but as the fifth-longest superyacht in the world. 

She’s home to a spa pool and beach club, as well as a large private cinema, spacious cabins set high on the main deck, a spacious dining room, and a salon with its own piano. She’s just as classy and beautiful on the inside as she is on the outside.

5. Blue | 527 feet—160.6m

Sunday blues simply cease to exist on one of the world’s most extravagant superyachts. The elegant behemoth was built for member of the ruling family of Abu Dhabi and billionaire, Sheikh Mansour bin Zayed Al Nahyan in 2022. Valued at over $600 million, Blue is one of the most expensive superyachts in the world. And with a strong emphasis on the environment, this superyacht is also one of the most sustainable. 

Blue strives to be as environmentally friendly as possible. She is equipped with a highly efficient Diesel-Electric Hybrid Propulsion Concept developed by Lürssen’s own engineering specialists. And the wastewater treatment plant allows water to be disposed of in drinking water quality.

4. Dubai | 531 feet – 162m

Dubai had multiple names in the planning stages—including Panhandle, Platinum, and Golden Star. Owned by the ruler of Dubai, it was aptly named after its home country and comes with all of the luxurious amenities you’d expect from such a name. 

The Dubai comes complete with a huge swimming pool and two jacuzzis. Further down, you’ll find a large dining room with striking blue and burgundy decor and space for up to 90 guests. Dubai usually spends her time moored at Sheikh Mohammed’s private island in front of his summer palace in Dubai. She’s basically the definition of a floating palace.

3. Eclipse | 533 feet – 162.5m

It took around five years for Eclipse to be built from start to finish. While she was always designed to be a huge, luxurious Superyacht, the focus was more on decking it out appropriately rather than breaking any records. An award-winning superyacht, she’s incredibly spacious, with endless rooms to explore and a sleek, neutral color palette running through. 

The Eclipse’s owner, Roman Abramovich, was more focused on facilities: he wanted more than one helicopter pad and a large swimming pool, too. Other than that, designer Terry Disdale had free reign for the rest of the superyacht. It’s just as much a clean piece of architectural styling as it is a stunning experience on deck.

2. Fulk Al Salamah | 538 feet – 164m

Fulk Al Salamah translates to “Ship of Peace” and that’s something that sounds like a given when you’ve taken a look at this superyacht’s incredible layout. Developed under the codename Project Saffron, Fulk Al Salamah is more of a support vessel than she is a typical superyacht. 

While she might still come complete with all of the necessities for a particularly relaxing voyage, she’s more so known for being a transport ship for the Royal Navy of Oman. She’s also used as a sort of friendship boat — pun intended — and is often sailed across the world with the intention of strengthening ties with the Sultanate. In some ports, influential people are welcomed onboard.

1. Azzam | 590 feet – 181m

Most superyachts in the top 10 category have a few mere inches between sizes, but the Azzam shoots far ahead with a large amount of extra length. The largest superyacht in the world, she was never designed to win the title — rather just to be a sleek and elegant vessel. Azzam was crafted backward, with the plans for her interior confirmed long before her exterior was fully signed off. 

Her length only came to be as such to incorporate everything required for the interiors, which added an extra 35 meters to her overall size. She’s also designed to look smaller than she actually is, with a blend of indoor and outdoor living. It took more than 4,000 people to build Azzam , clocking up six million man-hours over a period of four years.

The largest yachts in the world: Conclusion

The largest yachts in the world are:

• Azzam—590 feet
• Fulk Al Salamah—538 feet
• Eclipse—533 feet
• Dubai—531 feet

The most expensive yacht in the world

The fact that the History Supreme, the world’s most expensive superyacht, comes coated in gold, is only part of the reason for its high cost. A superyacht with a real-life Midas touch, it was sold to an anonymous Malaysian businessman for $4.8 billion. 

Robert Kuok, the richest Malaysian businessman, is the rumored owner of History Supreme, but no one has confirmed for sure. The History Supreme also comes with plenty of other impressive touches: a master bedroom decked out in platinum, a wall feature made from meteoric stone, and a genuine T-Rex dinosaur bone, to add to the list. 

She took three years to build from scratch and comes with 10,000 kilograms of solid gold and platinum. Other seriously luxe features are her 68 kilograms 24-carat gold Aquavista Panoramic Wall Aquarium and a liquor bottle adorned with a rare 18.5-carat diamond . The base of the vessel comes wrapped in gold, too.

The world’s biggest yachts – what’s behind the growth of the gigayacht

• Helen Fretter
• March 14, 2017

The last few years have seen launches of some of the world's largest yachts, truly gigayachts. Helen Fretter delves into the world of the gigayacht

Dwarfing not only any other yacht that happened to be on the River Eider, but even the buildings along the foreshore, the monolithic Sailing Yacht A made quite an impression when she was launched from the Nobriskrug yard in Hamburg in the autumn of 2016.

The 142m, eight-deck behemoth is the archetypal ‘gigayacht’, phenomenal not just in her dimensions but also in her radicalism.

The Philippe Starck-designed Sailing Yacht A , with her 20m freeboard, begs the question: is she even a sailing yacht? The last yacht to divide opinion, and attract the shock and awe of the non-sailing public in the same manner was Maltese Falcon , the glossy, experimental megayacht designed for Silicon Valley venture capitalist Tom Perkins.

But the Falcon was launched a decade ago, and Sailing Yacht A is just one of a crop of extraordinary gigayachts, or sailing superyachts of 80, 90 or 100m plus, to touch the water in 2016.

Besides the 142m Sailing Yacht A , another three-masted design was launched from OceanCo this autumn, the 106m  Black Pearl , which looks set to become the largest sailing yacht in the world – for a while at least. Black Pearl represents a modern evolution of the rotating Dynarig pioneered by Maltese Falcon . Meanwhile in the spring, the largest Bermudan rigged yacht ever launched, the 86m ketch Aquijo , powered through sail trials in preparation for a global adventure.

There are more in the pipeline also. Royal Huisman announced this autumn that they had been commissioned to design and build the 86m Project 400 , another three masted design, this one more conventionally rigged. A proposal for the 114m Endurance has just been unveiled, an explorer concept designed to be able to cruise unassisted for three months. There is also the 86m Komorebi , an experimental wingsail-assisted hybrid trimaran design from the French multihull experts VPLP.

Rise and rise of the gigayacht

Why the sudden flurry of these stratospherically ambitious projects? In truth, it is not that sudden – initial pitches for what ultimately became Sailing Yacht A were invited back in 2008, and pre-studies began in 2011. A decade between projects seems rather shorter when design and build takes at least five years – gigayacht owners may be exacting, but they also have to be extraordinarily patient.

The 141m four-masted Dream Symphony is currently in build out of wood in Turkey, and includes vast living accommodation, and a swimming pool that converts to become a helipad platform.

What is remarkable, though, is how rapidly the yachts have grown in size – raising the upper ceiling from 88 to over 140m in a decade. Dutch naval architecture firm Dykstra has been instrumental in many of the world’s most innovative megayachts, including Sailing Yacht A , Black Pearl , and Maltese Falcon .

Managing director Thys Nikkels comments, “Ten years ago a big boat was a very different size than a big boat is now. I can still remember when I started working in ’91 a 40-metre yacht in those days was a big boat. In the mid-90s we started to design the yacht Athena , which we thought was the biggest boat we were ever going to see in our lives, as a sailing yacht she was 80 metres on the water.”

The largest single sloop rigged yacht in the world remains Mirabella V , launched back in 2003 and since renamed (and slightly lengthened during a refit) M5 at just over 77m. Rob Doyle, who worked on the project led by Ron Holland, recalls:

“We started designing her 17 years ago now. We hit a very natural sweet spot with Mirabella and that’s why it has taken so long for other boats to suddenly go over her length and over her rig height.

“ Mirabella still has the highest ‘P’ measurement [distance from boom to top of mast] and the longest boom in the world, though there are taller masts now.

“She set a bar and we didn’t realise we’d actually set it. It came down to a ratio of the rig weight to the draught and the keel weights, and everything else to be able to carry that amount of sail and that ballast to satisfy the rules.

“We pushed technology a lot – about 16 companies went bust over Mirabella  because the jump was so massive. We were jumping from a 64m to a 75m [yacht] and that jump was like learning to fly, then going to the moon!”

Video of Sailing Yacht A, the world’s largest sail-assisted vessel, during early sea trials

This video footage of Sailing Yacht A shows her with her towering free-standing masts and illustrates the jaw-dropping scale of the world’s…

A look on board the extraordinary 86m Aquijo, the world’s largest ketch

The largest Bermudan rigged ketch ever launched, the 86m Aquijo was designed by Bill Tripp and launched last year. The build came…

Ken Freivokh, who was responsible for the radical styling of Maltese Falcon , also points out that after the much publicised launch of the Falcon many buyers did not want to be seen to be emulating Tom Perkins’s unique style, preferring to wait, or opt for a conservative design. After the Falcon , Freivokh’s next radical Dynarig yacht was Black Pearl , which he began work on six years ago. At 106m Black Pearl dwarfs Maltese Falcon , with a 2,700GT volume that puts her just under the key 3,000GT limit.

Surprisingly, Dykstra’s Thys Nikkels says that the Dynarigs being built today are not markedly different to the one developed for Maltese Falcon a decade ago. “In concept it is not very different. In detail there are a number of improvements that have been made.

But Maltese Falcon was – for her time – years far ahead and she proved to be very successful in sail handling and sailing, so there are not many improvements to be done. Nowadays you just have different materials you can use, or different electronics and software systems that you can use for control.”

Maltese Falcon, launched in 2006, pioneered the Dynarig concept utilised on many of the next generation of larger gigayachts.

Sail handling

Meanwhile a decade of development in superyacht rigs and sail systems, means that Aquijo ’s owner could opt for a conventional ketch rig, which can deploy over 3,000m2 of sails in around six minutes.

Sail handling routines are necessarily different – the jib is furled when tacking. “Vitters organised a nice system that keeps just a nice amount of tension on the jib sheets furling in and out so that they are not flailing about,” explains Aquijo ’s designer, Bill Tripp. “So it’s not a dinghy tack, but it is safe and orderly.

“The spinnaker is on a fast furler and furls up in 30 seconds, making gybes less complex. There is the ketch choreography of bringing the main and mizzen in, but the steering is precise and there is no need to put too much sail up for the conditions.”

Aquijo master cabin

The forces generated on yachts such as Aquijo may be enormous – mast compression can reach around 580 tons – but are no longer beyond the realms of riggers’ experience. “When we started building boats like Saudade [the 2009 45m Wally], 14 tonnes was a very big load. Once we understood racing these boats, and understood they were controllable, you can take another step.

“We were delighted when sailing Aquijo upwind in a lot of breeze that the load on the mainsheet was showing around 12 tonnes. It’s 2:1 so that’s 24 tonnes. I’m not saying that’s not a massive load, but it’s similar to what we have on Saudade ’s big sheet 1:1, and we have years of experience with handling that.” Custom built 40 ton carbon and alloy winches help manage the sheet loads.

Tripp notes that a Dynarig was never considered as an option. “What you’re really asking is do you want the ease of sailing or do you want to be able to access something exciting? And we wanted both of them.

“Sailors tend to like the more fundamental experiences, and when the technology allows them to access those more fundamental experiences, well that’s a great joy.”

Finding the limit

Just how big can a sailing yacht go? Five years ago plans were unveiled for a 101m sloop, with a single 125m carbon mast, which raised a few eyebrows and discussions over whether it might be possible. Malcolm McKeon worked on the proposal and says that it was the cost, rather than technical limitations, which put the brakes on the project.

“It was an evolving process. The owner has a 50m-plus sailing superyacht, and he wanted a new yacht big enough that he could put a reasonably sized chase boat on board. He wanted an explorer type sailboat that he could go to the Pacific on, and carry all his toys with him, and not have to have a support boat.

“The design started at 65 or 70m and it just grew and grew and grew until it got to 100m, and then it basically just got too expensive.

Recent sail trials on Sailing Yacht A saw the 1,464m2 mainsail unfurled from the 27.5m carbon U-shaped boom. Incredibly she is designed to heel up to a maximum angle of 12 degrees under full sail.

“The big problem with the large sail boats is the mast price goes up by a bigger proportion to everything else so the rig price becomes a much bigger percentage of the overall build. Technically it can all be done, it’s just the value of that part becomes a much more significant part and sometimes more difficult for an owner to accept.

“If somebody came to me and said they wanted to build a boat with a 200m mast I would think well, is that really possible? Certainly rigs up to 100m and a bit more I think are possible today, but where we’re going to go after that I don’t know.”

Rob Doyle points out that sailing superyacht owners pay around a 30 per cent premium over opting for a motoryacht, yet the boats lose around a third of the equivalent interior volume. However, for him the biggest limitations are the humans onboard.

“I think we are coming to a stage where we need a new type of rig, to be honest, to be able to safely deploy these sails without killing people. I think we are getting very close to where the metal meets the flesh at the deck level where the people and the guests are hanging around.”

With the ever-increasing winch and line speeds needed to handle the huge loads, serious hand and limb injuries can happen in the blink of an eye. “There is a moral hazard there that keeps playing on my mind,” says Doyle. “We are building very dangerous machines and we have to be very careful of people.”

The newly announced Endurance concept design is a 114m four-masted explorer design with a 6,000 mile range under power.

More prosaically, the bigger your gigayacht, the bigger the challenge of just getting on and off it. “Once you are getting to a stage where you can’t get into anchorages you are in constant fear of drifting – even putting down an anchor you need a huge amount of space around you.

“So then you anchor further out into the slop and the big waves, so the owners find it difficult to get on and off the boat, and suddenly other problems can overwhelm the project,” Doyle points out. One increasingly popular solution to that particular problem is a luxury landing craft.

Too big for the Panama Canal

It might seem counter-intuitive, but it is Aquijo ’s owner’s focus on the sailing experience that has enabled the designers of the 86m ketch to push the size limits of a traditionally rigged yacht.

“ Aquijo is a sophisticated machine and brings most aspects of a 1,600GT motor yacht with her,” comments designer Bill Tripp. “But she does not aspire to helicopters or submarines, the feeling of the boat is one of use. She is for getting out there, and for going out sailing. In Greece this summer, she would go out for an afternoon of sailing in 35 knot Meltemi because it is so much fun to sail at 20 knots, as if on rails.

“We have always done sailboats that can get under the Panama Canal bridge, and the biggest we were happy to do and put under the bridge was really 46m because after that we didn’t have big enough sails for the boat.

“Then five years ago we launched A Better Place , and the owner said ‘I’ll go around, I don’t want to limit my boat because of the bridges.’ With Aquijo they said, we want to go to these places anyway, so let’s get the best sailboat we can. So suddenly, instead of having this 63m limit on the rig, that all opened up and we could start doing a sailing boat that had a gross tonnage like some of the bigger motoryachts.

“I think we’re going to see more of that. You can look at the Strait of Magellan [an alternative route to rounding Cape Horn ], as a place that’s a really long way away or a place you really want to go.”

The wish list

Russian billionaire Andrey Melnichenko is keeping his Sailing Yacht A tightly wrapped under non-disclosure agreements, but a few intriguing details have been released, including magnifying windows which appear larger inside than outside, and a gimballed crow’s nest, accessible by lift, 60m high in the curved mast.

An observation pod embedded in the keel with foot-thick glass gives a mesmerising – and frankly terrifying-sounding – view of the propellers, and there’s a three-man submarine.

Gigayacht designers have come up with some imaginative solutions to meet owners’ foibles and demands. Drawings for the 101m sloop incorporated an entirely retractable hardtop to the flybridge to give the owner his requested uninterrupted view of the sails and sky.

Plans for the Japanese-influenced Komorebi design feature a live tree on the aft deck. Watersports toys are old news – now tender garages are specified to house motorbikes, amphibious quad bikes, even custom-built marinised supercars.

On Aquijo , the headline feature is the ‘beach club’ on the lower deck. “For a sailing boat it is a huge area, they have a sauna, hamman [Turkish Bath], a rainfall shower, a relaxing area, this huge whirlpool in the middle, a little pantry, and enough space for gym equipment around the pool,” explains interior designer Robert Voges.

Beach club on Aquijo.

Voges says the trickiest element on the yacht was the flawless high shine steel mast claddings which run through the interior. “It is like a piece of art. The mast was going through the main saloon and guest corridor, and we didn’t want to hide it. So we decided to make a feature out of it with seamless stainless steel cladding with integrated LED strip lights from top to bottom over two decks.”

One of the most radical projects in progress is the 141m Dream Symphony , a four-masted design currently in build in Turkey. Originally slated for launch this year, the project is progressing slowly – in part due to the fact the yacht is constructed of wood. Her design includes a large aft deck swimming pool that transforms into a raised helipad area.

This is the type of concept which seemed fantastical just a few years ago, but is now reality in the motoryachts world where designs like the 81m Alfa Nero have deployed it successfully.

“It’s a good solution because you usually have to drop down all the stanchions and any elements that are higher than the helipad itself, whereas if you lift the helipad you don’t have to lower the other elements,” explains Dream Symphony designer Ken Freivokh.

The 141m four-masted Dream Symphony

“The brief did not call for a resident helicopter that would have its own hanger – it’s just a ‘touch and go’. You don’t want to set aside space for a helicopter permanently that’s almost never there, so if you have a reasonably sized swimming pool why not use the base of a pool to just receive the helicopter, and then once the helicopter flies away you can put it back to normal operations?” Why not indeed?

No matter how grandiose your ideas, however, not even the vast volumes of a gigayacht can be entirely filled with art galleries and Reiki studios. Robert Voges explains that, like any other ship, “We have to start with all the emergency exits, the corridors, staircases . . . and from there we can work with the other areas which are left over.”

Ken Freivokh estimates that at least 20 per cent of the interior space has to be allocated to the back-of-house systems required to maintain the equivalent of a small hotel – air conditioning, waste, media, and other unglamorous elements behind the touch-screen luxury.

Edge of reason

At 12,700 GT, Sailing Yacht A has the vastest volume of all. But can she be called a sailing yacht? She carries three of the world’s largest carbon rigs – curved, unstayed, capable of rotating a maximum of 70 degrees – featuring in-boom furling that can deploy 3,747 square metres of sail area (67 per cent more than Maltese Falcon ) from a finger tip command. And yet she cannot help but look implausible.

The hull has a maximum beam of 24.8m and includes 24 shell doors.

No matter how innovative the technology on board, or how vast the expense, the elements will not bend to the will of man or millionaire. Various estimates have put her cost at $400-500million, or in the region of £320 to £400 million – to put those sort of figures in context, the bill for the London Olympics Aquatics centre came in at under £300m.

Sailing Yacht A will be ‘sail-assisted’, not wind-powered. Confounding, aggressive in her styling, she’s a yacht that has attracted scathing opinions as often as wide-eyed wonder. But what is the point of creating a gigayacht that doesn’t?

“It is a creative process with the owner,” comments Aquijo ’s designer Bill Tripp, “They have this idea that they can make something that speaks to them. They don’t write symphonies, and they’re not great painters or sculptors, but on the other hand money is vital energy, and they can create these things that wouldn’t exist otherwise.

“It’s great when someone says, ‘Life’s short, I’m just going to do this.’”

Despite the pandemic, the superyacht world continues to welcome new entries. These are the world’s biggest yachts by length.

Even in a pandemic, the size of the global superyacht fleet keeps on growing. The top 25 largest yachts in the world now total a combined 11,849 feet, with the smallest yacht on the list,  Maryah , measuring a whopping 410 feet. Built by shipyards all over the world—from the Netherlands to the United Arab Emirates, Italy, Turkey, Greece and the United Kingdom, to name just a few—new launches and refits are delivered each year. The 2021 newcomers hail from Lürssen, Dream Ship Victory and Lloyd Werft. With many new gigayacht builds in the pipeline, the list will be much more competitive in the coming years. Here are the world’s top 25 yachts by size, from  Maryah  to  Azzam.

25. ‘Maryah’ (410 feet, 1 inch), Neorion

This former Russian research vessel was originally launched by the Szczecinska yard in Poland. In 2010, it underwent a five-year rebuild at the Elefsis yard in Greece. The stodgy research vessel that went in reappeared in 2014 as a thoroughly modern custom-built superyacht. The UK-based  H2 Yacht Design  did both the interior and exterior, incorporating all the luxuries one would expect in a yacht this size. The swimming pool, spa, contemporary decor (including custom furniture, signature joinery, and bespoke details like fixtures and lighting), and generous interior space turned the ugly duckling into a swan.  Maryah , which reaches a top speed of 18 knots powered by a twin azipods propulsion system, has accommodation for 54 guests.

24. ‘Octopus’ (414 feet), Lürssen

Lürssen’s  Octopus  Elizabeth Withe

Originally built by Lürssen for Microsoft cofounder Paul Allen, eight-decked  Octopus  is the world’s largest expedition yacht. Allen kept all the luxurious features of a superyacht, but wanted  Octopus  to be able to set anchor at the ends of the earth for exploration. The Lürssen, delivered in 2003, has storage for two helicopters, seven tenders, a large SUV and an internal dock that extends through the hull holding two submersibles. A glass-bottomed observation lounge makes for spectacular viewing when cruising. The yacht has been involved in multiple exploration discoveries, aided by its onboard dive centre and hyperbaric chamber. Espen Øino drew the exterior, including a full-sized basketball court on the aft deck, while Jonathan Quinn Barnett did the interior. The yacht underwent a refit in 2019. It reaches a top end of 20 knots.

23. ‘Al Mirqab’ (436 feet, 4 inches), Kusch Yachts

Launched in 2008,  Al Mirqab  was built for Qatar’s former prime minister under the supervision of  Kusch Yachts  in the  Peters Werft shipyard  in Wewelsfleth, Germany. The Tim Heywood exterior includes a long, navy-blue hull with a white superstructure. The yacht’s diesel-electric propulsion involves an azimuth pod drive and gives the 436.4-footer a top end of 21 knots. Its interior by Andrew Winch won several awards, with images showing Arabic-influenced motifs on the marble floors of large social areas. The yacht’s centerpiece is a stunning, complicated floating staircase encircled by custom-made glass panels.  Al Mirqab  has staterooms for 36, and crew quarters for 45.

22. ‘Serene’ (439 feet, 3 inches), Fincantieri

Serene  was  Fincantieri ’s launch into the superyacht segment, and what a debut it was. The largest yacht ever launched in Italy when it was delivered in 2011 (surpassed three years later by  Ocean Victory ), the Espen Øino seven-deck design features a long, sleek blue hull, crowned by a white superstructure. The somewhat racy curves serve as a nice counterpart to the more serious-looking sections of the yacht, which include cutouts along the main and upper decks to allow strong visibility from the saloon and staterooms. The curved balconies on three levels are a nice touch that work aesthetically—and practically for better views. The open stern area has a winter garden (enclosed glass house) that allows dining in all seasons.  Serene  also has two helipads and a hangar, a big swimming pool, and a tender garage large enough for a submarine. Pascale Reymond of Reymond Langton Design created the 43,056-square-foot interior for the Russian owner, though its details have remained closely guarded.

21. ‘Crescent’ (443 feet), Lürssen

Espen Øino’s dark hull and tiered superstructure was one of the most exciting launches of 2018. Custom-built Project Thunder, as it was called internally at Lürssen, features cut-outs along the hull sides that allow full ocean views from the saloon on the primary deck, as part of  Crescent ’s distinctive curved superstructure. Its most noteworthy feature is the jaw-dropping bank of three-deck-high windows in the center of the yacht. This architectural feature serves as the centerpiece of a very compelling design. The yacht has accommodations for 18 guests in nine staterooms. Little is known about the François Zuretti-designed interior, other than Lürssen describes it as being “traditionally styled.” If it lives up to  Crescent ’s brash exterior, the complete yacht promises to be an entirely groundbreaking design.

20. ‘Savarona’ (446 feet, 2 inches), Blohm+Voss

Blohm+Voss’s  Savarona  

Launched in 1931,  Savarona  was built for American heiress Emily Roebling Cadwallader. The yacht was eventually acquired by Turkey to be the presidential yacht of Kemal Atatürk, founder of modern Turkey.  Jane’s Fighting Ships  described the yacht in 1949 as “probably the most sumptuously fitted yacht afloat.”  Savarona  was later converted to a training ship for the Turkish Navy and, in 1978, destroyed by fire. The yacht laid in tatters for 10 years. A Turkish businessman spent around $45 million refurbishing  Savarona , commissioning Donald Starkey for the interior and replacing the original steam-turbine engines with modern Caterpillar diesels. The yacht’s interior was refitted again in 2013, once again becoming the official presidential yacht in 2014.  Savarona  features a swimming pool, Turkish bath, 280-foot grand staircase, a movie theater, and a library dedicated to Atatürk.

19: ‘Flying Fox’ (446 feet, 2 inches), Lürssen

Delivered jointly by Imperial and Lürssen in 2019, 446.2-foot  Flying Fox  is the largest yacht available on the charter market. Key features of the Espen Øino-designed exterior are a curvaceous dove-gray hull and a 3.7-foot swimming pool that runs athwartship on the main aft deck, the largest ever found on board a yacht. A two-decked spa also gives guests access to a cryosauna, hammam and relaxation room with a fold-down balcony at sea level. Packed to the rafters with the latest amenities, the yacht holds a diving center, decompression chamber and two helipads.  Flying Fox  is PYC compliant and can accommodate 25 guests.

18. ‘Rising Sun’ (454 feet, 1 inch), Lürssen

Designed by the original guru of yacht designers, Jon Bannenberg,  Rising Sun  was built by Lürssen for Oracle CEO Larry Ellison, and is currently owned by billionaire David Geffen. The yacht was delivered in 2004 and last refitted in 2011. Defined by banks of windows across the superstructure,  Rising Sun  has 86,000 square feet of living space in 82 rooms. It can accommodate 18 guests in nine cabins, with the capacity to carry up to 46 crew. The interior by Seccombe Design includes a gym, cinema, and wine cellar. The rear cockpit deck was designed as a basketball court. Geffen received a global media backlash in 2020 for his “tone deaf” social media posts that pictured himself on board his yacht during Covid-19 lockdown.

17. ‘Al Salamah’ (456 feet), Lürssen

Lürssen’s  Al Salamah  Lürssen

When Lürssen launched  Al Salamah  in 1999, it was the third-largest yacht in the world. Its ranking at number 14 shows how much has changed in the last 20 years. Code-named MIPOS, or Mission Possible, the yacht was designed by  Terence Disdale . The large imposing exterior is primarily protected space, with an upper deck exposed to the elements.  Al Salamah  has staterooms for 40 guests, including two owner suites, 11 VIP staterooms, and eight twin cabins. The yacht can carry up to 96 crew and has a top speed of 22 knots.  Al Salamah  was last refitted in 2009.

16. ‘Scheherazade’ (459 feet, 3 inches), Lürssen

The owner of 459.3-feet Lürssen-built  Scheherazade  (formerly known as Project Lightning) finally took delivery of the mega yacht in June 2020 after it was pictured during sea trials in November 2019. What can so far be deciphered from available photography includes two helipads, forward and aft, and a large beach club aft, as well as a reported seven-foot beam. Very few details have yet been released of the highly private vessel, including even the names of designers or naval architects involved with the build.

15: ‘Ocean Victory’ (459 feet, 3 inches), Fincantieri

The largest motoryacht ever built in Italy, Fincantieri’s  Ocean Victory  was delivered to its owner in 2014. The seven-deck exterior by Espen Øino includes two helideck platforms and a hangar belowdecks, as well as exceptional outdoor social areas, and a floodable tender dock.  Ocean Victory  has accommodations for 28 guests as well as quarters for 56 crew.  Ocean Victory  also has six pools, a 3,300-square-foot spa, and an underwater observation room. The interior by Alberto Pinto remains a secret.

14: ‘Solaris’ (459 feet, 3 inches), Lloyd Werft

The 476-foot  Solaris  is one of the largest yachts to deliver in 2021, and yet still little is known about it. The highly private, vast explorer is built by German shipyard Lloyd Werft and undertook sea trials in the North Sea. The eight-deck exterior is by Australian designer Marc Newson and features a displacement steel hull with bulbous bow and steel superstructure with teak decks. Reportedly owned by Roman Abramovich, it houses a large helipad, sun deck and spacious beach club aft. Lloyd Werft built the Russian billionaire’s previous explorer yacht  Luna , which he reportedly sold for $360 million to his close friend Farkhad Akhmedov in 2014.

13. ‘Yas’ (462 feet, 6 inches), Abu Dhabi Mar

As a converted yacht,  Yas  is one of the most interesting vessels on this list. The dolphin-like exterior was originally a former Dutch Navy frigate that launched in 1978 and eventually sold to the navy of the United Arab Emirates, where it was renamed  Al Emirat . The yacht underwent its dramatic conversion in a facility in Abu Dhabi’s main port, emerging as a gleaming superyacht in 2011, with one of the most interesting profiles on the water. It was eventually delivered four years later. The design by the Paris-based Pierrejean Vision, defined by massive glass surfaces, can accommodate 60 guests and 58 crew members. Mated to a steel hull, the superstructure is the largest composite edifice ever built.  Yas  is capable of a 26-knot top speed and was last refitted in 2019.

12. ‘Dream Symphony’ (462 feet, 6 inches), Dream Ship Victory

Dream Symphony  by Dream Ship Victory Courtesy Dream Ship Victory

Sailing yacht  Dream Symphony  is a magnificent 462.7-foot schooner built by the Turkish shipyard Dream Ship Victory. When delivered in 2021, she will become the largest private sailing yacht in the world, knocking current largest sailing yacht,  Black Pearl , off the podium. Featuring naval architecture by Dykstra Naval Architects and an exterior and interior by Ken Freivokh, she reunites the same team who were behind the legendary  Maltese Falcon ’s ground-breaking Falcon dynarig.  Dream  Symphony’s hull is being built in wood – glued and laminated using the latest epoxy and composite techniques. Wood, carbon and stainless-steel run throughout the contemporary interior, while the rig includes Hoyt booms for maximum control.  Dream Symphony  boasts a fully private owner’s duplex, with master suite, salon, and office at main deck level, and a further spa, gym and treatment rooms on the lower deck. A sheltered open deck between the owner’s facilities and the guest deck house can be closed off to bad weather, creating concealed channels for full protection. And when the sun is shining, a double-height glass swimming pool features a rising floor that can doubles up as a touch-and-go helipad or dancefloor.

11. ‘Nord’ (466 feet),  Lürssen

Lürssen’s  Nord  (Project Opus) Photo: SuperYacht Times/Youtube

Nord  (Project Opus) has been a long time coming. She was announced in 2015 but didn’t hit the water until November 2020 when she conducted sea trials in the Baltic Sea. The 466-foot yacht features interior design by Italian studio Nuvolari Lenard and is Lürssen’s first yacht launched from its newly upgraded floating shed at its facility in Vegasack. Boasting many top tier amenities, the yacht includes a sports and diving center on the lower deck, multiple tenders ranging in size up to 50-feet and a large swimming pool. The two helipads support the yacht’s long-range cruising capabilities for autonomous remote exploration and a retractable hangar means the helicopter can slide neatly into the superstructure for storage when not in use. A generous 20 staterooms accommodate 36 guests across six decks, while a sleek aft-sloping superstructure gives Nord an individual profile on the water.

10. ‘A’ (468 feet, 5 inches), Nobiskrug

Nobiskrug Sailing Yacht  A  Photo: Courtesy of Nobiskrug

Delivered in 2017, the futuristic look of sailing yacht  A  includes smooth, silver-metallic surfaces and windows that look nearly invisible, three composite masts that bend slightly, and a deck hidden by high bulwarks. The Philippe Starck-design is a wild fantasy yacht of the future. The 468-foot sailing yacht is a technical victory for German yard  Nobiskrug , which developed composite fashion plates to create the unusual shapes, without any compromises in strength or fluidity. It has the tallest freestanding composite masts on any sailing vessel, a hybrid diesel-electric propulsion system and state-of-the-art navigation systems. The boat also reportedly has an underwater viewing platform in the keel. “Sailing yacht  A  is undoubtedly one of the most visionary projects Nobiskrug has ever been involved in,” said Holger Kahl, the firm’s then managing director. Starck’s interior remains a secret. The yard reports the yacht has a top speed of 21 knots. She remains today the world’s largest sailing yacht three years after her launch.

9. ‘El Mahrousa’ (478 feet, 1 inch), Samuda Brothers

Egypt’s royal yacht,  El Mahrousa  Screengrab

El Mahrousa , which means “the protected” in Arabic, is currently Egypt’s presidential yacht, though the 478.1-footer has a separate history as that country’s royal yacht. The London-based Samuda Brothers began the build in 1863, and it was launched in 1865. It was originally built for the Ottoman governor of Egypt, Khedive Ismail, and later carried three Egyptian kings into exile. The yacht was also at the opening of the Suez Canal in 1869. The world’s oldest superyacht features external design by the British naval architect Sir Oliver Lang, and has had multiple modifications over the years, including a lengthening by 40 feet in 1872 and another 17 feet in 1905. During the second refit, the owners replaced its paddle-wheel engines with turbine-driven propellers. The yacht, in care of the Egyptian Navy, occasionally goes to sea for a day or two. In 2015, it was used to inaugurate the new Suez Canal.

8. ‘Prince Abdulaziz’ (482 feet, 3 inches), Helsingør Værft

Helsingør Værft’s  Prince Abdulaziz  Photo: Shutterstock / Artesia Wells

This custom yacht, launched by Helsingør Værft in Denmark in 1984, was most recently refitted in 2005. The 5,200-tonne  Prince Abdulaziz  is one of the Saudi Royal family’s yachts, its first owner being King Fahd. Designed by Maierform, the yacht was the longest and tallest in the world at the time of its launch. At 482.3-feet,  Prince Abdulaziz  held the title for 22 years until  Dubai  launched in 2006. The late David Nightingale Hicks, known for his use of bright colors, was the interior designer. The lobby is said to be a replica of the  Titanic . Last refitted in 2005, it is rumored to be carrying surface-to-air missiles, though that may be an urban legend.

7. ‘A+’ (483 feet, 1 inch), Lürssen

Lürssen’s  A+  Photo: Klaus Jordan

Very little is known about  A+  (formerly  Topaz) , which was launched by Lürssen in 2012, other than it is the fourth-largest yacht ever built by the German shipyard. Tim Heywood Designs did the exterior, which features helipads on the foredeck and amidships on an upper deck. A lower aft deck includes a swimming pool. The German yard has not released any images of the Terence Disdale interior. Reported to be owned by Manchester City Football Club owner Sheikh Mansour bin Zayed al Nahnan – Emirati royalty and deputy prime minister of the UAE –  A+  has a top speed of 22 knots, and can carry 62 guests and up to 79 crew.

6. ‘Al Saïd’ (508 feet, 5 inches), Lürssen

Another 500-plus-foot yacht from Lürssen, the original Project Sunflower gained its official name of  Al Saïd  following its launch in 2016. Espen Øino’s exterior is akin to a classic cruise liner, complete with the twin exhaust stacks in the center of the superstructure. Owned by the Sultan of Oman, six-decked  Al Saïd  can carry 154 crew and, according to some sources, 70 guests. Lürssen says  Al Saïd  has a top speed of 22 knots. The London-based Redman Whiteley Dixon studio designed the interior, which includes a concert hall that can hold a 50-piece orchestra.

5. ‘Dilbar’ (511 feet, 8 inches), Lürssen

Lürssen’s  Dilbar  Photo: Josep Baresic

The 2016 launch of  Dilbar  gave Lürssen the distinction of not only building the longest yacht ever ( Azzam ), but also the largest in terms of volume. Espen Øino designed the exterior, creating a full-bodied superstructure of long, flowing decks, along with two helicopter pads.  Dilbar  also has an 82-foot swimming pool that can hold an incredible 6357-cubic-feet of water, and according to Lürssen, is the world’s longest on a yacht. The interior by Winch Design is defined by its “rare and exclusive luxury materials,” says the builder, declining to go into detail. Lürssen added that the world’s largest motor yacht was one of the most complex and challenging yachts ever built, because of its dimensions and technology. Despite  Dilbar ’s volume, the designers did a masterful job making the yacht look relatively svelte, with no obvious bulges along the length of the light ivory and bronze-accented hull. In June 2020, Dilbar returned to Lürssen for a significant refit, the details of which are yet to be revealed.

4. ‘Dubai’ (531 feet, 5 inches), Platinum Yachts

Sheikh Al Maktoum’s yacht,  Dubai  Bigstock

This Andrew Winch design was originally commissioned for Prince Jefri Bolkiah of Brunei as a joint project between Blohm+Voss and Lürssen, before it was halted in 1998 with just a bare hull and skeletal superstructure. The hull was sold to the government of Dubai, and, under the direction of the country’s ruler, Sheikh Mohammed bin Rashid Al Maktoum, work on the 531.5-footer began again, though this time by Platinum Yachts.  Dubai  delivered in 2006 and is now the sheikh’s royal yacht, with accommodations for 24 guests and quarters for 88 crew. The seven-decked yacht has an impressive 70-foot-wide atrium, landing pad for a Black Hawk helicopter, submarine garage, disco, and cinema. Full certification was obtained from Lloyd’s Register in October 2006, and it can reach a top speed of 26 knots.

3. ‘Eclipse’ (533 feet, 1 inch), Blohm+Voss

Stately  Eclipse , the 533.1-foot yacht delivered to billionaire Roman Abramovich, took five years to design and build. When it left the Blohm+Voss shipyard in Hamburg in 2010, it was the world’s largest yacht. The interior has 17 staterooms and a palatial master suite, with the capacity to carry 85 crew. Both the interior and exterior are designed by Terence Disdale. A proportional profile is defined by tiered decks that sweep upward and bend ever so slightly at the aft ends.  Eclipse  has a 185-foot-long owner’s deck and, at the time of its launch, the largest swimming pool on any superyacht (the bottom raises and converts to a dance floor). Other features reflecting its stature: the capacity to hold three helicopters, including one in its belowdecks hangar, a sophisticated stabilization system, six tenders, and an enormous spa, gym, and beach club. Hybrid diesel-electric engines are connected to Azipod drives that give  Eclipse  a top-end speed of 21 knots, with a range of 6,000 nautical miles.

Little information has ever been released about the world’s second-longest superyacht, custom-built  Fulk Al Salamah , and it has been shrouded in mystery since first announced in 2014. Even the overall length of 538.1 feet has been estimated from AIS data. However, built and delivered by Italian builder Mariotti Yachts in their Genoa shipyard in 2016, the imposing vessel is believed to be owned by the Omani royal family. Exterior design is by Studio de Jorio, and it is considered by some to resemble more of a support vessel than a superyacht. Nonetheless, aerial photography shows an impressively large helideck, raked masts and a bathing platform.

Lürssen’s  Azzam  Screengrab

It’s not surprising that the world’s longest yacht hails from a shipyard with 13 out of the 25 top builds in the superyacht arena. Unfortunately,  Lürssen  could never really boast about  Azzam  after its launch in 2013 because of the owner’s penchant for privacy. Mubarak Saad al Ahbabi directed a team of designers and engineers who started with the bare concept, worked through the technical challenges of what might be the most complex superyacht ever, and finished with an unusually large vessel that can top the 30-knot mark. Nauta Yacht’s exterior features a long, sleek forward area, with well-proportioned tiers moving up to the skydeck. Lürssen describes the interior by Christophe Leoni as “sophisticated, with luxurious decor inspired by the Empire style of the early 19th century.” Its gas turbines, connected to water jets, push  Azzam  to more than 30 knots, giving it the ability to operate at high speed in shallow waters. She also boasts an impressive build time for a yacht of her size, with construction taking only three years after one year of engineering.  Azzam  was last refit in 2020 at MB92 in Barcelona.

World's biggest yacht: 8 of the best features on board expedition superyacht REV Ocean

By Katia Damborsky |   22 August 2019 2021-06-22

With a core focus on marine research and conservation, the 183m/600ft motor yacht REV will have the ability to collect and generate energy from ocean plastics. She will become the world's largest yacht upon completion, and will be available for private yacht charters in some of the most remote regions on earth.

Currently in the final stages of construction, research expedition vessel REV (or REVOcean) is pioneering the latest in technological innovation to create a new generation of superyacht.  

She will be equipped with some of the most impressive on-board features ever seen on a yacht, including the ability to collect and generate energy from 5 tonnes of ocean plastics per day.

She will be used primarily as a research platform for studying the world’s oceans and finding solutions to problems including climate change, overfishing and plastic pollution.

REV has a gross tonnage of 17,440 tonnes and a length of 182.9m, or 600ft.

Currently the longest ever superyacht is 180.65m (592ft) superyacht AZZAM , while the largest yacht in terms of gross tonnage is 156m (511ft) superyacht DILBAR, with a volume of 15,917 gross tonnes.

REV knocks both of them out of the water, and will become both the largest and longest yacht in the world when she is delivered.

She has been commissioned by ocean research company Rosselinis Four-10, which is owned by Norwegian billionaire Kjell Inge Roekke.

Income for crewed yacht charters will go towards funding the yacht's future research operations. 

Take a look at all the highlights and special features on board yacht REV. 

State-of-the-art research facilities

REV will play host to six laboratories with multi-functional usage which includes dry, wet and chilled facilities for a range of different research purposes. 

She will also have a huge 7.7m x 5m Moon pool in her hull. This wide opening will provide direct access to the water below, allowing underwater vehicles to be lowered and raised with increased ease and flexibility. 

In total, around 4,000 square metres (the equivalent of 15 tennis courts) of on-board space is dedicated to research, which makes up around 40% of REV’s interior.

In summary:

• Six laboratories
• 7.7m x 5 Moon pool (opening in hull to allow submersibles to be launched and raised)
• On-board research space equates to 15 tennis courts

Live species harvesting

REV will use highly sophisticated technology to safely collect and winch live species of fish from around 3,000 metres below the sea’s surface.

The winches can maintain position and depth whatever the weather and sea conditions, making them reliable under any circumstances.

A live visual feed helps to identify the species, and the system can be adjusted to target a particular size of fish and release those that don’t match. They are transported on board REV through a pipe, and can then be released unharmed after being studied or tagged. 

REV will also feature drop keels fitted with sensitive hydrophones which will listen out for marine mammals.

She also has a dive centre with a decompression chamber, air and nitrox systems.

• Ability to collect live species from 3,000 metres below the sea
• Live visual feed allows those on board to identify the species
• Hydrophones listen out for marine mammals
• Dedicated dive centre

Underwater discovery

The yacht's hangar will house an impressive range of vehicles and accessories. These include remotely-operated water vehicles capable of descending to depths of 6,000m (almost 4 miles) with the help of a cord connected to REV. 

REV will also have a fully autonomous underwater vehicles, which use sonar to scan the seafloor and pinpoint a predefined mark. These can be extremely helpful when finding shipwrecks or other irregularities on the seabed.

She will have a submarine and dedicated equipment to measure CTD (conductivity, temperature, and depth).

• Autonomous and remotely-operated submersibles.

Two helipads

REV has two helipads for drones and helicopter surveys. One is located on the aft deck and the second is on the foredeck. 

They will make it even easier to access and disembark the yacht, particularly when it comes to stepping on shore in high-latitude regions.

Dual helipads and helicopters are also essential for exploring Polar regions, creating a back-up should there be any kind of mechanical failure, giving REV full global access.

Superyacht styling

The yacht's exterior style is the work of world-renowned designer Espen Oeino. Designed to balance the functionality of a research vessel with the elegance of a superyacht, her profile is streamlined and well-proportioned

H2 Design is responsible for the yacht's interiors. Jonny Horsfield, head designer, has said that he is embracing the unique challenges associated with a project like this, and hopes to create a holistic and calming interior. 

In total, the yacht provides accommodation for 28 guests in 18 cabins with a complete crew of 54.

Auditorium and media editing suite

REV will boast an enormous auditorium with tiered seating to host up to 36 people. Fitted with an advanced sound system, the space will be perfect for lectures and knowledge-sharing events.

The yacht will also have a conference centre with two meeting rooms and a hot-swap desk arrangement which is designed to facilitate social interactions between research teams and other charter guests.

• 36-person auditorium
• Conference centre with two meeting rooms

Environmentally-friendly credentials

Environmental performance was a crucial component throughout the building of REV. She features the SeaQ Green Pilot, a fuel-optimising system that will allow the crew to reduce REV’s carbon footprint as much as possible.

She will also make use of a high-technology incinerator, which allows on-board waste and ocean plastics to be burnt in an environmentally-positive way with limited emissions.

 Every 10 kilograms of waste burned will generate 110kWh of thermal power, which is used to supply REV with hot water. She will also have a heat recovery system which will generate fresh water through an evaporation plant. 

Other key elements include an energy recovery rudder system, medium-speed engines, a direct drive diesel-electric propulsion system with batteries and an exhaust cleaning system.

• Ability to collect and generate energy from ocean plastic
• Fuel-optimisation system

Ocean-going capabilities

REV will be capable of complete autonomy at sea for up to 114 days, meaning she can be completely self-sufficient in terms of stock and fuel. 

VARD estimates that she will have a range of 21,120 nautical miles while cruising at 11 knots.

For any research-related charters, she can accommodate 30 crew and 60 research personnel.

This piece will be updated as REV nears completion and delivery.

The 25 Greatest Superyachts of the Past 100 Years

Yacht design and technology—from steam engines to hydrogen fuel cells—have changed dramatically over the last century. these 25 standout vessels have been at the forefront of that revolution., julia zaltzman, julia zaltzman's most recent stories.

A Century of Sea Change

Yachts have seen remarkable transformations in design and technology in the last 100 years. The lengths and shapes have changed decade by decade, from the mini-ocean liners of the 1920s to a more glamorous, fuller shape by the 1950s, eventually giving way to the layered wedding-cake construction that was so popular until about a decade ago. Now, just about anything goes, judging from the list below, with yachts boasting vertical bows being the most popular.

Technology also changed over the years, from steam engines to diesel to a growing list of hybrid diesel-electric powerplants. In the next five years, expect to see the first generation of superyachts with hydrogen- or methanol-powered fuel cells. What really hasn’t changed in the last century are owners’ desires to create superyachts that are unique, often clashing with the accepted design norms of the time.

Here are the 25 greatest superyachts from the last 100 years.

'Delphine' (257 Feet 9 Inches) 1923, U.S.A.

Delphine is the original 1920s oceangoing queen. American automobile magnate Horace Dodge commissioned the vessel, rumored to have once hosted former President Franklin D. Roosevelt and Winston Churchill, and Michigan shipbuilding company Great Lakes Engineering Works built it in 1921. At 258 feet, Delphine remains the largest yacht ever built in the U.S. that is still in operation. She is also the largest active steam-driven yacht in existence. The two original 1,500 hp steam engines were re-equipped with two modern water-tube boilers during a 2003 refit, which provide 18 metric tons of steam per hour. Surviving a stint in the U.S. Navy during World War II, several fires, and multiple owners, Delphine is today fully restored to her 1920s glory, including original teak on the main deck and a revived Tiffany-designed interior.

'Talitha' (247 Feet) 1929, Germany

Talitha is one of the world’s first superyachts with an exceptional pedigree. F. Krupp built the vessel, which was originally penned by naval architects Cox & Stevens (leading designers of their day), in Kiel, Germany. First known as Reveler , Talitha was delivered in 1929 to Russell Algar, chairman of the Packard Car Company. A string of high-profile owners ensued, including John Paul Getty Jr. in the 1930s, son of one of the richest men in the world at the time. Getty commissioned an exterior and interior redesign by late superyacht designer Jon Bannenberg and, in 1993, a full reconstruction was completed at the Devonport shipyard in Plymouth, U.K. Regular refits since, including a 1999 newly installed wheelhouse, has made Talitha successful as a popular charter yacht.

' Malahne' (164 feet) 1937/2015, UK

Originally designed and built for the owner of renowned J-Class yacht Velsheda , classic motor yacht  Malahne enjoys a period interior designed by Scottish designer Guy Oliver (best known for styling London’s 10 Downing Street and Claridge’s). Original Art Deco features include Baccarat crystal, Willer porcelain, Georg Jensen silverware, and a lamp by 1930s designer Edgar Brandt. The yacht was once used as the production headquarters for Lawrence of Arabia and had luminaries such as Elizabeth Taylor, Grace Kelly, and Frank Sinatra walking the teak decks. In 2015, it underwent an extensive restoration at British shipyard Pendennis, which focused on maintaining its old-world glamour, including the yacht’s 25-foot custom-built Cockwells varnished Brazilian mahogany high-speed tender.

'Savarona' (446 Feet 9 Inches) 1931, Germany

Launched in 1931, Savarona was built for an heiress, enjoyed by royalty, and starred on the big screen. Built by Blohm & Voss for Emily Roebling Cadwalader, granddaughter of Brooklyn Bridge engineer John Roebling, 446-foot Savarona was featured in the German science-fiction film Gold . The Turkish government bought the vessel in 1938 and leased to Turkish businessman Kahraman Sadıkoğlu in 1989, who spent $45 million refurbishing the yacht. The original steam turbine engines were replaced with modern Caterpillar diesels, but the original 282-foot gold-trimmed staircase remains. Today, Savarona is the official presidential yacht of the Republic of Turkey.

'Shemara' (212 Feet, 2 Inches) 1938, Great Britain

Within a year of being built in 1938, 212-foot Shemara was requisitioned by the Royal Navy and used throughout World War II as a training vessel for anti-submarine warfare. Following the end of its service, the superyacht returned to her owner Bernard Docker, who entertained high society aboard its decks. Later in life, Shemara endured long periods of neglect until current owner Charles Dunstone acquired her in 2010, starting the long road back to refurbishment. Alongside much of the original teak and steel exterior features, Shemara is now fitted with a Rolls-Royce diesel-electric system, including two electrically driven azimuthing pods and a bow thruster.

'Christina O' (325 Feet) 1943/1954

Possibly one of the most eminent superyachts of all time, 325-foot Christina O didn’t begin life in the spotlight. Built in 1943 by Canadian Vickers, the vessel served as a frigate in World War II until 1954 when Greek shipping magnate Aristotle Onassis bought it as war surplus for a mere $34,000. He spent $4 million on the refurbishment and then entertained the world’s elite on board, from Maria Callas and Grace Kelly to Jack and Jackie Kennedy, prior to Onassis marrying Jackie. Named after Aristotle’s daughter, Christina O enjoys a bronze-edged swimming pool with a mosaic dance floor that rises at the push of a button. The stools in Ari’s Bar retain the original leather upholstery.

'V2V' (ex-Carinthia VI) (137 feet, 7 inches) 1973, Germany

The first major yacht designed by Jon Bannenberg and a breakthrough build for German shipyard Lürssen, Carinthia VI is a star of the decades, commissioned by supermarket magnate Helmut Horten as the sixth yacht in his Carinthia fleet. However, Carinthia V was in fact the original version but sadly hit an uncharted rock on her maiden cruise in the Mediterranean and sank. Horten ordered an almost identical replacement (this time with extra watertight bulkheads) and used Carinthia VI until his death in 1987. In 2016, the yacht suffered severe damage in a fire. Its new owner then bought the yacht, undergoing an extensive rebuild in Turkey to its original Bannenberg lines that was completed in 2023 when the yacht was renamed V2V.

'La Sultana' (214 Feet 56 Inches) 1962, Bulgaria

A Bulgarian passenger ferry turned Soviet spy vessel, 214.5-foot La Sultana has a checkered past. Built in 1962 for operations in the Black Sea, it was absorbed into the Russian fleet during the Cold War and sent to the North Atlantic for unofficial reconnaissance on the United States and United Kingdom. In 2015, La Sultana  completed a seven-year refit, which saw the addition of a raised bow, seven guest cabins across six decks, and a diesel engine installed to drive the original propeller. Several spying instruments were also discovered, including a radioactivity detector and thick aluminum insulation across the entire boat. The original push button steering controls are still in operation.

'Highlander' (164 Feet) 1986, Netherlands

American media mogul Malcolm Forbes commissioned the 164-foot Highlander , built by Feadship to a Jon Bannenberg design with De Voogt naval architecture, in 1986. The yacht’s historic guest list reads like a who’s who of Hollywood stars, from Elizabeth Taylor to Robert De Niro. Two bathrooms in the master suite are offset by six guest cabins. Those lucky enough to charter this piece of yachting history also have use of Forbes’s original cigarette boat, now re-painted in jet black with a bold red stripe.

'Tatoosh' (303 feet) 2000, Germany

Built by Nobiskrug for cellular pioneer Craig McCaw, the 303-foot Tatoosh was more famously owned by the late Microsoft cofounder Paul Allen, who bought the yacht off McCaw in 2001. Penned by German designer Claus Kusch—with input over the years from Jon Bannenberg, Terence Disdale, Martin Francis, and Stefano Pastrovich— Tatoosh is arguably one of the foremost explorer yachts of the modern age. The vessel was conceived to be a world cruiser with all the toys and entertainment that a yacht could carry. Alongside two helicopter landing pads, it has 11 staterooms for 19 guests, a heated swimming pool with a lifting floor, a cinema, and a dive center with a nitrox refilling station for deeper dives.

'Al Salamah' (456 Feet 10 Inches) 1999, Germany

At the time of its construction in 1999, 456-foot Al Salamah was the third largest yacht in the world. The build began at German yard HDW in Kiel but was completed by Lürssen in Bremen, the only yacht builder at the time capable of meeting the owner’s demanding timeline. Al Salamah was commissioned by the late Saudi Arabian crown prince Prince Sultan bin Abdul Aziz. Estimated to be worth in the region of $200 million and accommodating 36 guests, the ample amenities include a cinema, a fully equipped onboard hospital, two full-time beauticians, a business center, and a spa.

'H' (ex-NEOM) (311 feet) 2000, Netherlands

Delivered in 2000, the 311-foot  H   remained the largest Oceanco yet built and the largest yacht built in Holland until the delivery of Kaos (ex- Jubilee ) in 2017. Originally named Al Mirqab , the vessel was a highly private yacht under the ownership of the Qatar royal family before ex-politician and co-owner of Formula One Force India team Vijay Vittal Mallya took ownership in 2006. The Maltese government seized the lavishly outfitted yacht, which includes a helipad large enough for a twin-engine helicopter, Elton John’s baby grand piano, a full medical suite, and triple engines each delivering 10,000 hp, in 2017 over unpaid maritime bills. NEOM was auctioned off to her current owner in 2018.

'Rising Sun' (453 Feet) 2004, Germany

Built for Oracle cofounder Larry Ellison in 2004 and currently owned by business mogul David Geffen, Lürssen’s Rising Sun is another Jon Bannenberg success story, completed two years after the designer’s death. Even with her 453-foot length and 7,841-gross tonnes volume, Rising Sun achieves an impressive top speed of 28 knots. The owners were impressed enough with the speed to build a suspended, tube-like walkway so visitors can see the four MTU 20V 8000 M90 diesel engines providing the power. A bank of full-height curved windows run along the entire length of the superstructure, flooding the interior with natural light and giving the yacht a striking exterior profile.

'Motor Yacht A' (390 feet, 4 inches) 2008, Germany

Few yachts divide opinion like M/Y A . Designed by Philippe Starck, engineered by naval architect Martin Francis, and built by Blohm + Voss, the yacht is rumored to have cost in the region of $300 million to bring to life. Characterized by its head-turning reverse bow and vertical superstructure, the vessel is a private floating fortress where guests’ access to the water is restricted to the stern. It boasts a cathedral-like tender garage and three swimming pools; it’s also the predecessor to the even more controversial S/Y A , which emerged nine years later and briefly held the place of world’s largest sailing yacht before being displaced by Koru.

'Dubai' (531 Feet 5 Inches) 2006, Germany

Prince Jefri Bolkiah of Brunei first commissioned Dubai in 1995 to be built in collaboration by German shipyards Blohm + Voss and Lürssen. But the superyacht was not completed until 2001 by Platinum Yachts when current owner, Sheikh Mohammed bin Rashid Al Maktoum, took over the project. British studio Winch Design crafted the exterior, and the vessel is reported to have cost in the region of $400 million to build. Dubai  was the largest yacht in the world until 2010, when she was replaced by Roman Abramovich’s 533-foot Eclipse . Dubai ’s amenities, spread across eight decks, include a helipad, two 33-foot chase boats, a squash court, and 20 Jet Skis.

'Savannah' (273 feet, 11 inches) 2015, Netherlands

Savannah is renowned for being the first hybrid yacht on water, with fuel savings of up to 30 percent. It blends a single diesel engine with three gensets, batteries, a propeller, and an azimuting pioneering electro-mechanical propulsion platform. Built by Feadship, the yacht’s 41-foot beam was such a tight fit for the Dutch canals during delivery that the builder wrapped her in protective film and used plywood on the sides to serve as fenders. With its interior and exterior designed by Cristina Gherardi Benardeau, the yacht was also ahead of its time, with a corridor of double-height video walls, a floating superstructure, and an underwater Nemo lounge.

'Maltese Falcon' (289 Feet) 2006, Turkey

The legendary Maltese Falcon broke the mold of yacht design when launched in 2006. Perini Navi’s 289-foot, three-masted schooner was the result of its adventurous owner, the late Tom Perkins, and naval architect Gerard Dykstra’s radical design idea. The show-stopping Dynarig concept, now coined the Falcon Rig, catapulted Maltese Falcon to becoming the world’s most instantly recognized yacht, not to mention one of the most complex and largest sailing vessels ever built. The contemporary, computer-controlled sail system is based on freestanding carbon masts and yard-arms into which the sails furl. This system allows for easy sailing in all sea conditions. Famous charterers include Tom Hanks, Hugh Jackman, and Google cofounder Larry Page.

'Eclipse' (533 Feet) 2009, Germany

Aside from stealing the title of world’s largest yacht from 531-foot Dubai by a mere 1.5 feet, Eclipse is an exercise in amenities. Delivered to her owner Roman Abramovich in 2009, the vessel features a 52-foot swimming pool within an extensive beach club, two helipads, and a helicopter hangar under the foredeck. The 533-foot yacht is powered by a diesel-electric system driving azimuthing pods, one of the first of its kind. Eclipse retained the title of world’s largest yacht until the arrival of 590.5-foot Azzam in 2013. Designed inside and out by Terence Disdale, Eclipse took five years to build and is reported to have cost in the region of $590 million.

'Chopi Chopi' (262 Feet) 2013, Italy

Tasked with an experienced owner’s brief for a private yacht on which to spend long family holidays, CRN delivered with  Chopi Chopi . The largest yacht built by CRN at the time of her 2013 launch, the 262-foot Chopi Chopi remains the Italian yard’s flagship. A 656-square-foot owner’s suite with private terrace is complemented by a helipad capable of landing a three-ton helicopter. The interior ceiling heights are in excess of seven feet. But the focus of the design is on comfortable outdoor living, realized by a large beach club with an adjoining sauna, hammam, and spa with a treatment room.

'Azzam' (590 Feet) 2013, Germany

At a whopping 590-foot, Azzam has held the title of world’s largest yacht since her launch in 2013. Azzam was built by German yard Lürssen in a record three years for Sheikh Khalifa bin Zayed bin Sultan Al Nahyan, the current President of the United Arab Emirates. Alongside a 95-foot main saloon, Azzam carries a submarine and its own missile defense system. Two gas turbines and two diesel engines propel the yacht through the water more than 32 knots.

'Black Pearl' (350 Feet) 2018, Netherlands

Delivered by Oceanco in 2018, the 350-foot Black Pearl is only the second yacht in the world to be fitted with Dykstra’s DynaRig carbon masts and sailing system. Its eye-catching black sails span 9,514 square feet and can be set in a record seven minutes with the push of a button. The hybrid propulsion system combines wind power with two electric propulsion motors, and its controllable pitch propellers generate enough energy to support the yacht’s hotel load. A waste heat-recovery system is just one of the onboard features that helps to realize the owner’s vision of a “zero-impact” yacht.

'Excellence' (262 Feet) 2019, Germany

Built for an experienced serial owner, American automobile magnate Herb Chambers, the Winch-designed 262-foot Excellence was delivered in 2019. The vessel takes its design inspiration from Motor Yacht A , which Chambers at first didn’t care for but then began to love. The piercing reverse bow (that mimics the beak of an American eagle) and triple-height glass-fronted atrium give it curb appeal but has also led to the yacht being likened to a spaceship. Driven by the desire to have a connection to the outdoors, the design rests upon a symbiotic relation between the indoors and out and was ultimately successful, partially due to the use hundreds of square feet of curved, mirrored glass panels.

'Koru' (417 feet) 2023, Netherlands

Oceanco’s 417-foot Koru , commissioned by Jeff Bezos, is a three-masted, black-hulled schooner with a bowsprit, classic lines, and white superstructure. Reportedly costing $450 million to build and accompanied by a 246-foot custom Damen support yacht  Wingman , the new vessel is the world’s largest sailing yacht (knocking S/Y A off the top spot). Koru also holds the title of the largest superyacht ever built in the Netherlands and the tallest sailing yacht in the world, with masts that measure over 230 feet.

'Obsidian' (417 feet) 2023, Netherlands

Feadship’s 2023 delivery Obsidian has the appearance of a spaceship. But the boat’s technically advanced propulsion package, described as having a 90 percent reduction in total CO2 emissions, is what places it on this list, carrying the Dutch builder one step closer to its goal of achieving a zero-emission superyacht by 2030. The hybrid diesel-electric system is designed into a single-floor engine room creating additional interior space for owners, guests, and crew. With no drive shafts or rudders, the steering is done through a pair of electric Veth contrarotating thrusters. The diesel generators will also run on HVO, a second-generation biodiesel that manufacturers describe as a net-zero CO2 fuel. A low profile, horizontal styling features, and clean exterior shapes are a preamble for the yacht’s interior, which includes an underwater observation area—known as the Aqua Lounge.

'Luminance' (417 feet) 2023, Germany

Delivered in late 2023, Lürssen’s eighth largest build, Luminance , ranks as the 12th largest yacht in the world and is the 30th yacht built by the German shipyard with an exterior design by Espen Øino. The six-deck behemoth is one of the most significant yachts to be launched this year, with an internal volume of 9,000 GT, a beam of 66 feet, and an interior by Francois Zuretti. The gigayacht features two helipads, two Jacuzzis, a large swimming pool, and a distinctive stretched bow.
