The 20 biggest superyachts under construction

6 December 2024 • Written by Milly Robinson

This year, the industry has celebrated several high-profile launches and deliveries, including the world's first fuel-cell superyacht and Dragonfly, the highly anticipated, 142.1-metre Lürssen. But in the world of superyacht construction, there's always something to look forward to. To mark the release of the 2025 Global Order Book, BOAT steps inside the sheds and spotlights the largest superyachts currently under construction...

REV Ocean | 194.9m

At 194.9 metres, REV Ocean retains its status as the largest yacht under construction globally. She is set to be the flagship of Norweigan shipyard Vard, with a design courtesy of Espen Øino and H2 Yacht Design. Work on this monumental project paused in 2021 and resumed in 2023, with launch now anticipated for 2025. At the 2024 Explorer Yachts Summit, REV Ocean CEO, Nina Jensen, provided insights into the yacht’s ambitious mission, design and construction journey, noting its potential as a scientific research platform. Jensen, who has previously described REV Ocean as a "science vessel on steroids", highlighted the scale and scope of the record-breaking initiative.

Project Deep Blue | 134.2m

Project Deep Blue is a 134.2-metre motor yacht currently under construction by Lürssen, with delivery expected in 2025. The last reported sighting of Project Deep Blue was in 2023 when she was at the yard's facility in Bremen, Germany preparing to have her bow segment attached. While no further updates have been confirmed, Project Deep Blue is one of the most closely watched builds at the yard.

Project Vela | 130m

Project Vela is a 130-metre sailing yacht currently being built in Croatia. Initial construction began in May 2023, although details of the project remain confidential. After many years of development by the owner and his team, the yacht is due for delivery in the summer of 2026.

Lurssen 13798 | 120-130m

Few details are available on the Lürssen 13798, commissioned in 2023. The yacht is projected to measure between 120 and 130 metres in length and boast an estimated gross tonnage of 10,500GT. Delivery is expected in 2027.

Project Tanzanite | 120m

Set to become the flagship of Amels, Project Tanzanite is a 120-metre motor yacht under construction in the Netherlands, with delivery slated for 2025. Designed by Espen Øino, she is currently the largest yacht in build in the Netherlands and was last seen arriving at Damen Yachting’s Vlissingen facility in June 2023 for outfitting. Interior renderings revealed in May 2024 by Zuretti Design showcase a warm, contemporary aesthetic with a cream and brown palette. The interior proposal also shows the yacht to be fitted with curved furniture, completed by wood and marble accents.

Project 821 | 119m 

The 118.8-metre Project 821 is a record-breaker. The first superyacht to utilise fuel-cell technology (and the largest motor yacht launched in the Netherlands), she marks a "new, clean technology for the world" according to Feadship director and CEO Jan-Bart Verkuyl. Other highlights include a semi-submerged Neptune lounge, cinema, library, hospital facility and 8.2-metre pool with contraflow. Project 821 most recently completed her sea trials near IJmuiden, Amsterdam, with delivery imminent. She is available for sale with Edmiston.

Lürssen 13797 | 116m 

This big Lürssen build was commissioned in 2022 by an American owner. Specific details about the Lürssen 13797 remain tightly under wraps, though she is believed to have an impressive gross tonnage of 5,350GT. Delivery is scheduled for early 2026 according to BOATPro.

Project Cosmos | 114.2m

Project Cosmos is yet another mega-build by German shipyard Lürssen and was last seen in August 2023 in transit from the yard’s facility in Rendsburg. The 114.2-metre project has her delivery set for 2026, with interior and exterior lines courtesy of Marc Newson. The fuel cell-powered vessel was commissioned by a Japanese owner in 2020 and features an explorer-style profile with a glass observation lounge, swimming pool and a large tender bay.

Arwen | 113.5m

In July, German shipyard Dorries Yachts unveiled the "Nest", the standout observation platform on its 113.5-metre Project Arwen. Under construction in Bremerhaven and set to launch in 2026, she will serve as the flagship of Dorries Yachts. Her design stems from the drawing boards of Pindaros and Andy Waugh Yacht Design, with naval architecture by Azure Yacht Design and Naval Architecture. Renderings revealed in July 2024 showcase an extensive list of amenities, including a 20-metre long swimming pool (which can be hydraulically raised to extend the deck area), a multi-level spiral staircase, a helipad and a gym.

Oceanco Y726 | 111m

With a delivery date set for summer 2026, Oceanco's Y726 entered outfitting in December 2023 and was last seen at the Alblasserdam facility, wrapped in an unconventional graffiti-style design by a Rotterdam-based artist. Interior details by Mark Berryman are described as "refined", with little else disclosed. Leisure features revealed in 2023 include a cinema lounge, gym, spa and a multi-purpose entertainment area with a Jacuzzi and swimming pool. The beach club features a bar that opens directly onto the swimming platform.

Oceanco Y722 | 111m

Joining Project Y726 is Oceanco's Project Y722. Last seen in June 2023 as she left the construction shed for outfitting at Alblasserdam, her delivery is slated for summer 2025. Expected to sit just under 5,000GT, she will be the largest yacht by volume built by the Dutch shipyard. As of 2023, her design proposal from the yard was set to include a diesel-electric power plant and a battery-powered system for extended emission-free operation. She promises to be suited for "scientific research and discovery". 

Project Icecap | 107m

First sighted at Lürssen’s Peene-Werft naval yard in 2022, Project Icecap is set to be a highly capable explorer yacht. The 107-metre vessel, with its axe-style bow and forward superstructure, will safely handle rough seas and offers ample cargo-carrying capacity on the open aft deck. Delivery to her owner is set for early 2025. Key features of Project Icecap include an ice-classed hull, a beach club, an elevator, a swimming pool and a helipad.

Project Incógnita | 107m

This June saw the launch of Freire’s 107-metre Project Incógnita from its shipyard in Vigo, Spain. Previously known as NB-729, details have remained scarce since Freire first secured the contract in July 2021. She is on track for delivery in 2026, with images showing the completed hull and pending installation of the superstructure. Project Incógnita will span six decks, constructed from steel and aluminium, with her exterior and interior designers yet to be revealed.

Project JASSJ | 102.7m

Lürssen first unveiled the details of the 103-metre Project Jassj at the 2021 Monaco Yacht Show. Designed by British studio RWD, the superyacht offers accommodation for 22 guests across 11 cabins and features an "industry-leading" beach club aft. In December 2023, she was last seen emerging from the shed at the Rendsburg facility during her technical launch. Project Jassj, while cloaked in secrecy, remains on track for delivery in 2025.

Scheduled for delivery in July 2026, the 101.2-metre Project 1014 joins a series of confidential builds by her Dutch shipyard. She was last sighted this year as she entered the outfitting phase at Feadship's Makkum facility in the Netherlands. Project 1014 will now remain "under wraps" until her launch. Imagery reveals generous overhangs, a wide bow with railings, cutouts in the hull and curved exterior lines reminiscent of previous Feadship builds such as Faith, Viva and Tango. The main deck aft also appears to accommodate a pool.

Feadship 1013 | 101m

With a length of 101 metres, Feadship's Project 1013 is scheduled for delivery in summer 2025. She was last seen in October 2023 when her bare hull was launched at Feadship's Zwijnenburg facility. While details remain limited, initial images showcase a straight bow, glazed upper decks and a spacious aft deck potentially designed to house a pool. The lower deck features shell doors, with additional images revealing a side-loading tender garage amidships and a second garage located in the bow.

Project Jash | 120+m

Turkish shipyard AKYACHT has signed a contract for the construction of a superyacht exceeding 100 metres, known as Project Jash, with delivery scheduled for 2028. This project, set to be the largest superyacht built in Turkey, follows the shipyard's current flagship – the award-winning 85-metre Victorious. Details about Project Jash remain largely a mystery, with much of the design and specifications still undisclosed.

Project 824 | 98.5m

The last significant milestone in Feadship’s Project 824 was the joining of the hull and superstructure in September 2023. The yacht has since moved out of the NMC facility and is now in Kaag for outfitting works. Project 824 has a plumb bow, low profile and contemporary curves which draw similarities to previous Feadships Pi and Najiba. So far, little has been revealed about this project, but she remains scheduled for delivery in June 2025.

Project Titanium | 100m

With a length of 100 metres, Project Titanium is set to become the flagship of Admiral – The Italian Sea Group upon delivery in 2026. Designed by Winch Design, details taken from 2021 showed plans for a certified helicopter landing pad, expansive pool, spa and a multi-deck saloon. Since then, no further specifics have been disclosed, but her initial design was set to show "attention to eco-sustainability". 

Feadship 828 | 89m

The 89-metre Project 828 is scheduled for delivery in June 2026, after beginning construction in March 2023. With a gross tonnage of 2,623GT, she joins other Feadship projects that maintain an air of mystery, fuelling anticipation for what’s to come from the Dutch-based shipyard.

Project Spyder | 88m

The most recent progress on Project Spyder was announced in February with the laying of her keel. Scheduled for delivery in 2027, she will be the second-largest build under the Admiral brand. Designed by Espen Øino, standout features include a 10.3-metre swimming pool with a glass floor illuminating the beach club below and a foredeck sports court. FM Architettura will create her interiors.

Project Vento | 87m

Turquoise Yachts' largest project to date, the 87-metre Project Vento was transferred to the yard's site in Pendik, Turkey in late August 2023, where she has been undergoing outfitting. The yacht springs from the drawing boards of H2 Yacht Design and features a striking "Tour de France" blue hull, a 6.5-metre glass-sided pool, a drive-in tender dock and a touch-and-go helipad that doubles as a basketball court. Accommodation includes guest suites on the main deck and a private owner's suite above. She remains set for delivery in 2026.
