Sanlorenzo 74Steel: A flagship where strength becomes serenity, scale creates space, and structure meets soul
At 74 metres and around 1,900 GT, the new flagship becomes an instant icon of the Italian Maison, delivering the advanced technology, bespoke personalisation, and discreet grace for which Sanlorenzo yachts are renowned, but on a new and ambitious scale.
“From a brand perspective, this is a pivotal moment for Sanlorenzo”, says Massimo Perotti, Chairman and CEO of the Sanlorenzo group. “This is our most ambitious project and it marks a new pinnacle in our steel range, but the 74Steel is more than just our largest yacht; it’s a statement of our values — representing elegance, restraint, and the purity of living life at sea—the core values of Sanlorenzo.”
“With the 74Steel, we’re challenging the idea that size equals excess. We’re demonstrating that we can apply the same refinement and precision you’d expect from Sanlorenzo, even in this new, larger category. This is not just about size — It’s about philosophy.”
Developed on a pre-engineered technical platform, the 74Steel provides innovation and uncompromising design in abundance, becoming the new flagship for the yard. It embodies Sanlorenzo’s time-honoured commitment to craftsmanship, innovation and made-to-measure yachting, enabling owners to shape their vessel into an intimately personal work of art without compromising structural integrity or engineering excellence.
With three hulls sold and a fourth under negotiation before the first even touches the water, the owners of subsequent launches have curated unique interiors, customised layouts, and even different bow configurations. Although the platform is engineered to 72 meters LOA, all the current orders are of slightly different length depending on the bow shape. Moreover, the first two units have a diesel-electric propulsion system, the third has conventional in line shaft-propulsion. This flexible approach ensures that each yacht can evolve with the owner’s needs, while maintaining a tried-and-tested framework.
“We’re offering our clients a yacht that feels fully customised without losing the reliability of a proven platform and the aesthetic that makes a Sanlorenzo recognizable everywhere“, explains Tommaso Vincenzi, CEO of Sanlorenzo. “Each of the three hulls in this series to date is a true reflection of bespoke design. The owners have worked closely with us, almost co-authoring their yacht, allowing for an unprecedented level of customization. These are not just yachts — they’re expressions of individuality.”
Exterior Design: Architectural calm on an unprecedented scale
The exterior lines by Zuccon International Project represent a bold evolution of the design language the Rome-based studio has brought to Sanlorenzo, merging sinuous, soft forms with strength and elegance in timeless harmony. Key elements, such as the vertical bow and dynamic stern for the first unit, enhance both the yacht’s aesthetic and its functional relationship with the sea.
“This project marks a decisive change of scale in floating architecture”, says Bernardo Zuccon, Architect. “The exterior design is the outcome of an extensive process of stylistic research, through which we embraced a dimension never before explored by the shipyard – a true expression of machines à habiter, to quote the famous words of Le Corbusier.”
Interior Design: An owner-centric approach, designed from the inside-out
Every line, every volume, and every spatial transition was crafted with the owner’s experience in mind. From the dedicated owner’s deck to light-filled salons and seamless sightlines, architecture defines the way life unfolds onboard.
The interior design of the first unit, by Francesco Paszkowski in collaboration with Margherita Casprini, reflects the sculpted forms of the exterior. In particular, the furniture pieces are characterised by pronounced curves, and the design is complemented by rugs with sinuous shapes that help define spaces in a non-traditional manner.
“Each new project with Sanlorenzo is a source of great pride for us” says Francesco Paszkowski, Architect.
“The 74Steel marks another milestone in a long-standing collaboration that continues to evolve through increasingly ambitious undertakings. In this case, the owner placed particular emphasis on the interiors, and our work focused on translating those requests into spaces of refined elegance and functionality, while maintaining a constant dialogue with the stylistic codes and classic details that define Sanlorenzo’s identity”.
“The choice of materials, meticulously curated and elegantly refined, plays a crucial role in achieving the yacht’s warm and modern atmosphere”, adds Margherita Casprini. “The interiors are dominated by matte wood finishes, giving the yacht a natural, refined feel, while more eclectic materials bring vibrancy and uniqueness to the various spaces. Each ensuite bathroom, for example, features a different variety of marble with colours and textures that are carried through into the artwork on board.”
Technical Excellence
A key element of the first 74Steel is its diesel-electric system. This diesel-electric propulsion setup provides more freedom in terms of layout, making it possible to repurpose technical spaces for recreational areas. This is especially evident in the expansive beach club and spa areas, which are significantly larger than those on a conventional yacht of similar size.
Engineered in-house in collaboration with Siemens Energy to maximise efficiency while ensuring reliability, the propulsion system itself relies on six variable-speed Volvo Penta – Mase generators driving twin Schottel E-Pods of 1,000kW each. The hybrid setup includes water-cooled LEHMANN COBRA battery systems employing inherently safe lithium iron phosphate (LFP) cell technology that offer a combined 1.5 MWh capacity.
“With redundancy built into both the power and propulsion systems, owners can enjoy peace of mind knowing the yacht’s essential functions remain unaffected in case of any failure”, says Giovanni Bizzarri, New Product Development Executive Director.
In addition, the yacht’s HVAC system utilises Variable Air Volume (VAV) technology to regulate the amount of conditioned air delivered to different zones based on real-time temperature and occupancy needs, providing optimal air circulation and precise temperature control. This advanced system guarantees maximum comfort, energy efficiency, and a quiet, peaceful environment throughout the yacht.
At around 1,900 gross tons, the 74Steel sits at the upper limit of Sanlorenzo’s size range. This is driven by a mix of strategic considerations and production capacity. By limiting its focus to yachts below 2,000GT, Sanlorenzo avoids the risks associated with building “gigayachts”, which become increasingly difficult to manage in terms of both market appeal and production complexity.
74Steel is more than a flagship — it is a landmark in Sanlorenzo’s evolution. With its blend of architectural purity, advanced technology, and unprecedented personalisation, it reflects not only where Sanlorenzo stands today, but where it is going. From steel to sustainability, from scale to soul, the 74Steel embodies a future in which innovation and elegance remain inseparable.
