though many of the champions come from states such as săo paulo, goiás and rio grande do sul, carioca competitors such as alessandro conceiçăo da silva and antonio araujo farias, are making big waves in the scene, particularly in freestyle events. the jet ski was invented in the late 1960s by clayton jacobsen ii, who quit his job as a banker to pursue his vision of a motorcycle for the water (he was a motocross aficionado who wanted something softer to land on) - the original models required that the user remain standing, and thus were somewhat difficult to handle in rough waters. the vehicles did not attain widespread popularity until the 1980s, when the introduction of two-person and sit-down designs made the jet ski viable to a much wider market, in addition to continuing advances in stability and safety.
