The first fins were imagined and drawn by Leonardo da Vinci in the 17th century. It was organized as a sporting practice during the beginning of the 1960s. The first European Championship was organized in Italy in 1967. The fins were still made out of rubber. Very quickly the need appeared for replacing them by more sophisticated material. The Russians were the first to use glass fiber in 1970. In 1972 the mono-fin makes its appearance at the European Championships in Moscow. Within a few years, it supplanted the traditional bi-palms in the majority of competitions and opened new chronometric views for the athletes who reach speeds of more than 13km/h.
