M/Y O3 ex. SHACKLETON 109m Explore Yacht by Lürssen Yachts 🇩🇪

Lürssen 110m Explorer Superyacht – O3 (ex-Project Shackleton / Icecap) – Latest Update 🚢❄️

As of February 2026, the highly secretive 110-metre Lürssen superyacht O3 is actively undergoing sea trials in Danish waters (North Sea region) after departing German shipyards. Spotted with her name prominently displayed, this marks the final testing phase ahead of imminent delivery in Q1 2026 (spring expected). Construction spanned nearly 8 years (started 2018), making O3 one of Lürssen’s longest and most closely guarded builds. 🌍🇩🇪

Ownership & Context 👑 Owned by Ukraine-born US/British billionaire Len Blavatnik (Access Industries founder; net worth est. $30–32B+). Blavatnik diversified from post-Soviet Russian investments into chemicals (LyondellBasell), oil, aluminum, media (Warner Music Group), real estate, & entertainment. O3 succeeds his prior Lürssen Northern Star (76m, 2009; sold 2021 as Bella Vita). The name O3 may reference his fleet (e.g., linked to Odessa II). Build value est. ~$350M; annual running costs ~$25–35M.

Standout Features

• Massive volume for lavish guest/crew spaces, wellness centre (spa, gym), cinema, gourmet dining (indoor/outdoor), beach club potential.
• Eco-conscious: Hybrid propulsion, large battery banks, efficient systems.
• Built alongside naval vessels at Peene-Werft → exceptional durability & engineering.
• Aligns with rising demand for capable explorer superyachts.

O3 stands as a pinnacle of Lürssen craftsmanship: extreme capability, discreet luxury, & go-anywhere pedigree. With sea trials progressing, she’s set to redefine expedition yachting upon delivery.
