The 19 biggest superyachts under construction

21 April 2023 • Written by Holly Overton

Take a peek inside the sheds as we shine a light on the largest superyachts currently under construction, starting with a quartet of Lürssens...

Project Luminance is a powerful-looking Lürssen with a classic raked bow and a high, brooding superstructure. Her two-tone exterior in navy blue and silver features two helipads and a large infinity pool and is the work of Espen Øino, marking the 30th collaboration between the designer and the shipyard. Interior design is the work of Francois Zuretti but details remain a closely guarded secret. Delivery is slated for 2023.

Another enormous Lürssen project, rumoured to be codenamed Project Alibaba, left the construction shed in May 2022 in two halves. Very little else is known about this elusive project.

Unknown Lürssen | 130m

This unnamed project is currently under construction at Lürssen and will be the fourth biggest project delivered by the shipyard to date when it hits the water in 2025.

Commissioned by a repeat client as a replacement for his 96-metre superyacht, Project JAG is the owner's third Lürssen. Nuvolari Lenard has given this big vessel a futuristic, winged mast structure and a long pointed bow with what looks like a kind of bowsprit walkway. She can accommodate 20 guests in 11 cabins, with berths for 40 crew (that's two crew to each guest). We expect to see a glimpse of her in her final form sometime soon.

Project Signature | 120m

Announced in September 2020, the 120-metre in-build Amels superyacht Project Signature is designed by superyacht designer Espen Øino and marks the second custom collaboration between the studio and the Dutch shipyard. Described as a “unique and powerful” vessel, Project Signature is set to be a "green, ecological superyacht" with diesel-electric engines and Azipod propulsion with superlative noise and vibration management. Project Signature is due for delivery in 2025.

Abeking 6514 | 120m

In October 2021, German shipyard Abeking & Rasmussen announced it had signed a contract to build a 120m+ superyacht. The Abeking 6514 will be the largest project undertaken by the shipyard since the commissioning of 118-metre Project 6507 (also found on this list) which remains under construction.

Feadship's future flagship was spotted for the first time as she was floated out of her construction shed in April 2022. The project, known as Feadship 821, is said to be the largest yacht built by the Dutch shipyard to date, usurping the 110-metre Anna and supposedly topping the recently launched Project 1010. Project 821 is due for completion in 2024.

The 4,999GT yacht marks a significant milestone for Feadship as its longest launch to date, surpassing the 110-metre Anna when she hit the water last year. The design comes from the pen of the redoubtable Espen Øino, whose fluid lines are interrupted by an unusual pair of “eyebrows” amidships. Otherwise, Project 1010 displays a dark blue hull, a heavily raked white superstructure and a unique observation lounge “bubble” deck with curved floor-to-ceiling glass, tucked just under the mast.

Setting a new size record for an Abeking & Rasmussen build, this project has been kept under tight wraps. The 118-metre Project 6507 is said to be designed for adventurous cruising, with lots of room for tenders, toys and even a submarine. One report claims there is also a Neptune Lounge, where guests can relax and dine. The yacht’s designer, Joseph Dirand, is better known as an architect and a furniture designer, who makes much of his “French touch” and art of living. His biggest project to date has been a 26-metre Otam.

Project Cosmos | 114m

Project Cosmos is yet another mega-build by German shipyard Lürssen and was glimpsed for the first time in March 2023.  The vessel was commissioned by a Japanese owner in 2020 and features an explorer-style profile with a glass observation lounge, swimming pool and an unusually large tender bay. Her exterior is the work of Australian designer Marc Newson, whose portfolio includes the 139.7-metre Solaris.

Built by Freire, a Galician yard with a background in sturdy ocean-going fishing and research vessels, NB-724 is believed to be a serious expedition yacht. Marin Teknikk, whose portfolio includes two Kleven explorers Andromeda and Ulysses, is responsible for the naval architecture while the interior and exterior design is the work of Bannenberg & Rowell. Dickie Bannenberg reports that the boat will have a gross tonnage of 6,950GT and, “a robust functional exterior wrapped around a 100 per cent B&R-designed interior”. The vessel is the largest private yacht built in Spain.

Oceanco Y722 and Oceanco Y723 | 111m

Oceanco Y722 and Oceanco Y723 are two mysterious projects by the Dutch shipyard. The first of the two 111-metre superyachts was glimpsed in May 2022 when the aft portion of the vessel was relocated into a new shed. Once delivered, the projects will take their place as the joint third-largest deliveries to be made by Oceanco following Koru and Infinity.

Shackleton | 107m

When she was revealed last summer at Lürssen’s Wolgast yard, it was clear that Project Icecap was shaping up to be a very capable explorer yacht. With an axe-style bow and the superstructure well forward, the yacht should punch safely through big seas, while offering big cargo-carrying capacity on the open aft deck. Owner’s rep Moran Yacht & Ship described the boat as diesel-electric powered. An ice-classed hull, heli-hangar and forward observation lounge are also on the spec sheet. 

Freire Explorer | 105m

Little is known about the 105-metre explorer under construction at the Freire Shipyard. The contract was signed in July 2021 but no further details have been released. She is expected to be delivered in 2024.

H | 105m

The 105-metre project Y1050, also known as H, is finishing up outfitting at Oceanco following a full-scale rebuild at her home shipyard.  In a statement, Oceanco called the rebuild of 1050H a first of its kind. "The yachting world has seen commercial vessels converted into superyachts, and heritage yachts being returned to their original glory, but this is the first time a superyacht has been recreated to face the future as a wholly new, contemporary vessel," said a spokesperson for the yard. Few details have been revealed to the media.

Project JASSJ | 103m

Lürssen revealed the first details of the 103-metre Project JASSJ at the Monaco Yacht Show in 2021. Designed inside and out by RWD, Project JASSJ features accommodation for a total of 22 guests in 11 cabins, with an “industry-leading” beach club aft. Moran Yacht & Ship negotiated the build contract and will supervise the build.

Feadship 1011 | 103m

The third Feadship to make this line-up of the biggest yachts under construction is a 103-metre project with delivery in 2024. The yacht, which was last spotted en route to the Feadship shipyard in Makkum, is supposedly designed by Sinot Exclusive Yacht Design with clean lines and a vertical bow.

Dorries 100M+ | 100m

In August 2022, it was reported that Dörries Yachts had signed a contract for the construction of a 100-metre-plus superyacht for an American tech mogul.
