ABSTRACT:
This is a user supported portable sail used to provide wind powered momentum for an individual on a moveable base. The invention involves the use of a balanced aerodynamic sail with the airfoil planes constructed in a way that allows the device to be used in more than one attitude. The invention also includes the use of clear panels for visibility, and the use of collapsable sections to render the device to a small portable and storable size. The support structure is provided with the means to allow it to be braced or stepped against a base and the shape itself is made to be infinitely and finely variable by the use of adjustable lines attached to the material and to the frame.
