Rosetti 85M Expedition Embraces Commercially Proven Technologies

Newcomer Rosetti Superyachts is so serious about addressing serious cruising that its first yacht proposal focuses on unrestrained explorations. Termed the Rosetti 85M expedition supply vessel, she comes from teams with deep roots in both yachting as well as commercial engineering and construction.

As mentioned earlier this month, Rosetti Superyachts has experienced management. Fulvio Dodich, formerly with Sanlorenzo and the Ferretti Group, heads operations. Rosetti Superyachts itself is also a division of a longstanding commercial shipyard, Rosetti Marino. Much of its background involves vessels serving the gas and oil industry, which operate no matter the weather. Therefore, the yacht division draws partially on that experience. It’s focusing on expedition and traditional megayachts from 131 to 492 feet (40 and 150 meters). Furthermore, it’s focusing on “long-range supply vessels,” a.k.a. support or shadow yachts.

At 279 feet, the Rosetti 85M expedition bears contributions from a commercially capable partner. Rolls-Royce Marine designed the hull to keep decks dry as much as operate in varying conditions. Note the marked bow flair in the images here, for example. Note, too, that the foredeck is 41 feet (12.5 meters) high. Rolls-Royce further designed the preliminary diesel-electric propulsion system. Four MTU 16V 4000 diesels combine with Rolls-Royce Azipulls. These azimuthing pulling propellers offer low drag, good maneuverability, low vibration, and other efficiency benefits.

The end result of all of this is a megayacht meant for global explorations. The Rosetti 85M expedition should see a 5,500-nautical-mile range at 15 knots. Top speed should be 20 knots. Again, figures are preliminary. However, Rosetti Superyachts is confident they’ll be close.

The team evaluated many Rosetti Marino commercial craft before drawing the first line. Those lines come from Tomasso Spadolini of Design Studio Spadolini. Because the Rosetti project embraces commercial DNA, he considers her “the most ‘authentic’ yacht I’ve designed in my 40-year career.” 

With a waterline length of 277 feet (84.5 meters), the Rosetti 85M expedition has an extraordinary volume of 2,200 gross tons. Her vast open areas accommodate a certified helipad, situated either aft (above) or amidships (below). Should you prefer, the heli can stow below deck. Either way, significant-size tenders and PWCs can stay on the main deck. A sailing yacht is a tender option, too, though only with the aft helipad. (The aft location prevents the mast from interfering with the helicopter blades.)

Since the concept is for a custom yacht, Rosetti Superyachts will work with a buyer to tailor the spaces within the five decks. Design Studio Spadolini suggests a saloon beneath the above-mentioned helipad, if it’s not a heli hangar. Yet another saloon sits aft on an upper deck, the same level as a pool. The owners get an entire deck that includes private dining, plus use of much of the pool’s deck. In fact, the area between the upper saloon and the pool is for them. Here, Design Studio Spadolini put an owners’ lounge and study, with access out to the pool area. All guests can indulge in the massage area and sauna just aft of the beach club. Fold-down platforms to port and starboard make the beach club, with a gym, more inviting.

Twelve people in the owners’ party and 12 crewmembers make for a good guest-to-crew ratio. Crew accommodations and the galley are below decks, with a few extra crew berths on the main deck. Guests get staterooms on the main deck as well, while the captain is just aft of the wheelhouse. The 47’6” (14.5-meter) beam will benefit guests and crew alike. This was vital to both Dodich and Spadolini. It makes for comfortable relaxation areas and good operational access for crew.

Speaking of operations, for ease, the laundry, abundant dry and cold stowage, a garbage room, and the workshop-equipped engine room are all beneath the crew cabins. Further for ease, this time maintenance, the Rosetti 85M expedition yacht can feature a commercial paint job. Faired and finished surfaces are, of course, available, too.
