In short

Koru is a three-masted schooner that Oceanco delivered in April 2023; Boat International's directory gives her length as 125.82 metres, although she was widely reported as a 127-metre yacht at delivery (Boat International, YachtBuyer, YachtCharterFleet). Boat International's 2021 ranking puts her first among sailing yachts and calls her the largest superyacht ever built in the Netherlands (Boat International). That ranking leaves out the 142.81-metre Sailing Yacht A, which Boat International classes as a sail-assisted motor yacht (Boat International); YachtCharterFleet calls Koru the second-largest sailing yacht in the world (YachtCharterFleet). Dykstra Naval Architects designed her exterior and Mlinaric, Henry & Zervudachi her interior, with accommodation for 18 guests in nine cabins and a crew of 40 (Boat International, YachtBuyer). She is not listed for charter and was accompanied on delivery by a 75-metre support vessel, Abeona, built by Damen (YachtCharterFleet, YachtCharterFleet). She is reported to be owned by Jeff Bezos, who commissioned her and paid a reported $500 million (Fortune, November 2025).

Questions

How big is the Koru yacht?
Koru is 125.82 metres (412 ft 10 in) long, with a beam of 17.2 metres, a draught of 5.02 metres and a gross tonnage of 3,493 (Boat International, YachtBuyer). At delivery in 2023 she was widely reported as a 127-metre yacht (YachtCharterFleet).
Is Koru the largest sailing yacht in the world?
It depends on the list. Boat International's 2021 ranking puts Koru first, ahead of the 106.7-metre Black Pearl (Boat International). That ranking does not count the 142.81-metre Sailing Yacht A, which Boat International classes as a sail-assisted motor yacht (Boat International). YachtCharterFleet calls Koru the second-largest sailing yacht in the world and notes that some consider her the largest, since Sailing Yacht A's status as a sailing yacht is disputed (YachtCharterFleet, YachtCharterFleet).
Who built and designed Koru?
Oceanco built her in the Netherlands under the build name Y721 (YachtBuyer, YachtBuyer news). Dykstra Naval Architects designed the exterior and, with Lateral Naval Architects, the naval architecture; Mlinaric, Henry & Zervudachi designed the interior (Boat International). Boat International calls her the largest superyacht ever built in the Netherlands (Boat International).
When was Koru launched and delivered?
Construction started in mid-2019 and she was launched in August 2022 (YachtBuyer). She was seen on sea trials in February 2023 and left the yard on 6 April 2023, and by the time of the delivery report had passed Gibraltar (YachtCharterFleet, YachtCharterFleet).
How many guests and crew does Koru carry?
Up to 18 guests in nine cabins, with a crew of 40 (Boat International, YachtBuyer). A 75-metre support vessel built by Damen, Abeona, accompanied her on delivery (YachtCharterFleet).
What is on board Koru?
Photos from her sea trials show an aft dip pool, a Jacuzzi on the flybridge and a crow's nest on the central mast; little has been published about her interiors (YachtCharterFleet, February 2023). The helipad and hangar are on her 75-metre support vessel, Abeona (YachtCharterFleet).
Who owns Koru?
Koru is reported to be owned by Jeff Bezos, who commissioned her from Oceanco in 2018 (Fortune, November 2025). She is not listed for charter (YachtCharterFleet).
How much did Koru cost?
Bezos reportedly paid $500 million for her, and a further $75 million for the support vessel Abeona, according to Fortune (Fortune, November 2025).
Can you charter Koru?
No. YachtCharterFleet lists Koru as not available for charter (YachtCharterFleet).
Where is Koru now?
Her live position is shown on public AIS trackers: MarineTraffic and VesselFinder. Search by IMO 9857298 or MMSI 319225400 (MaritimeOptima).
