A milestone redefining what steel can become at Sanlorenzo, as it present project details of the first 74Steel, just ahead of its launch in La Spezia later on this year. At 74 metres and around 1,900 Gross Tonnage of volume 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. 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. The 74Steel has exterior lines by Zuccon International Project representing 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. Every line, volume, and 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. 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 cell technology that offer a combined 1.5 MWh capacity. 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. The Sun deck offers more al fresco dining with a bar/galley unit and commanding views from the highest point of the yacht. There is forward sofa seating arranged around a firepit and another hot tub flanked by sunpads, while the aft deck is devoted to sunbathing. Importantly, a transparent glass windbreak under the hardtop protects guests when the breeze picks up. At the heart of the 74Steel is the Owner’s Deck. This sanctuary of privacy and sophistication is spread over 130 square meters of interior space—and even more open-air deck space—that is devoted entirely to the owner’s needs. The suite comes with a private lounge and office; expansive walk-in wardrobe; two spa-inspired bathrooms, one with a stand-alone bathtub; and king-size bed overlooking a private forward terrace with hot tub. The aft deck is set up for secluded dining under the shade of the sundeck above. Strategic access points ensure that the owner can enjoy complete privacy, with staircases designed to prevent unwanted entry to the owner’s deck when desired. Thoughtful layouts also extend to the suite’s forward terrace, where the owner can enjoy uninterrupted views and outdoor relaxation in a space designed for both tranquillity and connection to the natural surroundings. The 56-sqm wheelhouse has been designed for maximum functionality and visibility. Equipped with an integrated bridge by Team Italia, now part of the Rolls-Royce group, it has a walk-around Portuguese bridge. The foredeck can be used as a touch-and-go helipad. In addition to the captain’s cabin, there is another suite for use by staff or a pilot. The sky lounge aft is divided into two distinct areas. The lounge proper functions primarily as a TV room with sliding glass doors on both sides. Folding glass panels can increase the footprint of this lounge to include a teak-decked interim space with direct access to the open aft deck, again through sliding glass doors, which is set up for “al fresco” dining veranda. Five ensuite guest suites—two twins, two doubles and a full-beam VIP—are located on the main deck. The VIP suite features its own living room that can be closed off from the sleeping area by sliding panels. A central corridor allows guest to walk straight from their cabins to the main saloon, which is set up both as a lounge area and as a cinema space with TV. Beyond and separated by a bar unit is a dining table able to seat up to 14 guests. Both lounge and dining areas—130 sqm in all—have sliding glass doors on both sides to increase contact with the outside environment and encourage a cooling sea breeze. Continuing aft, a double staircase provides direct access to the gym and spa on the lower deck. The open aft deck is dominated by a large glass-bottomed pool that illuminates the beach club below. The lower deck houses a pro-spec galley with a spacious crew dinette opposite. In the forward section are 11 crew cabins (the captain’s cabin is on the bridge deck) and a 12th cabin that can double as a hospital berth. Crucially, there are two dedicated crew stairs between the lower deck and the bridge deck, ensuring smooth, efficient and discreet service. Two tender garages amidships house a 10-metre Pascoe limo tender and the crew tender as well as a range water toys. The garages can be accessed from both the crew quarters and the engine room. A major feature of the 74Steel is its expansive beach club and wellness area, thanks to the more flexible layout options offered by the diesel-electric drive. The wellness area features a gym with fold-down platform, massage room, sauna, hammam plunge pool, and even a family room for younger guests. A transom door that cleverly folds flush into the swim platform and fold-down bulwarks allow the beach club to grow even larger when needed: a massive walk-around, exterior space when everything is deployed. The customisation options for this area are designed to cater to the owner’s personal tastes, whether that means more relaxation or entertainment areas. The tank deck is devoted to storage, crew accommodation and services. This includes cold/freezer room, dry stores, refrigerated garbage room, wine cellar, as well as a crew relaxation area and a crew gym—a specific request of the owner. The tank deck can be customised to provide more storage or additional crew areas, depending on what each owner requires. The first hull, for example, even has an area for hydroponic cultivation so the yacht can grow its own fresh vegetables. This soil-less method of growing plants uses mineral nutrient solutions to deliver water, nutrients, and oxygen directly to the plant roots. 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.
