Sanlorenzo 74Steel: the 74 metre flagship that sold three times before it touched water
Seventy four metres of steel and aluminium, a 130 square metre owner’s deck, and a beach club that opens to 290 square metres at sea level. Inside the Sanlorenzo 74Steel, the largest yacht the Italian yard has ever built, and the quiet strategy behind it.
Sanlorenzo did not build the 74Steel to win an argument about size. The Italian shipyard unveiled its 74 metre, roughly 1,900 gross ton flagship at La Spezia on 1 October 2025, and the number that matters most is not the length. It is three: the count of hulls already sold before the first one touched water, with a fourth under negotiation.
That figure landed in a market that has been expanding quietly underneath it. The global population of individuals worth more than thirty million dollars rose from 551,435 in 2021 to 713,626 in 2026, a 29 percent increase in five years, according to Knight Frank’s Wealth Report 2026. That is roughly 89 people crossing the threshold every single day.
So the Sanlorenzo 74Steel arrives as a test rather than a trophy. The yard spent sixty seven years perfecting restraint at smaller scales. The question this yacht asks is whether restraint survives at 74 metres.

Why does the Sanlorenzo 74Steel stop just short of gigayacht?
At around 1,900 gross tons, the yacht sits deliberately under the 2,000 GT line that separates a superyacht from a gigayacht. Sanlorenzo treats that ceiling as a hard internal limit, avoiding the production complexity and resale friction that come with genuinely enormous hulls. It is a brand decision dressed as an engineering one.
“This is our most ambitious project,” said Massimo Perotti, Chairman and CEO of the Sanlorenzo group. “It marks a new pinnacle in our steel range, but the 74Steel is more than just our largest yacht; it’s a statement of our values.” The platform underneath it is pre engineered to 72 metres LOA, which lets each hull vary slightly in final length depending on its bow. The first two units run diesel electric propulsion. The third uses a conventional in line shaft.
That flexibility is the actual product. Buyers at this level are not choosing from a catalogue; they are co authoring a hull. “Each of the three hulls in this series to date is a true reflection of bespoke design,” said Tommaso Vincenzi, CEO of Sanlorenzo. “The owners have worked closely with us, almost co authoring their yacht, allowing for an unprecedented level of customization. These are not just yachts, they’re expressions of individuality.” Three owners, one engineering base, three different answers.


Inside the owner’s deck: 130 square metres of private architecture
The exterior lines of the Sanlorenzo 74Steel belong to Zuccon International Project, the Rome studio that has shaped the yard’s silhouette for years. “This project marks a decisive change of scale in floating architecture,” said architect Bernardo Zuccon, describing the work as an exploration of machines à habiter. On the first hull that translates to a vertical bow and a dynamic stern, drawn to sharpen both the profile and the way the yacht meets the water.
Inside, Francesco Paszkowski worked with Margherita Casprini on a layout built outward from the owner rather than inward from the hull. The owner’s deck runs 130 square metres of interior space, plus open air deck beyond it, and belongs entirely to one suite: a private lounge and office, a walk in wardrobe, two spa bathrooms including one with a freestanding tub, and a king bed facing a forward terrace with its own hot tub.
The privacy is structural, not decorative. Staircases are routed specifically to prevent unwanted access to that deck. Casprini’s materials carry the same discipline: matte wood finishes throughout, with every ensuite bathroom finished in a different marble whose colour and texture reappear in the artwork nearby.

One deck below, five ensuite guest suites share the main deck
One deck below, five ensuite guest suites share the main deck: two twins, two doubles, and a full beam VIP with a living room that closes off from the sleeping area. A central corridor delivers guests straight into a saloon that doubles as a cinema, then past a bar unit to a dining table seating fourteen. Lounge and dining together occupy 130 square metres, with sliding glass on both sides.
Higher up, the yacht relaxes. The bridge deck holds a 56 square metre wheelhouse with an integrated system from Team Italia, now part of the Rolls Royce group, and a foredeck engineered as a touch and go helipad. The sky lounge behind it opens through folding glass panels onto a teak veranda. On the sun deck, sofa seating wraps a firepit, a second hot tub sits flanked by sunpads, and a transparent windbreak under the hardtop keeps dinner civilised when the breeze arrives.


So how much does a Sanlorenzo 74Steel actually cost?
Sanlorenzo has not published a price, and no honest figure exists for a yacht where every hull is a separate commission with its own interiors, layout and bow. What does exist is market context. In the first half of 2025 alone, Burgess reported USD 1.4 billion in completed sales and represented 63 percent of all 70 metre plus transactions by value. The 74Steel sits at the top of exactly that bracket.
The more useful question is what ownership at this scale actually involves. A yacht of roughly 1,900 gross tons carries twelve crew cabins, which means a permanent payroll before the yacht leaves the dock. It carries two tender garages, a wellness deck and a hydroponic garden, all of which need maintaining. Buyers commissioning at 74 metres are not comparing sticker prices. They are committing to a decade long operating relationship with a yard, which is precisely why three of them signed before seeing the finished boat.

Sanlorenzo 74Steel, first hull
The most consequential decision on board is invisible from any deck. The first hull runs diesel electric propulsion engineered in house with Siemens Energy: six variable speed Volvo Penta and MASE generators driving twin Schottel E Pods of 1,000kW each, backed by a water cooled LEHMANN COBRA battery system using lithium iron phosphate cells with 1.5 MWh of combined capacity. Freeing the hull from a conventional shaft line released volume that would otherwise be machinery.
Sanlorenzo spent that volume on water level living. The Sanlorenzo 74Steel beach club opens to roughly 290 square metres once the transom door folds flush into the swim platform and the bulwarks drop. Above it sits a glass bottomed pool that lights the space from the main deck. The wellness area carries a gym with a fold down platform, massage room, sauna, hammam and plunge pool. Eleven crew cabins sit forward on the lower deck, with a twelfth convertible to a hospital berth, and two dedicated crew stairwells keep service out of sight. Two tender garages amidships hold a 10 metre Pascoe limo tender alongside the crew tender. On the tank deck, the first owner asked for something no spec sheet predicts: a hydroponic garden, so the yacht grows its own vegetables at sea.

Explore SanlorenzoWhy it matters
The strategic asset in the Sanlorenzo 74Steel launch is not the 74 metres. It is the pre engineered platform sold three times as three different yachts, each with its own bow, its own interior and, in one case, an entirely different propulsion architecture. With the ultra wealthy population growing by 162,191 people in five years, the constraint on high ticket luxury is rarely demand. It is the ability to deliver real personalisation at production speed. Sanlorenzo engineered the platform once and sold the customisation. Every heritage brand climbing into a new price tier should be taking notes.
