Being a particular hybrid yacht, which exploits the energy produced by a retractable photovoltaic park, the construction foresees that inside the hull, under the deck (main deck), and on the roof of the flybridge are installed, in special shafts , retractable solar panels that can exit and re-enter the hull itself (patented system) and that, in the roof above the cockpit and above the flybridge, additional solar panels are installed for a total of 110 m2. which produce the energy to be stored in the batteries, thus making it possible to sail even with electric motors alone at a speed of 6-8 knots for many consecutive hours, without polluting, in almost absolute silence, at zero cost (!), and with the possibility of being able to enter marine protected areas, where electric navigation is possible,usually allowed.
