The toboggan, for at least one person in a sitting or prone position, is made in the shape of a boat. The toboggan has a rounded bow and an undersurface which is curved in both the longitudinal and transverse sections. The undersurface of the toboggan is provided with longitudinal rips (3,4,5) with a straight central rib (5) and curved ribs (3,4) on each side. These ribs enable the toboggan to be steered by the crew moving their weight to one side or the other so that the curved ribs (3,4) are pressed more deeply into the snow. USE - Toboggans.
