Google co-founder Sergey Brin’s superyacht Dragonfly is so enormous that even stopping for fuel becomes a commercial-scale operation. Measuring 466 feet (142.1 meters), the Lürssen-built yacht is far too large for the kind of fuel pump found at an ordinary marina, forcing it to use Gibraltar’s industrial bunkering infrastructure instead. Delivered in 2024 and with an estimated value of around $450 million, the luxury vessel’s massive size forced her to be docked at a Spanish Navy cruise berth recently.
In a YouTube video from the channel Gibraltar Yachting, Dragonfly can be seen berthed alongside Gibraltar’s commercial-scale bunkering terminal, with enormous shoreside fuel tanks towering behind it. The striking scene offers a glimpse of what refueling a yacht of this size actually looks like. It appears less like a luxury marina stop and more like a visit from a small ship to a working fuel port.
A fuel stop measured in hours
The scale of Dragonfly becomes even clearer when the fuel figures are considered. The Gibraltar bunkering operation can deliver fuel directly through its pipe system at rates of up to 80 metric tons per hour. Even at that impressive rate, Dragonfly would take about 13 hours to tank up, depending on the amount required.
Gibraltar’s fuel infrastructure includes 18 tanks with around 3,200 metric tons of marine gas oil and automotive gas oil storage, along with a separate facility capable of storing another 13,350 metric tons of marine gas oil. The operation also has barges for vessels refueling at anchor or requiring different fuel grades.
For Dragonfly, even a partial 500-metric-ton refill would be enormous. That amount translates to roughly 581,000 liters of diesel and could cost approximately $690,000 to $720,000 at indicative Gibraltar MGO prices of $1,380 to $1,440 per metric ton. At the maximum pumping rate, it would take about 6¼ hours. A 1,000-metric-ton uplift would mean around 1.16 million liters, a bill of roughly $1.38 million to $1.44 million and about 12½ hours of pumping.
Using 20,000-liter fuel trucks would be even more impractical. A 1.16-million-liter delivery would require roughly 58 truckloads, or around 60 tankers when rounded, and could take about two days.
A floating luxury complex that still needs fuel
Dragonfly is not simply a giant hull with lavish cabins. The 9,408-gross-ton yacht has a diesel-electric hybrid propulsion system powered by two MAN 16V28/33D diesel engines, each roughly the size of a semi-truck, weighing 44 tons and generating 9,760 hp. Together, they propel the enormous vessel to a reported top speed of 24 knots. It was designed by Germán Frers, with Nauta Design responsible for its interiors and social spaces. The yacht also has a dedicated business deck, reflecting Brin’s apparent desire to work while traveling.
Inside and across its five decks are the kinds of facilities expected on a billionaire’s yacht, including a glass-bottom swimming pool, spa, gym, games room, cinema, beauty salon, elevators, galleys, refrigeration and laundry facilities. There are also navigation and communications systems, water-making and waste-treatment equipment, plus infrastructure supporting tenders and helicopter operations.
The hybrid setup can make propulsion more efficient and quieter, but it does not make Dragonfly independent of fuel. Its diesel engines remain essential to generating the energy needed to move the yacht and support its enormous onboard hotel load.
Gibraltar is particularly convenient for a vessel of this size because it sits at the gateway between the Atlantic and Mediterranean. More than 60,000 vessels pass through the Strait each year, while Gibraltar is a major bunkering hub with competitive fuel pricing and infrastructure designed for vessels much larger than those found in conventional yacht marinas.
Dragonfly’s Gibraltar visit also appears to have been an operational stop. AIS records show the yacht traveled roughly 463 nautical miles from Palma de Mallorca toward Gibraltar before continuing on its journey. Its latest reported destination is Alcudia, Spain, according to MarineTraffic, with the yacht heading back toward the Balearics.
The visual of Dragonfly next to Gibraltar’s fuel tanks is truly impressive, giving a sense of scale of the gigantic luxury vessel. It neatly captures the logistical reality of owning a 466-foot private yacht. When it needs fuel, even the fuel station has to be built on a monumental scale.
