Numptia

Numptia was the yacht that announced Rossinavi to the wider market, a 70 metre flagship launched in Viareggio in 2011 under the family's own name. Tommaso Spadolini drew her exterior and Achille Salvagni shaped the interior, giving the yard's first true giant a confident and timeless presence. She has since sailed as High Power III, yet her build remains a landmark in the yard's history.

The yacht that carried the family name

For decades the Rossi family had built steel and aluminium hulls for other Italian yards, working quietly as the metalwork behind other people's brochures. When the Rossinavi name first went on a transom in 2007, the family needed a project big enough to prove they could deliver a full size flagship. Numptia became that proof. At 70 metres she was among the largest yachts the Viareggio yard had ever attempted. Her keel marked a real leap in ambition for a builder long used to supplying others.

Her scale mattered as much as her styling. A 70 metre displacement yacht asks for real engineering discipline in the hull, the systems and the finish, and Numptia showed the yard could hold that standard across three decks. For an owner she was early evidence that a young marque could stand beside far older names on the same dock. The build set the ambition for the larger Rossinavi yachts that followed through the decade. Completing her to this standard gave the yard a confidence it has carried ever since.

Spadolini's measured hand

Tommaso Spadolini gave Numptia a classic exterior with balanced proportions and a profile that has aged gracefully. The long foredeck, the gentle sheer and the generous glazing were drawn to flatter the yacht at anchor and underway. Spadolini avoided of-the-moment gestures, so the result still looks composed more than a decade after her launch. The styling carries the quiet authority that owners associate with a serious 70 metre. Owners drawn to enduring design still find very little to argue with in her face.

The exterior also earns its keep as usable space. Wide side decks, a broad sundeck and sheltered aft areas give guests room to spread out without crowding. Numptia was drawn for long stays aboard in warm cruising grounds, and the deck plan reflects that ambition. In an anchorage her presence is understated for her size. The proportions were judged by an eye with decades of Italian yachts behind it.

Salvagni's warm interior

Achille Salvagni handled the interior, and his blend of soft materials and sculptural detail suited a yacht of this scale. The volumes are generous, with high ceilings and long sightlines that make 70 metres feel domestic and calm. Warm woods, bronze tones and considered lighting give the rooms a sense of permanence. The main saloon and dining areas were arranged for both large gatherings and quiet evenings. The craftsmanship gives the rooms the settled feel of a fine town house.

Accommodation follows the pattern owners expect of a flagship from this era, with a private owner's area and a spread of guest suites served by a substantial crew. The layout keeps guest and service circulation apart, so the yacht runs smoothly during long charters or family holidays. Salvagni's interior has proved durable in taste, which matters on a yacht that has since changed hands and names. It remains one of the yard's most quietly elegant early rooms. Little about the finish betrays the age of the yacht around it.

Built for distance

Numptia is a full displacement yacht, engineered for comfortable passages at sensible speed and long range between fuel stops. That character makes her a genuine cruiser for owners who want to move between grounds under their own keel. The hull and systems were built to the commercial grade discipline the Rossi family had learned as a subcontractor. Reliability was designed in from the first frames. Owners who cruise seriously value that unhurried and long-legged temperament.

For her period she was a bold statement of the yard's engineering reach. A 70 metre steel hull was a considerable undertaking for a marque only a few years old under its own name. That experience fed directly into the larger and more complex Rossinavi projects that came after. Numptia proved the yard could carry a giant from lofting through to sea trials. The lessons learned on her hull shaped every larger Rossinavi that came after.

Who she suits

Numptia suits an owner who values provenance and a timeless line, and who wants a proven 70 metre with a clear place in a builder's story. She rewards long cruises with family and guests, offering the volume and the range for extended time aboard. Her later career as High Power III shows she has held her appeal across ownerships. She is a flagship with real history attached. She carries the weight of a genuine first chapter wherever she cruises.

For a buyer studying the Rossinavi fleet, she is the origin point of the yard's big yacht ambition. Owning her means owning the yacht that first put the family name on the map. That kind of narrative is rare and hard to manufacture. It travels with the yacht wherever she cruises. Few yachts in her class offer a story this clearly written into the marque.

Engines and systems

EnginesTwin Caterpillar 3516B DITA-SCAC. Reported power varies by source, from about 2,200 hp to roughly 3,400 hp (2,525 kW) per engine, which most likely reflects a continuous-versus-intermittent duty rating rather than two different engines; confirm the fitted rating from the class certificate rather than a brochure.
Speed15 to 16 knots cruise, 18 to 18.6 knots maximum depending on source.
Fuel and water200,000 litres of fuel and 40,000 litres of fresh water, consistent across every source checked.
HullSteel hull with aluminium superstructure and teak decks, full displacement form.
Vertical accessA glass elevator runs from the lower deck to the spa deck, unusual equipment for a yacht of her build year.
Generators, stabilisers, thrustersNot published in any source checked; ask the broker for the class documentation if these matter to a purchase decision.

What is good, and what to watch

Strong points

  • Genuine ocean range7,500 nautical miles at 12 knots from a 200,000-litre tank, enough to cross an ocean without refuelling.
  • A full-beam master suite with real amenityHis-and-hers dressing rooms, a curved marble bath with two rainforest showers, and a glass elevator running lower deck to spa deck, features that were unusual on a 2011 hull and still read well now.
  • Styling that has not datedTommaso Spadolini's exterior avoided of-the-moment styling gestures, which is a large part of why the yacht still presents well fifteen years after delivery.
  • A landmark build for the yardShe was Rossinavi's first true flagship-scale project and set the engineering standard the yard's later giants were built on.

What to watch

  • A 2011 engine and systems generationTwin Caterpillar 3516B diesels at a modest 18-knot top speed and 15 to 16-knot cruise; a buyer comparing her to a modern diesel-electric hull of similar size should expect higher fuel burn per mile.
  • Renamed and resoldShe has sailed as Numptia and now as High Power III; that is not unusual for a yacht this age, but it means the ownership and maintenance record is split across two names in most databases.
  • No independent usage recordEverything public is brokerage or charter copy; there is no owner or crew account to weigh against it.

Practical detail

Charter statusListed by several brokers as available to charter under the name High Power III, though YachtCharterFleet shows her currently unavailable; rates are quoted on application rather than published, which is normal at this size.
Last refit2025, per YachtCharterFleet. No public breakdown of what the refit covered was found; ask the broker whether it touched the engines, the interior, or both before treating the yacht as mechanically current.
Crew18 to 19 depending on source, across dedicated crew cabins separate from the guest accommodation.
Built and classedRossinavi, Viareggio. Lloyd's Register 100 A1 SSC Yacht (P) MONO G6 LMC UMS, MCA LY2 compliant.
What is not publishedNo independent owner or charter-guest account of the yacht was found in open sources; everything available is brokerage and charter-marketing copy, which this page treats as such rather than as reader testimony.
What to check on this oneBrokerage specification sheets disagree on beam (12.3m versus 13.2m) and gross tonnage (1,410 versus 1,642 GT) for the same hull, which usually means a listing has not been updated since a refit, or is simply wrong. Confirm both from the current registry document rather than any single brochure.
