The world’s most expensive yachts are floating private resorts built on a scale that few luxury properties can match. Some stretch well beyond 150 metres and combine swimming pools, cinemas, spas, helicopter facilities and enormous private suites with sophisticated marine engineering.
Their prices can exceed half a billion dollars because these vessels are individually designed, take years to construct and require thousands of skilled workers. German shipyard Lürssen appears repeatedly in this ranking because it has built many of the world’s largest and most ambitious private yachts.
Exact prices are rarely disclosed by owners or shipyards, so the figures below are widely reported valuations or reported transaction values rather than official retail prices.
1. Dilbar – Around $800 Million
Dilbar is widely valued at approximately $800 million, placing it among the most expensive private yachts ever built.
Delivered by German shipyard Lürssen in 2016, the yacht measures about 156 metres and is particularly remarkable for its enormous internal volume. At around 15,900 gross tonnes, it has been described as the world’s largest motor yacht by gross tonnage.
One of Dilbar’s signature features is its extraordinary swimming pool, believed to be one of the largest ever installed on a yacht. The vessel also incorporates huge entertaining areas, luxury guest accommodation and highly sophisticated engineering.
Its enormous dimensions, complex systems and custom construction explain its extraordinary value. Building a yacht at this scale requires far more than luxury decoration; it effectively involves creating a small private ship to superyacht standards.
2. Breakthrough – Around $793 Million
Breakthrough is one of the newest yachts to enter the very top end of the global market, with its reported value placed at approximately $793 million.
Built by Dutch shipyard Feadship, the 118.8-metre yacht gained international attention for becoming the first superyacht designed to use liquid-hydrogen fuel cells as part of its propulsion and hotel-power system.
Its interior is equally ambitious. Breakthrough includes an underwater viewing lounge, expansive guest accommodation, a large swimming pool and carefully separated circulation routes for guests, owners and crew.
The yacht was named Motor Yacht of the Year at the 2026 World Superyacht Awards. Its reported price reflects not only its luxury but also the enormous investment required to pioneer technology that has rarely been attempted on a private yacht of this size.
3. Eclipse – Around $700 Million
At approximately 162.5 metres, Eclipse remains one of the most famous superyachts ever constructed.
Built by Blohm+Voss and delivered in 2010, the yacht has been widely valued at around $700 million, although different estimates have circulated since its launch.
Eclipse contains an extraordinary collection of facilities. Reported features include two helicopter landing areas, swimming pools, luxury guest suites, extensive entertainment spaces and a small submarine.
Its immense size also requires sophisticated security, navigation and marine systems. For several years after its launch, Eclipse held the title of the world’s longest private yacht and became one of the defining symbols of the modern megayacht era.
4. Azzam – Around $605 Million
Azzam changed the superyacht world when it was launched by Lürssen in 2013.
At approximately 180 metres long, it remains one of the longest private motor yachts ever built and has a widely reported value of around $605 million.
Despite its enormous dimensions, Azzam was designed to be unusually fast. Its propulsion system combines gas turbines and diesel engines to produce extraordinary power, reportedly allowing speeds of more than 30 knots.
French designer Christophe Leoni created its sophisticated interior, while exterior styling came from Nauta Design. The combination of enormous size, high speed and bespoke engineering makes Azzam far more technically demanding than most luxury yachts.
5. Blue – Around $600 Million
The 160-metre Blue is another giant from Lürssen and is valued at approximately $600 million.
Delivered in 2022, Blue was developed with a stronger emphasis on reducing environmental impact than many earlier megayachts. Its engineering incorporates diesel-electric technology and systems intended to improve efficiency.
The vessel’s enormous volume allows for extensive private and guest facilities, although many interior details have remained confidential.
What makes Blue especially expensive is the engineering required to operate such a large yacht while integrating increasingly sophisticated energy-management and emissions-reduction technologies. At this level, the price is driven as much by the invisible machinery below deck as by the luxurious spaces above it.
6. Solaris – Around $600 Million
Solaris is a distinctive 140-metre yacht reportedly worth approximately $600 million.
Built by Lloyd Werft in Germany and delivered in 2021, the yacht is instantly recognisable because of its unusual metallic exterior and large stacked decks.
Solaris uses an advanced propulsion arrangement and offers enormous volumes for private accommodation and entertainment. Its design incorporates large windows, open deck areas and extensive security and technical systems.
The yacht is unusual even among modern megayachts because of its combination of futuristic styling, complex engineering and exceptional scale. Constructing such a customised vessel requires years of specialist design and fabrication.
7. Sailing Yacht A – Around $578 Million
Few yachts in the world are as immediately recognisable as Sailing Yacht A.
Built by Nobiskrug in Germany and designed by Philippe Starck, the vessel measures approximately 143 metres and has been widely valued at around $578 million.
Its three enormous carbon-fibre masts dominate its appearance and rank among the tallest free-standing yacht masts ever created. Despite its name, the vessel combines sail power with highly sophisticated motor propulsion.
Inside are multiple decks of luxury spaces, pools and an underwater observation area incorporated into the hull. The technical challenge of combining huge sailing systems, complex rigging and megayacht-style accommodation is a major reason behind its immense price.
8. Serene – Around $550 Million
Built by Italian shipbuilder Fincantieri, Serene is a 134-metre superyacht with a reported value of approximately $550 million.
Delivered in 2011, it was one of the largest yachts ever constructed in Italy at the time. The vessel later attracted major attention when it was reportedly purchased by Saudi Crown Prince Mohammed bin Salman in 2015.
Serene offers the type of amenities expected aboard a floating private resort, including large swimming and relaxation areas, helicopter facilities and extensive accommodation.
It has also been reported to include an underwater viewing space and facilities associated with a private submarine. Its massive dimensions and high level of customisation make it one of Fincantieri’s most significant luxury-yacht projects.
9. A+ – Around $525 Million
Formerly known as Topaz, the 147-metre A+ was built by Lürssen and is widely valued at approximately $525 million.
The yacht was delivered in 2012 with exterior styling by Tim Heywood and an interior created by Terence Disdale Design, two names associated with many major superyacht projects.
Its enormous decks provide space for swimming pools, entertainment areas, helicopter facilities and luxurious accommodation for owners and guests.
A+ illustrates why large Lürssen yachts dominate the highest end of the market. At nearly 150 metres long, virtually every component—from propulsion machinery to air-conditioning, security and interior joinery—must be custom engineered for a single vessel.
10. Koru – Around $500 Million
Koru brought the traditional romance of sailing into the era of the half-billion-dollar superyacht.
Built by Dutch shipyard Oceanco and delivered in 2023, the vessel measures approximately 127 metres and is widely reported to be worth around $500 million.
Koru is recognised as the world’s largest sailing yacht by length. Its three towering masts and classic-inspired profile make it visually very different from the enormous motor yachts that dominate most of this ranking.
Because a yacht of this size cannot easily accommodate every aviation and recreational requirement, it operates alongside a separate support vessel capable of carrying additional equipment. Koru’s scale, custom engineering and enormous sailing rig make it one of the most ambitious private sailing vessels ever created.
What Makes the World’s Most Expensive Yachts So Costly?
The world’s most valuable yachts are expensive because they combine luxury construction with the engineering demands of commercial-scale ships.
Enormous size: Yachts exceeding 100 or 150 metres require huge quantities of steel, aluminium, machinery, wiring and specialist equipment.
Bespoke construction: Nearly every major component is created specifically for one owner rather than mass produced.
Advanced engineering: Hybrid propulsion, hydrogen fuel cells, stabilisation systems and sophisticated navigation equipment can add enormous development costs.
Luxury interiors: Rare woods, stone, custom furniture, artwork and handcrafted fittings can require years of specialist work.
Private facilities: Swimming pools, cinemas, spas, gyms, helicopter decks and underwater lounges turn yachts into floating luxury resorts.
Operating capability: These vessels need substantial fuel capacity, long-range systems and accommodation for large professional crews.
Final Word
The world’s most expensive yachts show how far private luxury can extend when conventional size and budget limits disappear.
From Dilbar’s extraordinary volume and Breakthrough’s hydrogen technology to the enormous sailing rig of Koru, these yachts combine shipbuilding, engineering and bespoke luxury on a scale achieved by very few objects in the world.
