Steve Kozloff’s G-Quest Gigayacht Can Circumnavigate the Globe on One Tank


It makes logical sense that the bigger a vehicle is, the more fuel it will take to operate it. That would seem to hold true for watercraft especially. Not only do they have their massive size working against them, they’re also constantly pushing against water and currents, which would require a substantial power output. Somehow, though, California-based designer Steve Kozloff has beat that equation, coming up with a 705-foot Gigayacht concept that can reportedly circle the globe on just one tank of gas.

The G-Quest Gigayacht is designed to be an oceanographic vessel that can also deliver humanitarian aid – though, you may not guess that given how luxurious the massive yacht is. The yacht features a displacement hull and has a medical laboratory complete with MRI and X-ray facilities. And if that wasn’t enough, there’s also an ophthalmology department and a suite for your dentist.

The yacht also offers 20 hospital beds and an operating room. Researchers will make use of the fleet of exploration vehicles berthed in the yacht, which includes two Cessna seaplanes, six Candela electric foiling tenders, an electric landing craft, a U-Worx submarine, and three Taiga electric orca Jet Skis. A 6,500 square foot aircraft hanger houses two Sikorsky S-92 helicopters and there is a garage for two SUVs. Plus there’s a dive centre with a decompression chamber.

The upper three decks are for the owner and guests (G-Quest Gigayacht can host a total of 26 guests and 150 crew members), while the lower decks are for the labs and hospital. A large solarium with a saloon and dining room take up the bow of the owner’s suite, where you’ll also find a private pool. The flybridge offers a pool with spa, lounge, and half basketball court.

But how does the G-Quest Gigayacht make it around the globe on one tank of gas? For starters, it will use alternative fuels like hydrogen or biodiesel, which will power battery technology. Plus an onboard steam turbine will help to generate power for the azimuth thrusters. According to Kozloff, this design would have a range of 20,000 nautical miles. And to bring all of this into reality, you’ll only need somewhere around $1 to $1.2 billion.
