Lurssen's 109m O3 Delivers After Changing Owners Mid-Build

Why did O3 take eight years to build?

O3 took roughly eight years to reach delivery because the yacht changed owners and design teams mid-construction: sold new in March 2018, resold with her steel hull already built in 2022, and finished under a completely different design brief.

Moran Yacht & Ship brokered the original 2018 sale, when the project carried the name Project Icecap and construction began at Lurssen's Peene-Werft facility in Wolgast, on Germany's Baltic coast. That hull, laid down to an ice-classed specification from the start, changed hands again during construction in 2022, at which point work moved to Lurssen's Hamburg yard for the rest of the build. A yacht this size ordered new typically reaches delivery in four to five years. O3's timeline roughly doubled that, and the extension happened entirely on the far side of a resale rather than because the build itself ran long. Moran, among the busiest brokers of large new-construction contracts, held the file through the change of hands, giving the 2022 owner continuity of representation even as the design brief changed completely underneath the same hull.

Sea trials only began in late January 2026, more than seven years after the keel went down, and delivery followed in June. O3 made a brief stop in Kristiansand, Norway on 6 June before continuing north along the Scandinavian coast, a routing that doubled as an early demonstration of the ice-classed hull she had been built around from the start.

What changed on O3 after her 2022 sale?

The new owner kept Salt Ship Design's original naval architecture and steel hull but replaced both design teams above it, bringing in Espen Oino International for the exterior and the Parisian studio CG Design for the interior, under project oversight from Occam Marine.

The visible result is a reworked profile: a large, certified helideck added over the aft section, and an extended aft deck built out beneath it, both serving the expedition brief by adding reach into locations with no port infrastructure. Salt Ship Design and the original interior team, Adam Lay Studio, had drawn the first specification for the 2018 buyer. None of that superstructure design survived the 2022 handover. Only the hull, its structure and the general arrangement carried over.

A redesign this late in a build is unusual, because it means paying twice for design work on a hull that is already fixed rather than adjusting drawings before steel is cut. On the evidence of O3's finished result, it is also a way to inherit years of structural work on an ice-classed hull that would take a comparable amount of time to build from nothing, while still ending up with an entirely owner-specific yacht above the waterline.

What can O3 actually do that a Mediterranean superyacht cannot?

O3 is built to Ice Class 1B on a 109-metre steel hull with aluminium superstructure, a genuine structural rating for operating in broken and first-year ice, and she carries up to 20 guests in 10 staterooms with room for up to 30 crew.

Three Wartsila 9L20 diesel-electric engines, rated at roughly 2,692hp each for a combined output near 8,076hp, drive the 6,561 GT hull, a tonnage figure BOAT International and YachtBuyer both publish independently. The 17.5-metre beam and 4.5-metre draught give her the volume for a beach club, pool, elevator and expanded tender garage, plus cargo capacity for equipment an owner cruising remote coastlines needs and a standard 100-metre Mediterranean charter yacht does not carry. YachtBuyer lists a top speed of 24 knots, fast for a true expedition yacht of this displacement, though no second outlet has independently published that figure.

The axe-style bow and forward-sited superstructure, both carried over from Salt Ship Design's original naval architecture, are functional choices on an ice-classed hull rather than styling ones. They are the same features that let the 2018 specification serve as the base for a completely different owner's yacht four years later, because the part of the design that actually has to survive contact with ice was never up for redesign. The interior carries the same split: one owner's suite and four VIP cabins sit forward, with five further guest cabins aft, a layout CG Design inherited as a brief rather than chose from scratch.

Who owns O3?

Neither Lurssen nor any of the trade outlets that covered O3's delivery, including BOAT International, Superyachts.com and Mercer Yachting, have identified who owns her.

That looks like a deliberate absence rather than an oversight. Yards and owners' representatives routinely withhold a name when an owner wants it withheld, and a 2022 resale arranged privately, mid-construction, is exactly the kind of transaction that leaves no public paper trail to work from. Moran Yacht & Ship, which managed the original new-build project from inception, has said only that it was proud to have played a role in bringing O3 to life, calling her one of the most technically ambitious superyachts built in recent memory, without naming a client on either side of the 2022 sale.

No price has been published for the original order, the 2022 resale, or the redesign that followed it, and YachtBuyer's own listing records her simply as not currently for sale. For a buyer weighing a similar project, that silence is itself the data point: an eight-year, twice-sold, fully redesigned build of this kind carries no public benchmark for what it should cost, only for what the finished yacht eventually looks like.

Is O3 part of a bigger expedition-yacht trend at Lurssen?

O3 is one of several ice-classed, genuinely expedition-capable Lurssen deliveries this year, and points to a yard putting real polar-rated engineering behind the explorer label rather than just an expedition-styled hull.

The distinction matters because "explorer" has become a marketing term applied loosely across the size range, while an Ice Class 1B rating is a specific, classed structural standard that a naval architect either designs to or does not. Salt Ship Design's original hull for O3 was built to that standard from 2018, before any resale, which is why a 2022 owner could inherit a genuinely capable platform rather than a merely rugged-looking one. Lurssen delivered another ice-classed explorer this year in the 114-metre Nausicaa, built diesel-electric and designed to run on fuel cells once the technology and the fuel are both available, which Yotters covered on her August delivery. Two genuinely polar-rated hulls from one yard in a single year is a small sample, but it is a different order book to the flybridge and explorer-styled cruisers most yards call by the same name.

For an owner comparing new builds now, O3's history is a useful data point on timing risk rather than a template to copy. A resale mid-construction can preserve years of structural work on a hull built to a real classification standard, but it does not shorten a build, and a buyer underestimating that trades a current explorer-class order book slot for less certainty about the schedule they will actually get.
