Abstract: A rack for holding water sports equipment includes a substantially upright surface, an arm, a pedal, and a linkage between the pedal and the arm. The arm is configured to hold a piece of water sports equipment between the arm and the substantially upright surface. The arm is movable away from the substantially upright surface, against a force biasing the arm toward the substantially upright surface, to allow the piece of water sports equipment to be inserted or removed from between the arm and the substantially upright surface. The pedal is positioned and configured to be moved from a closed position to an open position by a force applied by a human foot and to return to the closed position when that force is removed. The pedal is directly or indirectly connected to the arm in order to move the arm away from the substantially upright surface when the pedal is moved from the closed position to the open position.
