The 54.83m Riva flagship uses exceptional marble, warm teak and open terraces to create an indoor-outdoor design at under 500 GT.
Riva 54Metri brings the Italian builder’s distinctive treatment of materials into a considerably larger space. The 54.83-metre all-aluminium flagship, which appeared at Monaco in September 2026, pairs rich marble and natural teak with full-height windows and fold-out bulwarks that let the beach area open towards the sea.
Material choices with a clear identity
Riva’s official release identifies Sahara Noir marble from Tunisia and Bianco Rhino marble from Africa, set against natural teak and leather details. Rather than using the same material everywhere, the interior plays with contrast and warm touches to create different moods across the guest rooms.
The finish choices express the design direction of a specific flagship commission, and the published photographs should not be taken as proof of the exact materials in any future sistership. Officina Italiana Design, founded by Mauro Micheli and Sergio Beretta, developed the exterior and interior with Ferretti Group’s design and engineering teams.
Openings that bring the water closer
Fold-out bulwarks extend the cockpit and beach areas, turning the protected aft deck into more generous sea-facing terraces when the yacht is stationary. Full-height windows provide the interior with broad views even before those openings are deployed.
Together, these features soften the division between a formal saloon and an exterior room. Their use requires appropriate sea conditions and crew operation, not an assumption that the sides can remain open during every passage.
Under 500 GT, over 54 metres
The specification records 499 GT, approximately 9.18 metres of beam and an 18-knot top speed from twin MTU 12V2000-M96L engines. The yacht is therefore an unusually large Riva while remaining inside the under-500 GT design envelope.
The performance figures belong to the manufacturer’s published particulars and do not establish the result of any independent speed trial. Final loading and the captain’s route planning affect practical passage speeds.
An Italian yard at a new scale
The flagship was built at Riva’s Superyacht Division in Ancona, marking a step beyond the size of earlier Riva ranges. It reflects a consistent brand identity in a new category rather than an attempt to disguise itself as another yard’s custom project.
This feature examines the documented materials and guest areas, separately from SYG’s previous account of the Monaco debut. A unique official 54Metri photograph is used, not a duplicate from the earlier show report.
