On 4 August Oceanco confirmed that Leviathan will be at Port Hercule in September. One line in a press release, and the top of the Monaco Yacht Show fleet list rearranged itself seven weeks before the doors open. Until then the largest yacht booked for the show was Nixie, Lürssen's 102.4-metre June delivery. Now the biggest hull in Port Hercule is Dutch, and the margin is 8.6 metres.
We have already introduced Leviathan to our readers: Gabe Newell's 111-metre Oceanco, flagship of the Inkfish research fleet, delivered in November 2025. What Monaco adds is the company she keeps at the quay, and what her arrival does to the show's own scoreboard.
Oceanco brings two, and one of them is second-hand
The yard has taken a berth at the cruise terminal for Leviathan and Draak together — a new build and a rebuild, moored side by side. Oceanco has not shown that pairing at Monaco before.
Draak is the ex-Tranquility, and before that the ex-Equanimity: a 92.8-metre Oceanco from 2014, handed back to her owner on 30 June after a rebuild by the yard's Life Cycle Support division. We covered that job in February. The compressed version: helideck removed, tender deck and a 12.6-tonne crane installed in its place, beach club rebuilt as a dive centre with a decompression chamber, main-deck saloon converted into a mess that guests and crew share. A charter flagship deliberately demoted into a science platform.
Berthing the two together is a positioning move. Rebuild work at the big Dutch yards has always been the quiet half of the business — no launch party, no render. Oceanco is giving it the same frontage as the newbuild hall.
Marcel Onkenhout, CEO, Oceanco:“Every owner we work with brings a different vision, and every project challenges us in a different way. With collaboration guiding every decision, we are looking forward to showcasing two yachts at this year's Monaco Yacht Show that truly reflect this ambition.

A rebound, not a record
The "largest yacht at Monaco" line moves around more than you would think. In 2023 it was the 115-metre Ahpo. In 2024 it was Golden Odyssey at 123.2 metres, the largest yacht ever to attend the show. Then 2025 dropped to 107 metres, after Feadship's 119-metre Breakthrough sold and pulled out of the fleet list.
So 111 metres claws back about a quarter of the ground lost last year and still finishes some twelve metres short of the 2024 mark. On the list as it stands — the organiser is still adding yachts weekly — that makes two consecutive Septembers below Monaco's own high-water mark.
Length is the headline; volume is the change
Leviathan measures 4,970 GT on a 111-metre hull with a 17.8-metre beam. Nixie, the yacht she displaces at the top of the list, measures 3,420 GT at 102.4 metres.
That is 1,550 GT of difference across 8.6 metres of hull — a gap length alone cannot explain. Gross tonnage counts enclosed volume, and the two yachts spend theirs on opposite briefs. Nixie is charter specification, exterior and interior both by RWD, 20 guests in 10 staterooms with 34 crew, and she went straight onto the charter market. Leviathan carries a dive centre, a laboratory, a hospital, a 3D-printing workshop, a tri-fold beach club, a gaming lounge and a basketball court, and answers to nobody's charter calendar.
Volume is where the last decade of large-yacht design has quietly gone, and Leviathan is the clearest example Monaco will have on the water this year.
The rest of the list
This is the 35th edition, running 23–26 September at Port Hercule. The organiser expects around 120 yachts by opening day and counts 43 world premieres, every one of them delivered during 2026.
Toby Moore, CEO, Informa Prestige:“A new commission at a leading shipyard means waiting until 2028 or beyond.
”
That is the argument for a show built around finished boats rather than renders. Behind Leviathan, Nixie and Draak, the confirmed fleet drops to the 88-metre Angelique, the largest Turquoise Yachts has ever built. Then Pangea, the first completed Amels 80; Golden Yachts' 78-metre Malia; N2H, Turquoise's 76-metre first hybrid; the 73-metre Virtuosity with her underwater lounge; and Feadship's 72-metre Vanish. Italian yards, which account for 52 per cent of global superyacht production, dominate the series-production premieres.
The headline number is back above 110 metres. Whether it stays there is a question for the 2027 delivery list.
