[dropcap]T[/dropcap]he new company has released details of its 85m expedition supply vessel concept designed by Tommaso Spadolini.
The concept is available in two versions with a fully certified helipad located amidships or aft, depending on client preference. Both configurations are rated at approximately 2,200GT and can carry large tenders on deck, but the aft helipad offers several practical advantages.
The Italian designer says:
“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.”
The lower deck comprises the galley, crew mess and lounge, and accommodation for 12 crew. 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 & Her bathrooms, walkin 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.
Spadolini’s exterior styling is robust, but his signature strip glazing adds a touch of superyacht elegance to the otherwise purposeful design in line with an expedition yacht or shadow vessel. 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.” Large tenders are fundamental for expedition use and the portside garage on the lower deck has space for two tenders, plus various Personal Water Craft (the MOB tender is stowed in its own covered bay on the foredeck). To starboard there is a massage parlour, sauna, dressing room and bathroom connected by a corridor to the huge beach club aft with gym and fold-down platforms on both sides.
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 (MTU is part of the Rolls-Royce Group) as diesel generators combined with Azipull by Rolls-Royce for a maximum speed of approx 20 knots and a cruising speed of approx 15 knots. In addition to low drag and high hydrodynamic efficiency, the azimuthing pulling propellers provide excellent maneuverability, fuel efficiency, course keeping, and low noise and vibration levels.
