a 64-metres yacht. Every aspect has been conceived with flexibility and personalisation in mind, offering an on board experience tailored entirely around the owner’s lifestyle.
Expansive volumes and customisable layouts deliver the comfort of a larger yacht, with two full-beam VIP cabins on the Lower deck and a Supreme VIP on the Main deck. The Upper deck transforms into a secluded owner’s sanctuary: a panoramic suite with pool, office, dressing area, and a lounge convertible into a private cinema – the perfect configuration also for charter purposes.
At the stern, the beach club opens on three sides to create a floating terrace, complete with bar, hammam, gym, and beauty salon — a space designed for connection to the sea through light, silence and simplicity.
A silent revolution: diesel-electric propulsion
At the heart of the 58Steel lies a revolutionary diesel-electric propulsion system, the first of its kind in Sanlorenzo’s steel line.
This new configuration marks a decisive step towards sustainability, reducing emissions by around 10% compared with conventional propulsion and enabling up to two hours of silent cruising or up to eight hours of zero-emissions hotel operation while at anchor.
The system is based on five 425 kW generators and a 1 MWh capacity battery pack. Its modular design enhances efficiency and flexibility, while azimuthal pods with rotating propellers improve manoeuvrability and reduce vibration and noise.
The entire engine room has been re-engineered to occupy a single deck, freeing up more than 40m² of additional space — a remarkable achievement that has been repurposed to expand the guest and beach areas.
“This yacht represents evolution, not repetition. With its diesel-electric propulsion system at the core, the 58Steel unlocks new horizons of freedom: more space, more light, greater efficiency and a profound connection to the sea.” says Tommaso Vincenzi, CEO of Sanlorenzo.
“Each detail reflects our time-honoured DNA — elegance, restraint and experiential purity — reaffirming our commitment to meaningful innovation in harmony with design.”
Interiors: the essence of made-to-measure
The interiors, crafted by Sanlorenzo’s Style Department, reflect a vision where engineering excellence meets design purity. A warm, tactile colour palette — combining dark woods with Calacatta Borghini marble, mother-of-pearl, and champagne-finished accents create a sense of understated luxury.
Every element has been custom designed in line with Sanlorenzo’s made-to-measure philosophy, transforming space into a narrative of balance and proportion.
Two full-beam VIP cabins on the Lower deck offer natural light through panoramic windows, while the Supreme VIP on the Main deck rivals the comfort and privacy of an owner’s suite.
The Main deck lounge opens seamlessly onto an infinity pool, creating an unbroken dialogue between interior and exterior spaces. Above, the Owner’s deck becomes a private residence suspended over the sea, complete with spa bathroom and full-height glazing that dissolves the boundary between interior and horizon.
Exteriors: a sculptural expression of strength and serenity
The exterior lines of 58Steel reflect a language of timeless proportions and architectural definition, a clear stylistic expression of the Roman studio. Its sculptural surfaces make Sanlorenzo’s approach to steel explicit: not as a material of excess, but of balance and innovation.
The Bridge deck, extended by one metre, has been redesigned to enhance both aesthetics and functionality, merging technology and artistry in equal measure.
At the stern, the three-sided beach club remains one of the yacht’s defining statements — a luminous retreat that transforms engineering precision into an experience of pure wellbeing.
A new chapter in steel
The first 58Steel – Perla Lunar, has been sold by Arcon Yachts, a brokerage company based in Monaco with over 25 years’ experience in superyacht sales.
As Sanlorenzo celebrates 15 years of leadership in steel yacht design, the launch of 58Steel reaffirms the brand’s pioneering role in redefining the 55 to 60 metres segment. It stands as a testament to a philosophy where innovation and elegance are inseparable — where technology serves emotion, and craftsmanship meets conscience.
Because at Sanlorenzo, the journey of steel is never finished — it continues to evolve.
About Sanlorenzo
For more than 60 years, Sanlorenzo has defined Italian excellence in yacht building, crafting custom-made motoryachts and superyachts that blend refined design, innovation, and advanced engineering. Founded in 1958, the shipyard is the world’s leading mono-brand builder of yachts over 24 metres. Since 2005, under the ownership and leadership of Massimo Perotti, Sanlorenzo has undergone extraordinary growth — expanding its portfolio, production capacity, and global prestige. In 2019, the company was listed on the Euronext STAR Milan, further cementing its role as a leader in luxury yachting. Sanlorenzo’s yacht and superyacht production spans six specialist shipyards across Italy, with models from 24 to over 70 metres in both composite and metal construction. The Group also includes Bluegame, below 24m — known for innovative crossover models — and the newly acquired Nautor Swan, a prestigious name in sailing and high-performance motor yachts. Design and architecture have always been core to Sanlorenzo’s identity, thanks to long-standing collaborations with world-renowned studios including Piero Lissoni, Patricia Urquiola, Dordoni Architetti, and others. This fusion of yacht engineering and interior design sets Sanlorenzo apart in the world of high-end nautical craftsmanship. Looking ahead, Sanlorenzo is leading the sector toward sustainable innovation. Its “Road to 2030” strategy includes pioneering efforts in low-impact propulsion, such as green methanol fuel cells and hydrogen-powered tenders, developed with partners like Siemens Energy, MAN and MTU. In 2024, Sanlorenzo marked two major milestones: the delivery of the first 50Steel superyacht equipped with an on board fuel cell system, and the launch of hydrogen-powered Bluegame tenders for the America’s Cup. This same year, the Group acquired Nautor Swan, and with Simpson Marine, it is strengthening its portfolio and commercial footprint across Asia and beyond. Through initiatives like the Fondazione Sanlorenzo and Sanlorenzo Arts, the brand continues to support culture, sustainability, and the sea — values brought to life with the opening of Casa Sanlorenzo in Venice, a new home for design and dialogue.
