Abstract: A steering attachment for a wheelchair includes an arm assembly configured to engage a wheelchair fork comprising two outer bars connected to a shorter center member, thereby defining a gap on one end of the arm assembly to engage the fork. Attachment apertures extend through the outer bars and center member configured to receive attachment members to adjustably assemble the arm assembly to accommodate a particular fork blade. A link pivotally is connected to an opposite end of the bar assembly, and is hinged to move between an extended position and a folded position. A foot support is pivotally connected to an upper wall of the link and configured to pivot about an axis perpendicular to the pivot axis of the link. The steering attachment is connectable to a wheelchair with a single pull pin.

Abstract: A boat hull shield is disclosed including a hull perimeter bracket adapted to attach to a boat hull, the bracket extending along a port and a starboard chine of the boat hull. The hull shield further includes a convex panel, with a low-friction hard surface, for covering a bottom surface of the boat hull, having an outer edge retained by the bracket, extending from the port chine to the starboard chine of the boat hull, the convex panel forming a hollow space between the convex panel and the boat hull. A trim component is included in the hull shield which is attached to the aft end of the boat for adjusting an angle of a surface of the convex panel. The hull shield also includes a suspension component for absorbing impact force on the low-friction hard surface of the convex panel.
