Oceanco unveils the 364-foot Y726, one of its largest megayachts

Dutch yacht builder Oceanco has unveiled its latest masterpiece, Y726, a 364-foot superyacht that ranks among the largest vessels the shipyard has ever built. With a gross tonnage of 4,550 GT, the Y726 blends engineering prowess with opulent design, setting a new benchmark in luxury marine craftsmanship.

Commissioned in 2022 by a seasoned yachting enthusiast, the Y726 was developed in close partnership with some of the industry’s most celebrated names. The yacht’s sleek exterior was designed by Espen Øino International, while the interior was brought to life by UK-based Mark Berryman Design. Naval architecture was a collaboration between Lateral Naval Architects, Oceanco’s in-house team, and Dan Jackson of Falcon Yacht Management, representing the owner.

“This project is the result of bold design ambition and robust engineering,” said Lee Archer, Programme Director at Lateral. “Y726 represents not only high-level design execution but also the strength of collaboration in bringing exceptional ideas to life.”

Despite not surpassing the size of Infinity, Oceanco’s current flagship at 384 feet and 4,978 GT, Y726 still stands tall as a commanding presence at sea. The yacht has a beam of 52 feet and will begin sea trials in the coming months before its official delivery later this year. Oceanco’s fleet also includes the record-setting 417-foot sailing yacht Koru, reportedly owned by Amazon founder Jeff Bezos.

Beyond its impressive size, Y726 is designed for ultimate luxury. The yacht features a cinema lounge, a fully equipped gym, a spa with sauna and steam room, and a beach club with a bar opening onto the swim platform. Outdoor amenities include a winter garden, a private Jacuzzi suite, an alfresco cinema, and a pool-equipped entertainment zone. It accommodates up to 28 guests and 34 crew members.

“This yacht has been built on trust, vision, and deep collaboration,” said Edske Smit, Project Director at Oceanco. “Y726 is not just a vessel—it’s a floating experience of innovation, elegance, and engineering at its peak.”
