Summer season opening Festival of water sports in St. Petersburg. The Fort Cup is held annually under the auspices of the IWWF (3 stars rating) in two disciplines: air tricks on open water and runs in a two-level jib park. Winners are determined by the results of the overall standings, which motivates participants to comprehensive trainings. An additional motivation is a solid prize fund of the competition: $ 4,000 in 2018. The names of the winners are perpetuated on symbolic Cups, which always stay in the park #Kingwinch at Fort Constantine. Competitions attend riders from the cities of Russia and neighboring countries.
