Blue Belle" is 40.45-m long and is distinguished by her large, brightly-lit internal volumes which, along with the luxurious decor and the attention that the designers and the shipyard have paid to the layout, make "Blue Belle" a particularly comfortable yacht.

The team that worked to make "Blue Belle" a reality has found answers for all of the questions connected to the often contradictory requirements of naval design and architecture. The result is not a compromise but rather a combination of solutions. This pleasure craft consists of three decks and a fly deck, the latter a truly remarkably large sundeck which, in the forward area, features a Jacuzzi hydro-massage tub surrounded by sofas and lounging areas. In the stern area, protected by a retractable awning, there is a cocktail cabinet with yet more sofas and a dining area for ten. The entire area is glassed- in, offering passengers a lovely view towards the stern. The upper deck includes the control station, forward, which has the latest electronic navigation-instrumentation, astern of which is a double cabin for the master and a spacious saloon with a storage area and a bathroom. Out in the open, in an area well protected by the extension of the fly, there is a dining area for 12 people. The tender is stowed aftmost, with a davit for hauling and launching. The main deck includes a large saloon with adjacent dining room for 10 guests, forward of which is the owner's suite, equipped with a king-sized bed, two separate bathrooms (each with bathtub and shower), an office with two writing desks and plenty of space. On the same deck, we find the galley and a storeroom, a service bathroom with access from the various decks and, aftmost, a large relaxation and conversation area. Two wide, side ladders lead from here to the stern deck, which is actually the transom reversed. This solution protects the overall aesthetics during sailing and, thanks to the stern's rounded shape, gives the "Blue Belle"'s profile elegance and soft lines. The lower deck consists of two roomy VIP cabins with queen-size beds and bathrooms with tubs, plus two guest cabins with large twin beds. The stern area of this deck is reserved for the crew and has independent access by means of a ladder leading from the galley to the three double cabins, with separate bathroom and mess hall. In the open, astern, there is a relaxation area beneath the deck windows and equipped with a C-shaped divan and coffee table. There is an additional seating area, abeam, foremost on the main deck, near the steering controls and a second tender equipped with a davit for hauling and launching. This area is accessed by means of two side ladders and is well protected from the quarter boards. The shipyard decided to build this luxurious yacht of aluminium, thus reducing weight while ensuring the strong, rigid structure that a boat intended for long cruises must have. The boat has a displacing bottom with bulbous prow, a detail usually found on medium- and large tonnage boats, used in this case to reduce resistance to motion and to increase stability. To reduce the swaying (rolling) that the boat is subjected to, particularly in a seaway, the shipyard equipped "Blue Belle" with trim stabilisers by Koopnautic/Vosper, which also made the powerful 75-kW prow propeller. The owners of the boat shown here are Walter and Doris Goldstein, who instructed the designers concerning the basic elements of their ideal yacht and contributed to the design and layout of "Blue Belle"'s interior. For the decor, artists as well as designers were involved, including Gianni Giannicci (for the glasswork in the saloon on the main deck), and Serge Vandercam (for the ceramic tiles in the saloon on the upper deck). Given that this is a yacht for ocean cruising, the onboard systems have been designed so that they can be monitored constantly by the crew. In particular, the monitoring system developed by San Giorgio Sein of Genoa has been adopted. As far as the communication systems are concerned, in addition to DGPS and SSB apparatuses, "Blue Belle" is equipped with a Satcom Furuno Fleet 77 system with ISDN, MPDS and Inmarsat Mini M. In addition, there are satellite aerials for receiving TV signals, wind in-struments, an echo-sounder and all of the electronics equipment required by GMDSS prescriptions.. As far as the tenders are concerned, there are two rubber dinghies (a Castoldi Jet 5.80 and a Scanner Jet 3.60, both equipped with hydra-jet propulsion). For the motorization, the shipyard decided that 2,285-HP MTU 12V TE94s were the ideal engines, thanks to which "Blue Belle" runs at a maximum speed of 21 knots, with a cruising speed of 19 knots and a range of 12 knots of 3,500 miles.
