Jeff Bezos is one of the richest men in the world. The Amazon founder, who is worth an estimated $245 billion, shelled out $237 million on his Miami compound where he currently resides with his wife, Lauren Sánchez. And when he moved there, the sale of his Seattle home was the most expensive home ever sold in Washington State at $63 million.

But the fourth-richest man in the world spent even more on his superyacht—more than double, to be exact. He broke another record when he commissioned his superyacht, Koru, in 2018 from Dutch yacht builder Oceanco. (Oceanco is owned by another billionaire, Valve’s billionaire cofounder Gabe Newell, who received his own $500 million superyacht just last week.)

Bezos reportedly paid $500 million for his 417-foot-long vessel—and it’s currently the world’s largest sailing yacht, according to Boat International. The yacht is so big, The New York Times reported it was actually too large to be docked with other private yachts in Florida. Oceano has also commissioned yachts for other celebrities and business people including filmmaker Steven Spielberg, Dallas Cowboys owner Jerry Jones, and Home Depot cofounder Arthur Blank.

Koru was first seen at sea in 2023, according to the SuperYacht Times when it took a trial run in the North Sea from the Netherlands. About two months later, Bezos and Sánchez were spotted sailing on it around Mallorca, Spain. Bezos even paid an extra $75 million for another yacht to support his superyacht: a vessel called Abeona that also has a helipad.
