Abstract: A rotatable binding for a snowboard comprises a base plate on the snowboard and a binding plate rotatably mounted on top of the base plate and including a foot binding and a locking assembly for selectively locking, at a desired angle of rotation, the binding plate to the base plate. In a preferred embodiment, the top of the base plate includes an indexing platform including a multiplicity of bores arranged in a circular arc about a central axis and the bottom of the base plate includes a pedestal, having a width about the width of a human foot, traversing the snowboard and supporting the indexing platform above top surface of the snowboard. The locking assembly includes a pin selectively moveable from a raised position, not restricting rotation of the binding plate relative to the base plate to a lowered position engaging an indexing bore such that the binding plate may not rotate relative to the base plate.
