At 127 metres, Koru, reportedly built for Jeff Bezos, is the largest sailing yacht in the world. Over twice the length of an Airbus A330, the Amazon founder’s project took five years for Oceanco to complete and is the tallest yacht ever built, thanks to its 70-metre-high masts. While Oceanco has remained tight-lipped about the project, even down to the name of the designer, the amenities reportedly include an on-deck swimming pool, a cinema, multiple lounges, and an assortment of meeting spaces. Koru was seen in April undergoing final sea trials in the Balearic Sea, suggesting the yacht will deliver in time for the summer season. Koru’s 75-metre shadow vessel, Abeona—the largest Damen support vessel to date—is presumed to carry a crew of 37 and up to four guests in two staterooms, a helicopter, diving gear, and a large collection of water toys.
