Surface traversing apparatus with stepped running surface

摘要

The surface traversing apparatus includes a main body (10) having a shovel (12) that curves upwardly at the front thereof. A rider is releasably secured to the top surface (14) of the apparatus by a binding that holds the rider's boots. The apparatus further includes a diffuser (16) which defines a stepped running surface, positioned on the bottom rear portion of the apparatus. The diffuser operates to reduce both parasitic drag and form drag while providing increased directional stability when the apparatus runs flat against the snow.
