A snow sled comprising a seating portion that includes a lightweight space frame having a suspension-type seat stretched among the space frame. The sled further includes a steering portion and articulated steering mechanism that links the steering portion to the seating portion. The articulated steering mechanism allows the steering portion to be pivoted laterally relative to the seating portion so as to make the sled readily steerable. A pair of rear skis are removably attachable to the seating portion. The steering portion includes a ski support and a pair of front skis pivotably attached to the ski support. Chatter and movement of the front skis are dampened by a pair of boots that engage the ski support and the respective front skis.

What is claimed is: 1. A snow sled for use by a person on snow, comprising: a longitudinal central axis; first and second longitudinal sides spaced from said longitudinal central axis on opposite sides of said longitudinal central axis; a body that includes: a seating portion having an upper surface and a lower surface spaced from said upper surface, said upper surface for receiving a person in either a seated or lying position during use; a pair of spaced-apart snow-engaging members for supporting said body on snow during use, said pair of spaced apart snow-engaging members supporting said seating portion on corresponding respective ones of said first and second longitudinal sides so that said lower surface of said seating portion is spaced from said snow; and a leading end; and a steering portion comprising: a ski support pivotably secured to said body at said leading end proximate said longitudinal central axis so that the snow sled is steerable by pivoting said ski support side to side during use, said ski support including first end and second ends spaced from one another on opposite sides of said longitudinal central axis; and first and second skis attached to said ski support at corresponding respective ones of said first and second ends; wherein: said ski support includes a curved central tubular portion supporting said first and second skis; and said steering portion further comprises a linkage linking said ski support to said seating portion, said linkage being substantially flexible horizontally and substantially rigid vertically when said pair of spaced-apart snow engaging members and said first and second skis are resting on a horizontal surface; said linkage including a substantially flat bar having a longitudinal axis extending between said body and said curved central tubular portion, said substantially flat bar having a thickness selected to make said linkage substantially flexible horizontally and a width selected to make said linkage substantially rigid vertically. 2. A snow sled according to claim 1, wherein said pair of spaced-apart snow-engaging members are skis. 3. A snow sled according to claim 1, wherein said pair of spaced-apart snow-engaging members are runners. 4. A snow sled according to claim 1, wherein said ski support includes hand/foot grips. 5. A snow sled according to claim 1, wherein said body comprises substantially tubular members and said upper surface of said seating portion is defined by a membrane supported by said substantially tubular members. 6. A snow sled according to claim 1, further comprising: a first boot engaging said first ski and said first ski support; and a second boot engaging said second ski and said second support; wherein each of said first and second boots are designed to dampen chatter of corresponding respective ones of said first and second skis during use of the snow sled.
