For the look we would say: Italian design and yes, we would be right, it is an Italian one (Paolo Bua) but it is not only the look that is interesting, the building and the performances too.
The boat is made in France on a traditional small shipyard using mahogany / glass / epoxy strip planking all that to make a light boat that weights 1550 kg being almost half of it on a long hydraulic swing keel (1.95m). A carbon rig and lots of sail make this a very fun boat, a beautiful day sailor full of character that would be also good racing.
The boat was been making quite a steer in France being tested by sail magazines with testers loving the boat. Well, I love it too
