An adjustable, rotatable boot-binding mount (20) includes a swivel plate (40) having threaded mounting holes (24) therein to which a conventional boot binding (60) or boot may be mounted. The swivel plate (40) is rotatably retained within a base plate (30) which is securely fastened to the top surface of a snowboard (10) or other recreational board. During normal use, the swivel plate (40) is automatically and continuously locked against rotation within the base plate (30), thereby securely maintaining the boot binding in a desired angular position relative to the snowboard. At other times, e.g., while standing in lift lines or riding a lift, a quick release mechanism (27, 48) allows the swivel plate to be temporarily unlocked so that a different angular position of the swivel plate (and hence a different angular position of the boot binding or boot) relative to the snowboard may be quickly and easily realized.
