Rosetti Superyachts has teamed up with Italian designer, Giovanni Ceccarelli and added two new tri-deck concepts to its range of supply vessels. 
Measuring 35-metres and 50-metres respectively, both new supply vessel concepts have been designed to make maximum use of the main deck for transporting tenders and toys.
The designer behind the new concepts, Giovanni Ceccarelli is particularly experienced in the field of sailboat design, with prior achievements including roles as chief designer of Mascalzone Latino, the 2003 America’s Cup contender, and +39 Challenge that competed in the Louis Vuitton Cup in 2007.
“The two designs for Rosetti Superyachts came about from my desire to work with a shipyard that I know very well as itis based in my own home town of Ravenna, and from my longstanding friendship with Fulvio Dodich,” explains Ceccarelli.
He continues, “In both concepts, the hulls and superstructures are part and parcel of each other, much like in sailboat design. They are not simply exercises in ‘redressing’ a standardised platform; instead, the hull lines and topsides are inextricably linked to give continuity to the whole. I wanted to create an original exterior profile distinguished by clean, essential lines that eliminate superfluous elements to arrive at a truly timeless design.”
“These new concepts join our stable of projects developed by two other designers and already presented,” says RSY partner and chairman Fulvio Dodich.“The brand mission of Rosetti Superyachts is to provide our clients with as much flexibility as possible by offering a wide range of different proposals that can be further customised according to their needs.”
Drilling down into the concepts themselves, their steel hull forms have been developed to provide low hydrodynamic resistance and are inspired by similar processes used in racing sailboat design.
With both concepts using aluminium superstructures, composite materials are used for the top deck, in order to ensure optimal weight distribution and a low centre of gravity to reduce motion and increase comfort on the move.
As for the layouts, both interior general arrangements offer an owner’s stateroom on the upper deck with 180-degree views aft through the full-height glazing, as well as a private terrace.
The 35-metre concept has a beam of 8.25-metres, with space on the main deck aft for stowing a tender with accompanying crane and a 6.7 square-metre infinity pool. 
As an alternative, when the pool is covered there is room for a mini-submarine in addition to the tender. Moving inside, you can find a spacious main salon with dining area and forward galley, direct access to which is provided from the crew quarters.
The upper deck is dedicated for the owner’s use with the master stateroom, bathroom and walk-in wardrobe located aft and providing panoramic views of the sea from the private terrace. 
Below deck, four ensuite cabins provide luxurious accommodation for eight guests. 
The 50-metre concept has a beam of nearly 10 metres.
The main deck is arranged across two levels and covers a total area of 170-square metres, including a 13-square metre infinity pool and large beach club.
The heated pool can be enjoyed as a hot tub in colder climates. In addition, this space can also be used to carry toys or a mini-submarine for underwater exploration, with the tender housed separately inside a dedicated garage. 
As with the smaller, 35-metre concept, the main deck features a large open-plan lounge and dining area separated by the staircase and integrated bar unit. The owner’s suite is located on the upper deck overlooking the aft deck. Her sun deck is equipped with a Jacuzzi, dining and relaxation area. 
Both designs offer gross tonnage below the 500GT threshold, with power provided by twin MAN main engines (1,000hp and 1,400hp each for the 35-metre and 50-metre vessels respectively), in order to achieve both comfort and efficient performance at displacement speeds.
