A ntonini Navi lifts the curtain on Light63M, a new 63-metre superyacht concept designed by Nauta Yachts, the Milanese studio known for some of the most iconic large yachts ever built. Developed in collaboration with Arrabito Naval Architects, the project distills the values that define both brands: balance, functionality, and a seamless relationship between interior spaces, exterior decks, light and sea.
The unveiling comes at a moment of strong momentum for Antonini Navi, which has experienced a notable rise in demand for vessels over 500 GT. That confidence from brokers and private owners reflects the yard’s solid industrial foundations and its growing presence among Europe’s new-generation large-yacht builders.
For the Light63M project, Antonini Navi chose Nauta for its unparalleled experience — the studio has designed more than 625 metres LOA and 27,000 GT of delivered superyachts, including global landmarks such as Azzam (180 m), Dragonfly (142 m) and Zen (88 m). With another 300 metres currently in build, Nauta brings a design DNA defined by purity, proportion and timeless restraint.
The result is a yacht conceived around fluidity and wellbeing on board.
Continuous architectural lines, carefully balanced solids and voids, and large glazed surfaces give Light63M an instantly recognisable profile — refined, open and destined to remain contemporary for decades.
Inside, the project emphasises Mediterranean modernity: natural materials, warm tones and light-coloured surfaces create a serene yet sophisticated atmosphere. Built-in architectural elements coexist with freestanding furniture, allowing each owner to tailor the ambience while preserving harmony and spatial clarity.
The layout prioritises discreet circulation, generous service areas and seamless guest-crew separation. Highlights include:
• A beach club and spa opening on three sides to the sea
• An owner’s apartment and VIP cabin with private outdoor terraces
• A panoramic gym with light entering from three directions
• A sun deck conceived as a private observatory facing the horizon
With a length of 63.5 m, a beam of 10.9 m and approximately 1,180 GT, Project Light63M is engineered for balance, efficiency and long-term reliability — a technically matured platform shaped through rigorous validation.
The announcement comes as Antonini Navi progresses on three major builds: Seamore 34, the first model of its semi-custom line; EVO 31, a full-custom project; and SUY 135, the inaugural unit of the yard’s new Sports Utility Yachts range.
Light63M stands as a clear statement: the partnership between Antonini Navi and Nauta Yachts is shaping a new era of elegant, essential, future-minded design.
