Born in Turin on May 16th, 1966, he starts to familiarize with water from the very beginning in Alassio where, thanks to his father's passion for the sea, he starts sailing first on the typical inflatable boat and then on bigger and bigger boats during the classical summer cruises.
At 25 he develops his passion for regattas, which brings him to enroll "wherever there's a space" up to becoming a member of the crew of Loro Piana's My Song maxy. After two years at high level he decides with his brother Edoardo to pass on the other side of the barricade, becoming ship-owner with a Platu 25 (Fra Martina) that soon becomes the reference point for the class thanks to its constant successes. In the palmares he counts an European Championship and a second placement, an Italian Championship, a second and a fourth placement at the World Championships.
In 2007 the new challenge of the Meleges 24 starts. Since professional yachting is still a hobby, Vanni, after classical and law studies becomes an entrepreneur, on one side in the industrial plants for field of metal sheets processing, on the other as producer and sommeiller of wine, obtained from the family's vineyards.
