A recreational snow sled comprises an elongated molded plastic shell having a longitudinal central rib forming a U-shaped bottom channel of gradually increasing depth toward the rear of the sled. The sled is designed to carry a person seated in a kneeling position straddling the hump formed by the central channel. The rider is restrained at the knees by a strap running across the forward gunwales of the shell. When the sled is sliding downhill, the central channel tends to form a ridge of packed snow enhancing axial stability and maneuverability. The angle of attack may be controlled by leaning backwards so that the front of the sled is tilted up by the knee strap.

A downhill snow sled, comprising an elongated shell having a shallow central longitudinal channel with a smooth rounded inverted trough-like contour throughout its length gradually smoothly continuously becoming more pronounced from the front to the rear, said channel having a smooth continuous surface facing the snow free of obstructions and abrupt changes in contour such that in unpacked snow conditions the entire channel fills with a conforming ridge of snow over substantially the entire length of the channel, said shell having a continuously curved bottom and the top of the trough-like channel being continuously curved in the same sense as the bottom of said shell, the curves defining the bottom and top of the channel, viewed from the side, being substantially nonparallel over the length of said channel and approximately intersecting toward the front of the sled defining a crescent-shaped profile for said channel, said channel being shallow and narrow enough admidships to allow a rider to straddle the hump formed by the channel in a hunkered-down position with the legs substantially completely folded beneath the rider resting on the floor of the shell on either side of said hump under the rider\s body, and leg restraint means for engaging the tops of the lower thighs of each leg of the rider in said hunkered-down position and urging the legs against the floor to secure the rider\s folded legs to the floor of the shell on either side of the hump so as to bind the rider\s legs to the sled in a fixed position, whereby said channel cuts a ridge-like track of snow providing axial stability for traversing a hill and the rider by shifting his weight can change the direction of travel and reestablish a new track to traverse back and forth down a hill.
