Sanlorenzo 58Steel For Sale

Sanlorenzo 58Steel is a 58-metre superyacht in build at Sanlorenzo, and a landmark model for the Italian shipyard: the first in its celebrated Steel line to introduce an all-new diesel-electric hybrid propulsion system. A refined and extended successor to the acclaimed 57Steel, she reimagines the use of onboard space within the 55-to-60-metre segment, offering interior volumes comparable to those of a 64-metre yacht. She is offered ahead of delivery in 2029.

Her exterior is the work of Zuccon International Project, the Roman studio behind the entire Steel family. The design language is one of timeless proportion and architectural definition, its sculptural surfaces expressing Sanlorenzo’s conviction that steel is a material of balance and innovation rather than excess. The bridge deck has been extended by a metre to enhance both aesthetics and function, while at the stern a three-sided beach club opens to the sea as one of the yacht’s defining statements, a luminous retreat that turns engineering precision into pure wellbeing.

At the heart of the yacht is that revolutionary propulsion package. Built around five 425 kW generators and a one-megawatt-hour battery pack, with azimuthal pods for improved manoeuvrability and reduced noise and vibration, the diesel-electric system reduces emissions by around ten per cent compared with a conventional arrangement and enables up to two hours of silent cruising or up to eight hours of zero-emission hotel operation at anchor. Crucially, re-engineering the entire engine room onto a single deck has freed more than forty square metres of additional space, repurposed to expand the guest accommodation and beach areas.

Inside, the Sanlorenzo Style Department has crafted an interior of understated luxury, combining dark woods with Calacatta Borghini marble, mother-of-pearl and champagne-toned finishes in a warm, tactile palette. Every element is custom-designed in line with the yard’s made-to-measure philosophy. Two full-beam VIP cabins on the lower deck draw natural light through panoramic windows, while a Supreme VIP on the main deck rivals an owner’s suite for comfort and privacy. Above, the owner’s deck becomes a private residence suspended over the sea, complete with panoramic suite, pool, office and full-height glazing, while the main-deck lounge opens seamlessly onto an infinity pool.

Constructed in steel and aluminium to approximately 1,165 gross tons, with an expanded 11.25-metre beam and a shallow 2.8-metre draught that broadens her choice of anchorage, the 58Steel is engineered for silent, sustainable cruising at a top speed of around 15 knots. She accommodates her guests in generous, light-filled suites with a crew of up to thirteen.

Representing evolution rather than repetition, the 58Steel marks a decisive step forward for Sanlorenzo’s steel range and for sustainable cruising in her class. Contact The Yacht Collection to explore this 58-metre Sanlorenzo opportunity in full.

As the model that brings diesel-electric propulsion to Sanlorenzo’s steel range for the first time, the 58Steel also carries a particular significance. It signals a clear direction for the yard’s future builds, placing sustainability and spatial innovation at the heart of the design without compromising the elegance and restraint that define the brand. For an owner who values quiet, efficient cruising and a deep connection to the sea, she offers a genuinely forward-looking proposition from one of Italy’s most respected builders.
