March 28 saw the launch of this 34-metre full-custom steel superyacht that showcases the brand’s tailor-made philosophy and is eagerly awaited at the upcoming boat shows 2026.
Antonini Navi celebrates the launch of the Seamore 34, the first yacht built at its La Spezia yard. This significant milestone marks the brand’s entry into the steel superyacht segment under 500 GT, a highly competitive market dominated by major Italian and Northern European shipyards. The launch of the Seamore 34 is a growth milestone for the shipyard, which is rapidly establishing its credentials as a new player with industry experts and owners interested in custom steel yachts. With a second unit already nearing launch and a third at a stage of construction, taken together with the development of new projects in partnership with international design firms – including Nauta Design, Fulvio De Simoni Yacht Design and Hot Lab – Antonini Navi is now a force to be reckoned with on the international yachting scene. The launch ceremony – a private event attended by the owner and his family – included the traditional blessing of the yacht, marking a highly symbolic moment for the whole team at the shipyard.
The Seamore 34 marks the launch of what will become a semi-custom line for the shipyard, as well as reflecting Antonini Navi’s approach to design: a robust and well-engineered steel and aluminium platform developed to offer new customers broad freedom in terms of customisation and configuration. The project concept was developed in-house by Antonini Navi, while the interiors are by well-known Milan-based firm Hot Lab. A distinctive feature of the boat is the layout, which prioritises continuity between indoor and outdoor spaces. On the main deck, over 150 square metres of living space stretch seamlessly from stern to bow, with large sliding glass panels used to adapt the spaces as required. There are also about 160 square metres of outdoor space on the upper deck, designed to provide an active and convivial experience on board. The interiors feature a design language that skilfully combines classic and contemporary elements, creating an elegant but understated setting. The palette of materials is made up of fine finishings featuring ribbed textures, antiqued glass surfaces and panelling lacquered in pastel colours, chosen to modulate the light and amplify the sense of space.
The interplay between materials, colours and finishes creates a consistent and harmonious whole, in which every element contributes to a relaxed and sophisticated mood, perfectly in tune with the maritime setting and a casual yet sophisticated lifestyle on board. Antonini Navi forms part of Gruppo Antonini, the storied industrial enterprise based in La Spezia since 1943, which brings to the yachting world its proven expertise in the construction of commercial structures and offshore and onshore platforms for the oil & gas industries. This heritage of experience has resulted in robust production capacity and an industrial and engineering approach that combines tradition and craftsmanship in both steelworking and fitting out.
“The launch of the Seamore 34 achieves a significant milestone for our family on a journey we began several years ago, one that was strongly backed by myself and my son Walter, who is now the shipyard’s General Director. Antonini Navi is the tangible manifestation of our ability to turn a vision into a real product. Construction has always been part of our DNA, and this will continue into the future,” said Simone Antonini, the shipyard’s founder and CEO.
Co-founder and sales manager Aldo Manna added: “The Seamore 34 is the concrete embodiment of our approach to full-custom yachts: the ability to develop every product from a blank sheet, supported by a solid, well-organized technical office, and by a problem-solving mindset focused on the sole goal of the owner’s full satisfaction. This yacht has been designed to be reliable, functional and fully adaptable to the customer’s needs, without compromising on performance and build quality. At the same time, it showcases the skill and organization of our production department, which has successfully translated the design into a beautifully built, high-quality yacht. The launch of the Seamore 34, the first yacht designed and built by Antonini Navi, marks our entry into a highly competitive segment, where we have positioned ourselves as a credible and capable alternative to other steel yacht builders working in this category.”
The Seamore 34 will be on display at the upcoming 2026 boat shows where, to an international audience, Antonini Navi will present the first model in a range it is planning to develop in the coming years.
