Abstract: A surfing simulator which uses, in combination, a ball bearing turntable, an adjustable spring plate assembly and a flexible mounting pad to connect a riding deck to a stationary supporting base. In operation, the surfing simulator is mounted by stepping onto the riding deck near its center. As the user's feet are moved apart into the surfing stance, the user's weight can be shifted and rotational forces applied to create and sustain a complex rhythmic motion combining spin, tilt and rocking, which, when properly executed, enables the user to closely simulate and practice the movements, stances and reactions required to perform the sport of surfing.
