A symmetry surfing system enables a surfboard with two ends both of which may be controllably switched between roles of front end and tail end, thus giving the surfboard dual-directional capabilities. A removable fin system may be disposed at the two ends so that when the surfer selectively activates the footplate of the removable fin system, one or more fins extend into the water. The removable fin system may be modular so as to facilitate interchangeability and installation processes. The system may preferably include a harness to be worn by the surfer. A winding reel is attached to the surfer preferably via such a harness worn by the surfer, and winds a centered leash that secures the surfer to the surfboard under tension. The symmetry surfing system maximizes surfboard maneuverability and surfboards' potential for aggressive trick surfing.
