Following the announcement that Rosetti Superyachts SpA will start building large custom yachts at the San Vitale shipyard in Ravenna, Italy, the new company has released details of its 85m expedition supply vessel concept designed by Tommaso Spadolini.

“This is the most ‘authentic’ yacht I’ve designed in my 40-year career,” says the Italian designer. “A fundamental part of the design process was reviewing the many commercial ships launched by Rosetti to date. These rugged, seaworthy vessels are required to operate around the clock in all weathers, and that same DNA has been integrated into the design of the 85m expedition concept.”

“Another key consideration was that the project had to be buildable following design to market and design to service criteria,” adds Fulvio Dodich, chairman of Rosetti Superyachts. “I’ve known Tommaso for over 20 years and we worked together to develop a design that combines his creativity with my knowledge of the needs of the market, while also meeting the technical criteria required by Class for unrestricted navigation.”

The concept is available in two versions, with a fully certified helipad located amidships or aft. Both configurations are rated at approximately 2,200GT and can carry large tenders on deck, but the aft helipad offers several practical advantages. A sailing yacht, for example, can be stowed amidships without adversely affecting helicopter operations. With minimal modifications to the design, the spacious salon under the helipad can also be replaced with a dedicated helicopter hangar.

“Despite the abundance of exterior space, we arrived at a general arrangement that makes optimal use of the interior volume of the forward superstructure,” says Spadolini of the five-deck layout.

The lower deck comprises the galley, crew mess and lounge, and accommodation for 12 crew (the captain’s cabin is on the bridge deck). The main deck houses four double guest cabins with en-suite bathrooms, plus additional crew accommodation.

The full-beam owner’s deck features an open-plan suite forward, His & Hers bathrooms, a walk-in wardrobe, and aft dining room. The upper deck forward is also dedicated to the owner’s use with a private lounge, study and access to the open foredeck with pool. Another salon aft serves as a media room and/or sky lounge.

As a full-custom project, owners can bring in their own interior designers, although Spadolini has developed an interior proposal that he describes as “contemporary and comfortable but not lavish.”

The hull form has been developed by the naval architects at Rolls-Royce Marine in Norway for optimal efficiency and seaworthiness even in heavy weather. Special attention was focused on ensuring ‘dry’ cruising with a narrow entry, distinctive bow flair to reduce sea spray and a high main deck forward that is 12.5m above the waterline.

Rosetti Superyachts further chose Rolls-Royce as the supplier for an integrated solution including engineering and equipment as the engines, power electric system and propulsion units. The initial proposal is for diesel-electric propulsion using four MTU 16V 4000 series engines as diesel generators combined with Azipull by Rolls-Royce for a maximum speed of around 20kt and a cruising speed of 15kt.

The 85m is the largest in the new range of concepts proposed by Rosetti Superyachts designed by Tommaso Spadolini.
