A surfboard accessory (1) includes a surfboard leash cuff band (2) and a tourniquet assembly (6-11) integrated in the cuff band. The cuff band has a body (5) and a closure device carried on the body for closing the cuff band in a loop around an ankle of a surfer. A tourniquet strap storage component (23), can be carried on the cuff band (2) and arranged to removeably store at least a portion of the tourniquet assembly. When the portion of the tourniquet assembly (6-11) is stored, the surfboard leash cuff band is closable around the ankle by the closure device and operable for surf retention without obstruction by the tourniquet assembly. When the tourniquet strap assembly portion is removed from the storage component (23), the surfboard accessory is arrangeable as a tourniquet for controlling extremity blood flow in the limb.
