RAFFAELLI - MAESTRALE 52

The new Maestrale 52 , built by the Italy based Raffaelli yard, is a modern motor-yacht which investigate the yacht design of the future. Based on a project from Nuvolari-Lenard, it sets new standards on flying-bridge cruisers concepts. The Maestrale 52, in fact, explore new ideas: the round and sleek lines and the spacious flying-bridge which offer superior habitability, are just two examples. The yacht is able to give new emotions to boaters with well conceived spaces both outside and inside.

Performance and seakeepness are excellent. The hull reaches remarkable speeds, with a stable and safe ride, particularly comfortable on wave impact. Rationality and ergomomics are the two main characteristic of the external areas, where several innovative solutions ensure pleasant times on board. The wet-bar on the flying-bridge, the mooring area in the cockpit, the beautiful fore deck with the sunbathing area and the excellent and innovative design of the superstructure's windows, highlight the product's quality.

Below deck, the Maestrale 52 follows the same criteria, offering comfort and privacy. The three cabins are spacious with excellent fittings, the two bathrooms are extremely roomy and completely fitted, while the galley area offer plenty of space. The V-drive engines' installation allow a complete and rational use of the space available on board. The crew cabin, placed amidships, is comfortable and feature a convenient access to the galley. The round superstructure design influence, on the other hand, the saloon's overall beam, which result, in our opinion, slightly under dimensioned. Its well conceived lay-out, however, ensure two dinettes and a comfortable, fully equipped steering station. Finishing, as usual for the yard, is very accurate without disregarding even the smallest detail. The result is an excellent joiner work throughout the boat: the furniture, the doors and the upholstery are manufactured to the highest quality level.

The Maestrale 52 offer an incredible standard equipment list as well, which will satisfy the expert yachtsman who knows that his yacht must be a beautiful object ensuring comfortable and reliable navigation as well. The excellent market success of the boat proves that the philosophy and the constant research of new solutions which are the foundations of this project are necessary elements for building successful products.
