Cantieri Posillipo Rizzardi

Cantieri Posillipo Rizzardi, Technema 80

The Technema 80 is a perfect ensemble of elegance and rationality, ergonomic and styling, performance and maneuverability and, above all, benefit from the wide building experience of the Posillipo yard mixed with the innovative character typical of the Rizzardi yard. These two builders, both with a remarkable international reputation, are now one strong manufacturing reality taking advantages from famous designers such as Tommaso Spadolini and Zuccon International Project whose innovation and technologies, know how and experience are behind the Technema's success.

This yacht has shown that all owner's requests (such as habitability and comforts demands) can be converted into reality to achieve a fully customized yacht. The Technema 80 is an outstanding yacht: this prestigious result is only possible, in my opinion, when experienced designers join leading shipyards and this is exactly the case. Building technology is perfect throughout the yacht, while the lay-out ensure a sophisticated habitability. Performances are surprising as well, and this impressive yacht 24 meters LOA with a full load displacement of 69 tons achieves a top speed of 35 knots: I believe this is only possible when both project and building capabilities are without compromises.
