The EVO 31 marks a confident step in Antonini Navi’s custom line-up, a 31.2-metre full-custom displacement yacht built in steel and aluminium at the yard’s La Spezia facility. Designed by Hydro Tec with interiors by Hot Lab, the EVO 31 carries the crossover philosophy that defines the Italian builder, pairing explorer-grade range with the proportions and finish of a contemporary superyacht. Twin Caterpillar C18 engines give a relaxed 12-knot cruise and a 4,000-nautical-mile range at 10 knots, the signature of a hull conceived for genuine long-distance cruising rather than headline speed. Accommodation is arranged for ten guests, with generous volume held under 300 gross tons to preserve flexibility of operation and berthing. The EVO 31 is currently in construction, and like every Antonini Navi yacht it is delivered through the yard’s Blue Mile Protocol, a build and sea-trial discipline underpinned by seventy years of metalworking heritage. For an owner seeking a bespoke, go-anywhere yacht in the 30-metre class, the EVO 31 offers the rare combination of true custom design and a displacement platform engineered for comfort at sea. The Yacht Collection can introduce you to this model and guide a new-build or resale enquiry from first conversation through to delivery.

Twin Caterpillar C18 engines, each rated 533 kW, drive the EVO 31 to a maximum of 13 knots and a comfortable 12-knot cruise. The displacement hull is tuned for efficiency rather than speed, returning a 4,000-nautical-mile range at 10 knots. That reach places genuine ocean passages within scope, from the Mediterranean to the Atlantic islands and beyond, with the fuel capacity and seakeeping expected of a true long-range yacht.
Hydro Tec gives the EVO 31 clean, purposeful lines, uniting the superstructure and sun deck into a single flowing form. Large side openings, broad walkways and a generous beam of 7.5 metres create protected outdoor living across multiple levels. The crossover stance, upright bow and balanced volumes read as contemporary without chasing fashion, a profile intended to age gracefully across a long ownership.
Interiors by Hot Lab accommodate ten guests in a layout that can be tailored to the owner’s brief, the advantage of a genuinely custom build. Full-height glazing draws daylight deep into the saloon, while the sub-300-ton volume is used to deliver cabin sizes and ceiling heights more often found on larger yachts. Materials, joinery and layout are specified individually for each hull.
The crossover concept frees deck space usually lost to machinery and tankage on faster hulls. Owners gain expansive sunbathing and dining areas, a sheltered main-deck cockpit and a sun deck that spans the full beam. The result is a yacht that feels larger than its 31 metres, equally suited to quiet anchorages and extended cruising with family and guests aboard.
Built at Antonini Navi’s La Spezia yard under its Blue Mile Protocol, the EVO 31 draws on seventy years of metalworking heritage. Construction in steel and aluminium gives strength and longevity for ocean use, and every system is specified to the owner’s cruising plans. The model is currently in build; The Yacht Collection can arrange introductions, viewings and full support through specification and delivery.
