Eclipse was once the largest private yacht ever built and remains one of the most recognisable vessels in the world. Superyacht Guide explores the design, construction, ownership and changing operational life of this landmark yacht.
Few yachts have entered public consciousness as completely as Eclipse. At 162.5 metres, she is not simply a very large private vessel, but one of the defining yachts of the modern superyacht era. Her size, secrecy, technical ambition and association with Russian businessman Roman Abramovich made her internationally recognisable even to people with little interest in yachting. When Blohm+Voss delivered her in December 2010, Eclipse became the largest private yacht in the world, retaining that distinction until the arrival of the 180-metre Azzam in 2013. The record eventually passed, but Eclipse did not become visually obsolete. More than 15 years after delivery, her long foredeck, stepped white superstructure and dark horizontal bands of glazing remain distinctive, balanced and immediately identifiable.
That longevity owes much to the fact that Eclipse was not designed simply to appear futuristic at the moment of delivery. Her architecture was based on proportion, circulation and the practical requirements of the owner rather than on decorative novelty. While many newer yachts have adopted aggressive reverse bows, sharply sculpted surfaces and increasingly complex profiles, Eclipse retains the appearance of a substantial ocean-going ship. She looks powerful without appearing theatrical and enormous without allowing her scale to become visually chaotic. Her design continues to work because its major elements were integrated into one coherent form rather than added as separate statements of luxury.
The exterior styling, general arrangement and interior design of Eclipse were created by the British studio Terence Disdale Design, while Blohm+Voss was responsible for the naval architecture, engineering and construction. Terence Disdale has often explained that his studio begins with the plan rather than the profile. The starting point is how the yacht must function: how guests and crew move through it, where the principal facilities are positioned, how privacy is maintained and how the technical requirements influence the final shape. In the case of Eclipse, the owner's brief demanded several unusually large features, including extensive helicopter capability, a major swimming pool and wide interior views through large windows and low exterior bulwarks.
These requirements gradually created the yacht's recognisable architecture. The enormous forward helicopter landing area required the superstructure to be moved significantly aft, producing the unusually long foredeck that dominates the yacht's profile. The large swimming pool on the aft deck required another substantial uninterrupted space, while the yacht's lifeboats and technical equipment had to be integrated without making the vessel appear heavy or commercial. Eclipse therefore became long because her functions demanded length. Her proportions were not created merely to break a record, and that helps explain why the yacht still appears composed despite her extraordinary dimensions.
The exterior design is defined by long horizontal lines, deep bands of glazing and a carefully stepped superstructure that reduces gradually as the decks rise. Eclipse has a steel hull, an aluminium superstructure, a beam of approximately 22.4 metres and an internal volume of about 13,564 gross tonnes. Those figures place her closer in scale to a small passenger ship than to a conventional private yacht, yet the exterior avoids the appearance of a floating hotel. The high hull sides and substantial freeboard give her authority, while rounded deck ends, carefully judged overhangs and the progressive reduction in upper-deck volume soften the overall form.
Her aviation facilities are central to the design rather than temporary additions. Eclipse has two helicopter landing areas and has been widely reported as having the ability to accommodate another helicopter within a hangar beneath the forward deck. The foredeck is proportioned so that the yacht appears balanced whether or not an aircraft is present. This is a subtle but important design achievement. On many vessels, a helicopter appears to have been placed on an existing deck. On Eclipse, the deck, surrounding superstructure and overall length were designed around aviation capability from the beginning.
Although Eclipse is one of the most famous yachts in the world, her interior has remained largely private. The limited information that has emerged suggests that the design was deliberately restrained rather than overtly ceremonial. Terence Disdale has described his preferred interior philosophy as “beach house, not penthouse”, meaning that even a yacht of exceptional scale should feel comfortable when the owner and guests are dressed informally and living by the sea. Eclipse was therefore not conceived as a floating palace dominated by gold, ornate decoration or constant reminders of cost.
Creating that apparent simplicity required highly complex craftsmanship. The interior reportedly combines limestone, fossilised wood, shell, bronze panels, mosaics, limed wenge, buffalo hide and dark timbers with silver worked into the grain. Many of the materials and finishes were developed specifically for the yacht. Because Eclipse was built to demanding safety and passenger-vessel standards, the designers also had to ensure that materials met strict fire-resistance requirements while still producing the atmosphere of a private residence.
The yacht's scale is most clearly revealed inside. Eclipse accommodates up to 36 guests in 18 suites and carries approximately 70 crew. Her owner's private deck is reported to extend for about 56 metres, creating what is effectively a substantial private residence within the larger yacht. The main saloon takes advantage of the vessel's exceptional beam, while wide limestone windowsills provide informal seating and allow the sea to remain visible through the extensive glazing. Low exterior bulwarks were incorporated so that the view would not be interrupted when guests were seated inside.
The large aft-deck swimming pool also demonstrates the practical sophistication of the design. Its floor can reportedly be raised until it becomes level with the surrounding deck, transforming the pool area into an expansive entertainment or dance space. This is characteristic of Eclipse: major facilities are designed to serve more than one purpose, allowing an enormous yacht to remain adaptable rather than simply large. Commissioned artworks positioned in the yacht's lobbies are also said to help guests identify their location as they move between nine decks, illustrating the architectural challenge of making a vessel of this volume feel understandable and personal.
Eclipse was constructed by Blohm+Voss, the historic German shipyard in Hamburg. The project required approximately four and a half to five years of design, development and construction. She was launched in 2009 and formally delivered on December 9, 2010. Blohm+Voss developed the naval architecture, structural engineering and machinery systems required to transform the Disdale design into an operating vessel of more than 13,500 gross tonnes.
The technical achievement was substantial. Eclipse uses diesel-electric propulsion and has a reported top speed of approximately 21 knots, an impressive figure for a yacht of her size and volume. Her range is generally reported at around 6,000 nautical miles, allowing genuine intercontinental operation rather than restricting her to seasonal coastal cruising. Her construction was closely supervised, with a significant engineering team representing the owner and yacht management interests reportedly present at the shipyard throughout the project.
When Eclipse was delivered, she received the 2011 World Superyacht Award for Motor Yacht of the Year. The recognition was not based solely on her record-breaking length. It reflected the successful integration of private accommodation, aviation facilities, passenger capacity, swimming pools, technical systems and ocean-going capability on a scale that had rarely been attempted. Eclipse demonstrated that a yacht of more than 160 metres could still have a coherent identity and operate as a private vessel rather than feeling like a converted cruise ship.
Eclipse is widely and consistently associated with Roman Abramovich, the Russian businessman and investor. International news organisations and leading yacht-industry publications have described him as the yacht's owner or beneficial owner. As is common with very large private yachts, the legal registration may involve corporate entities and holding structures, meaning that the registered ownership name may not be identical to the individual publicly associated with the vessel.
Abramovich built much of his fortune through oil, aluminium, steel, mining and investment interests during the period following the collapse of the Soviet Union. He acquired a controlling interest in the Russian oil company Sibneft and later sold his stake to Gazprom in a multi-billion-dollar transaction. His business interests also included major positions connected with aluminium, steel and mining companies, making him one of the best-known figures among the Russian businessmen who accumulated substantial industrial holdings during the 1990s and early 2000s.
His international public profile grew dramatically after he purchased Chelsea Football Club in 2003. During his ownership, the club entered the most successful period of its history, winning English league titles, domestic cups, European trophies and the FIFA Club World Cup. Abramovich's spending transformed Chelsea into one of the leading clubs in world football and helped alter the financial structure of the English game. He sold the club in 2022 after the United Kingdom and European Union imposed sanctions on him following Russia's invasion of Ukraine.
Those sanctions later became inseparable from the story of Eclipse. A yacht originally designed to represent global mobility and unrestricted private travel became increasingly associated with the legal and political restrictions placed on its reported owner.
The exact construction cost of Eclipse has never been publicly confirmed. Figures repeated in the press vary widely, and some reports confuse original build cost with insured value, replacement value or later market valuation. Documents reported by international media indicated that the yacht was insured for approximately €390 million in 2011. In 2022, Reuters reported estimates placing Eclipse at $600 million or more, while other publications have suggested values closer to $700 million.
The most defensible conclusion is that Eclipse represented an investment of several hundred million dollars and remains one of the most valuable private yachts ever constructed. Claims placing her cost far above those figures are difficult to verify and should be treated cautiously. A yacht of this complexity cannot be valued simply by length or gross tonnage. Her custom engineering, extensive interiors, aviation capability, pools, technical systems, works of art and continuing maintenance history all contribute to her value.
The purchase price is also only the beginning of the financial commitment. A 162.5-metre yacht requires a large permanent crew, engineering support, insurance, fuel, security, aviation services, classification, management, shipyard access and periodic major refits. Even when Eclipse is stationary, her generators, air-conditioning, electrical distribution, water systems, preservation equipment and security systems must continue to operate. The yacht is therefore not merely an object but a permanent maritime organisation requiring continuous technical and financial support.
Eclipse has attracted an extraordinary number of stories about her security and technical systems. Over the years, reports have referred to armoured areas, bullet-resistant windows, missile-warning equipment, anti-photography lasers, multiple helicopters and a private submarine. Some of these claims may be rooted in genuine capabilities, while others have been repeated so often that speculation has gradually been treated as fact.
The yacht's extensive helicopter facilities, swimming pools, large lifeboats, substantial security arrangements and reported submersible capability are consistent with what is known about the project. Other details remain unconfirmed. The secrecy surrounding the interior and onboard systems has allowed plausible technical information, exaggerated reporting and outright invention to merge.
Eclipse does not require myths to remain extraordinary. Her confirmed specifications already place her among the most complex private vessels ever built. She combines accommodation for 36 guests, approximately 70 crew, multiple helicopter facilities, a large pool, ocean-going range, high speed and an owner's area comparable in scale to a substantial land-based residence.
For much of her operational life, Eclipse followed the familiar seasonal movement of a globally cruising superyacht. She was regularly seen in the Mediterranean during the European summer and in the Caribbean during the northern winter. St Barts became particularly associated with the yacht, especially during the Christmas and New Year period, when some of the world's largest yachts gather around Gustavia. Eclipse was also photographed in the South of France, Sardinia, Gibraltar, Florida and other established yachting centres.
Her range allowed her to travel between these regions under her own power, and her size did not prevent her from participating in the traditional Caribbean–Mediterranean cycle. She was built to move rather than remain permanently attached to one marina or coast. The yacht's aviation capability, large stores, extensive crew accommodation and long-range machinery were all suited to international operation.
That pattern changed significantly in 2022. Following the imposition of sanctions on Abramovich by the United Kingdom and European Union, Eclipse crossed the Atlantic and entered Turkish waters. Turkey did not apply the Western sanctions regime in the same manner as the UK and EU, and Eclipse subsequently remained around the Turkish coast for an extended period. The 140-metre Solaris, also publicly linked with Abramovich, followed a similar course.
Eclipse spent considerable time near Marmaris and was photographed departing the area in August 2025 after a stay lasting more than two years. Her movements since 2022 have therefore been much more limited than the broad international operating pattern that characterised the earlier part of her life.
As of July 2, 2026, publicly available AIS information places Eclipse in the Sea of Marmara, with Gölcük, Turkey, listed as her most recent port. The data indicates that she arrived there on March 29, 2026. Gölcük lies east of Istanbul and is associated with naval, shipbuilding and repair infrastructure.
The publicly available information does not confirm why Eclipse is there. It would therefore be speculative to state that she is undergoing a specific refit, repair or technical programme without direct evidence from the yacht, shipyard or management team. AIS positions should also be treated as recently reported information rather than an absolute guarantee of a yacht's present position, since transmissions may be delayed, incomplete or deliberately restricted.
The available evidence nevertheless indicates that Eclipse remains in Turkish waters rather than returning to her previous seasonal programme of Caribbean winters and Mediterranean summers. This change illustrates how political and legal events can affect the practical life of even the most capable and valuable private yacht.
Eclipse is no longer the longest yacht in the world, yet losing the record has done little to diminish her significance. Length records are temporary. Another owner can always commission a yacht that is longer, larger or more expensive. Successful architecture is more difficult to surpass.
Eclipse remains important because her immense scale was translated into a coherent design. The helicopter facilities, swimming pool, owner's deck, lifeboats, guest accommodation and technical spaces were not treated as unrelated displays of wealth. They were incorporated into one balanced and recognisable piece of naval architecture. The result is a yacht that still appears modern without relying on fashionable styling devices.
Her history also extends far beyond design. Eclipse represents the globalised superyacht world of the early 21st century, when extraordinary private wealth, German engineering, British design and international cruising combined to produce vessels of unprecedented scale. Her later years demonstrate the limits of that mobility, as sanctions, ownership scrutiny and geopolitics reshaped where she could operate and how she was perceived.
From a distance, Eclipse still appears calm, balanced and almost timeless. Behind that appearance lies a yacht of immense technical complexity, created by one of Germany's most experienced shipyards and one of Britain's most influential yacht designers. She was built to cross oceans, carry helicopters, accommodate dozens of people and operate as a private world at sea. More than 15 years after delivery, Eclipse remains not merely a former record holder, but one of the defining superyachts of her generation.
