There is a grand, breathless sense of freedom that comes with commanding the horizon, and SAIRU was masterfully engineered to capture it.
As the absolute flagship of Riva’s legendary new 54 Metri line, this 54.83-metre all-aluminium masterpiece stands proudly as the largest vessel ever constructed in the shipyard’s storied 184-year history. Launched into the elite Boatsters Black charter fleet, SAIRU represents a paradigm shift in haute-maritime engineering. Crafted in collaboration with the renowned Officina Italiana Design, her striking Moon Grey aluminium hull, punctuated by a deep London Grey deckhouse and signature aquamarine waterline stripe, effortlessly commands attention in any marina from Monaco to Nassau.
Yet, beneath this imposing, sculptural profile lies a secret weapon engineered for the modern charter connoisseur: a remarkably shallow 2.23-metre draft.
The Superyacht Paradox: Volume Without Compromise
For ultra-high-net-worth individuals (UHNWIs), booking a private mega-yacht charter has historically forced a frustrating compromise. If you choose a vessel with massive internal volume and elite tri-deck amenities, you inherit a deep draft that anchors you miles away from the world’s most breathtaking shallow waters. You are forced to look at the vibrant, turquoise sandbars of the Exumas or the hidden, rocky coves of the Balearic Islands through binoculars.
SAIRU effortlessly shatters this paradox. At a substantial 499 Gross Tons (GT), she delivers the expansive luxury footprint of a world-cruising displacement mega-yacht. Yet, thanks to advanced naval architecture and an all-aluminium build, her shallow draft allows her to glide directly into the exclusive, crystalline bays that other yachts of her stature must sail past.
Life Aboard the Riva 54 Metri Flagship
Life aboard SAIRU flows organically across four beautifully resolved decks, seamlessly connected by a state-of-the-art internal amidships elevator that ensures effortless transit for all guests.
The Ultimate Waterfront Oasis
The stern architecture of SAIRU introduces a masterclass in modern outdoor living. Her expanded beach club opens up to a sprawling 60-square-metre waterfront terrace when the dual fold-down bulwarks are deployed.
-
The Stern Pool: At its center sits a stunning 5-metre custom swimming pool finished in pristine white ceramic tiles. Uniquely engineered, the pool is designed to remain fully filled while underway, eliminating the need to drain and refill between short island-hopping passages.
-
The Glass-Enclosed Gym: Positioned directly adjacent to the water-level terraces, a high-performance, climate-controlled wellness gym equipped with premium running and biking machinery allows you to train with uninterrupted ocean views.
-
The Sun Deck: High above the waterline, the sun deck functions as an ultra-private sanctuary spanning over 100 square metres, anchored by a premium hydromassage jacuzzi, fully stocked exterior bar, and plush sun pads.
Cinematic Interiors Defined by "Quiet Luxury"
Inside SAIRU, Officina Italiana Design has curated an environment of profound tranquility, relying on high-contrast, sculptural materials rather than overt ornamentation.
The main salon is flooded with natural light via continuous sweeps of floor-to-ceiling glazing. Beneath your feet, natural teak panelling grounds the space, while architectural accents of ultra-rare Sahara Noir and Bianco Rhino marble add sharp, sophisticated luxury. To ensure absolute serenity, advanced acoustic insulation paired with four electric Naiad Dynamics stabilizer fins keep the interior whisper-quiet and perfectly level, whether running at top speed or resting at anchor.
With an exceptional professional crew of 12 catering to just 10 guests, SAIRU maintains an ultra-exclusive, near 1:1 service ratio. The guest and crew pathways are entirely separated within the layout, ensuring that world-class hospitality and bespoke culinary experiences materialize seamlessly without ever impeding your absolute privacy.
Structural Architecture & Performance Metrics
For yacht brokers and charterers analyzing performance metrics, SAIRU represents the pinnacle of modern transoceanic engineering, fully classified under Lloyd’s Register technical safety standards.
The flagship is built to a length overall (LOA) of 54.83 metres with a maximum beam of 9.18 metres, providing exceptional structural stability without crossing the 500 GT threshold. This critical volume boundary ensures simpler regulatory compliance while maximizing the usable luxury layout for the 10 guests on board.
Propulsion is delivered by twin MTU 12V 2000 M96L diesel engines. These powerplants allow SAIRU to reach an impressive top speed of 18 knots and cruise comfortably at 15 knots. For long-range repositioning, the yacht achieves an oceanic range of 3,600 nautical miles while cruising economically at 11 knots, utilizing highly optimized shaft lines and six-blade fixed-pitch propellers.
Guest accommodations are split across two dedicated zones. The main deck forward houses the spectacular full-beam master suite, complete with a private office, walk-in wardrobes, and an opulent marble ensuite with a hydro-massage shower. Below deck, accessed via the central elevator or a leather-wrapped teak staircase, lie four mirrored en-suite staterooms, two expansive VIP suites with queen beds and two double cabins ensuring premium luxury for every individual onboard.
The Ultimate Canvas for a Bespoke Escape
Whether you are planning a milestone family celebration, a multi-generational holiday, or a deeply restorative escape into the wild blue, SAIRU turns a week at sea into something profoundly personal. Driven by twin MTU power, she cruises effortlessly, ensuring that your transit between paradise destinations is swift, stable, and incomparably refined.
By choosing the flagship of the Boatsters Black fleet, you aren’t just chartering a yacht, you are commanding the premier expression of Italian maritime art.
