ATLANTIS 50

Atlantis 50

An extremely rational interior décor contributes to the strong emotional impact that marks her outlook.

Atlantis 50 The Atlantis 50 was successfully presented at the latest Cannes Boatshow. She is the most recent yacht born from the collaboration between Architect Carlo Galeazzi and the outstanding Design and Product Development office of the Piacenza-based shipyard. Already at first glance, one easily understands how the hull is the result of scrupulous design research that - one discovers immediately - takes advantage, in a practical way, of some important technologies. First of all, the one used for the silencing and good functioning of the elegant hard top and side windows sliding system - a special feature of the superstructure of a low and rakish hull with a pleasant offshore line. Actually, much of the design philosophy of this model revolves around this area that can hardly be defined as decidedly internal or external, since it may be easily adapted to the needs of the moment.

Atlantis 50 The cockpit layout in itself, with a central U-shaped dining area and a fully-fitted galley, suggests a greater use than is the norm on boats of the same size. The same thing may be said of interiors, where a guessed choice of mixed colors serves as background to an extremely rational décor, with an almost minimalist style, offering a general strong emotional impact.

Atlantis 50 Everything revolves around the salon with its elegant galley where the six passengers may live the most "convivial" moments on board. Instead, private comfort is offered by the three cabins with capacious storing space. If the Owner's stateroom is duly privileged, the port cabin amidships does not pale at all: with its size and the double bed, it may be considered a VIP cabin. The other guest cabin, slightly smaller, is ideal for two youngsters. At sea, comfort is guaranteed by the smooth lines of the hull that with its 16°deadrise aft offers a smooth ride through the waves and at the end of the turn slightly rolls thus facilitating passengers' balance.
