Sergio Sorrentino competed in Dragon Class sailing at the 1956 and 1964 Olympic Games. He was Dragon World Champion in 1958 in Sweden, and won European Dragon titles in 1953, 1956, and 1964. In 1956, while training for the Olympics at the Panzano Duke, Sorrentino noticed that the southwestern side of the basin was an ideal spot for a marina. He worked with his friend Annibale Pelaschier to create the marina which they named the Hannibal Marina. At the Hannibal Marina, Sorrentino started the Tito Nordio School, the first sailing school in Italy. By the 21st century the Hannibal Marina had over 320 yacht berths, some suitable for boats up to 160 tons.
