Abstract
Abstract A surfboard control device comprising a foot stirrup that is secured to the upper surface of a surfboard along its longitudinal axis, which stirrup holds the foot of the surfer to the surfboard during surfing and aids in turning the surfboard by allowing the surfer to exert upward force on the board through cooperation with the surfer''s other foot, and aids both experienced surfers and beginning surfers in accurately positioning their feet on the surfboard, which position is established by trial and error and identified on a scale.
