Sanlorenzo unveils the first 58Steel
The 58Steel is a refined and extended successor to the acclaimed 57Steel. Featuring an all-new diesel-electric hybrid propulsion system and a reimagined concept of onboard space, 58Steel embodies the brand’s philosophy of elegance, proportion and innovation.
Sanlorenzo launched its first steel yacht in 2010. Today, the brand’s impressive steel line has become the most defined in the segment under 2,000 GT. Now, the new 58Steel, designed by Zuccon International Project for the exteriors, represents a further evolution of this legacy — one metre longer, yet infinitely more versatile. With a completely new platform, an expanded beam of 10.8 metres and the introduction of diesel-electric hybrid technology, enabling zero-emissions cruising, it unlocks greater space, efficiency and silence.
While drawing inspiration from the 57Steel design, 58Steel evolves it completely, offering interior volumes comparable to those of a 64-meter yacht.
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.
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.
At the heart of the 58Steel lies a revolutionary diesel-electric propulsion system, the first of its kind in Sanlorenzo’s steel line.
According to the shipyard, this new configuration reduces emissions by around 10% compared with conventional propulsion and offers up to two hours of silent cruising or up to eight hours of zero-emissions hotel operation while at anchor.
The modular system is based on five 425 kW generators and a 1 MWh capacity battery pack. Azimuthal pods with rotating propellers improve manoeuvrability and reduce vibration and noise.
The entire engine room has been re-engineered, freeing up more than 40m² of additional space for guest accommodation and entertainment.
The interiors, crafted by Sanlorenzo’s Style Department, are characterised by a warm, tactile colour palette and combine dark woods with Calacatta Borghini marble, mother-of-pearl, and champagne-finished accents to create a sense of understated luxury.
