The 110-metre Lürssen superyacht, formerly known as Project Shackleton and Icecap, has been spotted leaving Germany on her way to sea trials in Denmark. Recent images confirm her official name as O3, revealing the mammoth yacht in all her imposing detail.

Construction on the project began in 2018 and has remained highly secretive throughout the build. Delivery is expected in Q1 2026, following almost eight years of meticulous construction.
A Yacht of Many Changes
Originally sold by Moran Yacht & Ship in March 2018, the yacht reportedly changed hands again during construction in 2022. This second sale prompted several exterior modifications, including a large helideck and a heightened aft section. Her final length has not been officially confirmed by Lürssen but is expected to measure around 110 metres.
The yacht was last seen leaving the dock in 2022 from Lürssen’s Peene-Werft facilities in northeastern Germany. Her grey axe-style bow and forward-positioned white superstructure reflect the original design by Norwegian studio Salt Ship Design. She was subsequently transported to Hamburg, where additional modifications and outfitting were completed. The names of the new design team have yet to be confirmed.
Built for Exploration
O3 is curated for exploration and adventure. Her ice-classed hull, cargo-carrying capacity, and heli-hangar underscore her versatility. Constructed from steel and aluminium, the yacht is expected to feature over 6,000 GT and accommodate up to 20 guests in unparalleled luxury.

The yacht is powered by a diesel-electric propulsion system and incorporates cutting-edge energy-saving, power storage, and climate-control systems, according to Moran Yacht & Ship. These features will allow for efficient and sustainable operation while maintaining comfort on board.
Joining the Ranks of Mega Yachts
Once delivered, O3 will rank among the world’s largest superyachts. She joins at least 10 other 100m+ yachts currently under construction at Lürssen, including the 146.2-metre Project Defy, reinforcing the shipyard’s reputation for building some of the planet’s most extraordinary vessels.
The latest images of O3 show her in the final stages of preparation before trials, a glimpse of the immense scale, engineering, and luxury that define Lürssen’s work. Enthusiasts worldwide are now eagerly watching her journey toward completion.
