The 21 biggest superyachts under construction

29 November 2022• 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...

Opera | 146m

Lürssen has the most large-scale projects underway with eight 100m+ vessels in build. The largest of which, Opera, is believed to be the reincarnation of Project Sassi that caught fire in 2018 at Lürssen’s Bremen yard. There are reports that the steel hull was largely rescued but the aluminium elements of the superstructure had to be scrapped. Either way, the yacht looks every inch a classically muscular Lürssen and was recently spotted on sea trials as she nears completion.

Project Luminance is another powerful-looking Lürssen with a classic raked bow and a high, brooding superstructure. She looks like she runs to seven or even eight decks, if you include a small recess in front of the mast that appears to have been designed as an observation point. Otherwise, very little detail has escaped about this yacht.

Another enormous Lürssen project, rumoured to be codenamed Project Alibaba, left the construction shed in May 2022 in two halves. 

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.

Widely reported to be the new boat for Amazon founder Jeff Bezos, Oceanco’s Project Y721 remains shrouded in secrecy. However, the tight-lipped Dutch yard couldn’t prevent the world getting a look at the huge hull of the yacht as it was floated downstream from Alblasserdam for final commissioning in Rotterdam. At 127 metres long, it is set to be the world’s largest true sailing yacht, eclipsed only by the sail-assisted Sailing Yacht A. Three slender masts make this a schooner, with what appears to be an in-boom furling Bermuda rig.

Project JAG | 122m

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).

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 which launched in 2018. 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.

Freire NB-724 | 111.9m

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. This is borne out by the involvement of the Norwegian Marin Teknikk as naval architect and exterior designer. Interior designer Dickie Bannenberg reports that the boat will have a gross tonnage in excess of 7,000GT and, “a robust functional exterior wrapped around a 100 per cent B&R-designed interior”.

Oceanco Y722 | 110m

Oceanco Y722 is the first of two mysterious projects by the Dutch shipyard to make this lineup. This 110 metre superyacht was glimpsed in May 2022 when the aft portion of the vessel was relocated into a new shed. Once launched, the project will take its place as the third-largest delivery to be made by Oceanco.

Project Cosmos | 110m

Project Cosmos is yet another mega build by German shipyard Lürssen. Its design team has yet to be revealed – and its project name gives very little away.

Delivery of the unnamed 109 metre is imminent as she sits at the shipyard undergoing final touches. Still known as Y720, the yacht has a classical profile with a heavily raked bow. However, Sinot Yacht Architecture & Design has given her an ultra-modern aesthetic through the use of planar surfaces, lots of vertical glazing and inverted overhangs between decks. The boat has been given glossy grey painted topsides, which contrast with the black windows and white, ruler-straight decks of the superstructure.

Project Icecap | 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.

Oceanco Y1050 |105m

Almost nothing is known about this yacht from Oceanco besides its codename. Even by the standards of the superyacht industry, secrecy has been absolute, with not even a photograph slipping through the net. She is due for delivery in 2023 so watch this space.

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.

Project Titanium | 100m

Announced in March 2021, the 100 metre hybrid superyacht Project Titanium is set to be built under The Italian Sea Group's Admiral brand. Designed inside and out by Winch Design, Project Titanium is scheduled for delivery in 2025 and will balance “high-quality standards with high-tech solutions” while emphasising “attention to eco-sustainability”.
