The 20 biggest superyachts under construction in the world

Every year, the world’s most premium superyacht builders push the boundaries of design and construction to build the biggest superyachts in the world. German yard Lürssen has the most large-scale superyacht projects underway, claiming seven from this list, while Dutch yard Oceanco has three. The largest of the lot, the 182.9m REV Ocean, is set to become the most advanced and largest research vessel in the world when it is delivered. In second place, the 158m Project Blue is the largest Lürssen on the list and due for delivery in 2023. Several projects in this list are on hold, casting doubt over their scheduled delivery dates. The 141m Dream Symphony, currently underway at Dream Ship Victory in Turkey, is one such stalled project alongside the 126m Privilege One and 120m Project Y910

Set to become the most advanced research vessel in the world, REV Ocean will be 2.3 metres longer than Azzam, the world’s largest superyacht. Although REV Ocean will not be considered a fully-fledged superyacht, it has been developed with legendary superyacht designer Espen Øino. REV Ocean will be packed with advanced oceanography equipment and has been designed to be as fuel-efficient as possible. Other onboard features include storage for an autonomous submersible, as well as laboratories and an auditorium. Accommodation is for 36 guests and 54 crew members. REV Ocean was technically launched in August 2019 at the Fincantieri/ Vard Holdings yard in Tulcea, Romania.
