Sialia Yachts Reveals the Tech Behind Its Revolutionary Electric Drivetrain

The 70-meter Benetti superyacht Alfa has completed an extensive refit at Lusben, the refit division of Azimut|Benetti Group. Originally delivered in 2020, the full-custom yacht underwent a complete renovation coordinated by Ocean Independence, with interior design by Mark Berryman Design.The technical scope included full repainting of the hull and owner deck with advanced protective coatings, along with the mandatory five-year survey of all major systems. Engineers conducted thorough inspections and servicing of stabilizers, propulsion shafts, engines, and generators. Mechanical upgrades featured new software for the forward crane allowing independent arm control, redesigned bollards, and optimized stern platform fittings for improved tender operations. Crew areas received attention with complete overhauls of the side ladder, stern passerelle, and swim ladder.André Mahr (Ocean Independence), Gianni Paladino (Lusben), Simone Rotili (PM Lusben), Alessio Centelli (Head of site Lusben Livorno)For interior spaces, the UK-based Mark Berryman Design studio preserved Alfa's original elegance while introducing contemporary elements. The main deck now features custom sofas with integrated chessboards, marble-clad tables with built-in fire pits, and redesigned wall panels. The owner's suite received new cabinetry and finishes, while four new bars were installed throughout the yacht, including a teppanyaki station on the skydeck. A striking wine cellar now occupies the portside corridor, transforming a transitional space into a design feature. The galley was completely reconfigured with new equipment and improved workflow."The work on Alfa perfectly embodies our 'life cycle' philosophy," said Gianni Paladino, Commercial Director of Lusben. "Supporting a Benetti yacht from launch through refit demonstrates our commitment to long-term value preservation."Ocean Independence's Anton Foord noted: "This relaunch represents months of dedicated work by skilled professionals. The attention to detail and quality craftsmanship are evident throughout the yacht."Captain Simon Johnson, André Mahr (Ocean Independence), Alessio Celli (Head of site Livorno), Simone Rotili (PM Lusben)Following the refit, Alfa will be available for Mediterranean charter this summer at €700,000 per week.

Built for a repeat client, the steel-hulled vessel features ice-class reinforcement capable of navigating the Northwest Passage, with Bureau Veritas Young Ice 2 certification.Valor represents Feadship's most advanced hybrid propulsion system to date, combining four variable-speed generators with a massive 5.34MWh lithium-ion battery bank - five times the capacity of 2015's Savannah.
