Seven Seas yacht: 109 m Oceanco (2023), Sinot design

In short

Seven Seas is a 109-metre motor yacht that Oceanco delivered in July 2023 after building her as project Y720; she was the Dutch yard's fourth-largest delivery at the time (Boat International). Her exterior and interior are by Sinot Yacht Architecture & Design, the yard's first exterior collaboration with the studio, with American designer Molly Isaksen on the interior and Lateral Naval Architects on the naval architecture (Boat International, Oceanco). She was the first yacht built to the LY3 code to carry a marine evacuation system (Boat International), and Boat International reported in September 2026 that she was commissioned by the American filmmaker Steven Spielberg (Boat International). She is a different yacht from the 86-metre Oceanco Seven Seas delivered in 2010, which she is believed to have succeeded (Boat International).
