There is disclosed a new teaching aid and support device for use with a windsurfer rig, which rig usually includes a mast, a boom, a sail, and a universal joint. The teaching aid and support device comprises a stationary base member for supporting the windsurfer rig. The stationary base member is in the form of a shallow, inverted receptacle having a top planar surface and depending side walls which are arranged and constructed so that when the bottom edges of the sidewalls of the base member are placed on the ground the base member is securely and non-rotatably supported from the ground. The top planar surface of the base member has a suitable mast receiver opening whose vertical center line is near the geometrical center of the base member. The device also includes an arrangement for securing the mast to the base member.
