Sanlorenzo has delivered the first 58Steel, Perla Lunar, with a second unit already in production. Featuring an overall length of 58.25m and an 11.25m beam, the new 1,165GT tri-deck has been described by the Italian shipyard as “a refined and extended successor to the acclaimed 57Steel”.

Zuccon International Project designed the exteriors of the 58Steel, which is based on a new platform with an expanded beam and includes diesel-electric hybrid technology that enables zero-emissions cruising.

Massimo Perotti, Sanlorenzo’s Executive Chairman, said: “The 58Steel embodies the belief of a superyacht that redefines proportion, privacy and performance, offering a new dimension of silent, sustainable cruising. It represents our ambition to remain the benchmark in yachts up to 2,000GT, with our expanded steel line now spanning six individual superyachts that set the standard for design and desirability.”

At the stern of the 58Steel, the beach club opens on three sides and includes a bar, hammam, gym and beauty salon. On the main deck, the aft cockpit is dominated by a large infinity pool, while the interior includes the main saloon and a ‘Supreme VIP’ suite. The lower deck includes two full-beam VIP cabins and two more guest cabins, and the crew quarters forward.

The forward part of the upper deck is dedicated to the owner and includes a panoramic, full-beam bedroom with full-height glazing facing a foredeck terrace with a pool. Other aspects of the owner’s area include an office, dressing area, spa bathroom and a lounge or saloon that can be converted into a private cinema.

The upper deck also includes an aft deck suitable for alfresco dining, while the sundeck includes open social areas aft and the wheelhouse.

Main-deck saloon

The yacht’s interiors, crafted by Sanlorenzo’s Style Department, feature a warm, tactile colour palette combining dark woods with Calacatta Borghini marble, mother-of-pearl, and champagne-finished accents.

The diesel-electric propulsion system is the first of its kind in Sanlorenzo’s steel line, enabling up to two hours of silent cruising or up to eight hours of zero-emissions hotel operations at anchor. The system is based on five 425kW generators and a 1MWh-capacity battery pack, while pods with rotating propellers improve manoeuvrability and reduce vibration and noise.

Upper-deck saloon

The entire engine room has been re-engineered to occupy a single deck, freeing up more than 40sqm of space to expand the guest and beach areas.

Tommaso Vincenzi, Sanlorenzo’s CEO, said: “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.”

Owner’s suite

The Italian shipyard launched its first metal superyacht, the 40Alloy, in 2010. Its current Superyacht collection includes the Alloy (44.5m), 500Exp (47m), 44X-Space, 50X-Space, 50Steel, 52Steel, 57Steel, 58Steel, 64Steel and 74Steel, with the launch of hull one of the flagship announced in early October.
