Steering ski for snow vehicle

A ski for a snow vehicle comprising a snow contacting portion and a ski mounting bracket opposite the snow contacting portion, the snow contacting portion comprising a generally horizontal surface, a keel depending from the generally horizontal surface, the keel comprising a keel base that contacts the snow surface and a first inclined surface, the first inclined surface forming an angle with the keel base of about ninety degrees or less, a transverse cross-section of the ski including a first inflection point adjacent to the keel base, a second inflection point between the first inclined surface and a second inclined surface, and a third inflection point located between the second inclined surface and the generally horizontal surface, wherein the second inclined surface is located between a first straight line extending between the first and third inflection points and a vertical central longitudinal plane of the ski, and wherein the third inflection point is between the vertical central longitudinal plane and a second straight line extending between the second inflection point and an outer edge of the ski.

A ski for a snow vehicle comprising a snow contacting portion and a ski mounting bracket opposite the snow contacting portion, the snow contacting portion comprising a generally horizontal surface and a keel depending from the generally horizontal surface, the keel comprising a keel base that contacts the snow surface, a first inclined surface, and a second inclined surface, the keel base extending laterally from a longitudinal cent-al plane of the ski to a lateral extent, the first inclined surface extending between a first inflection point adjacent to the keel base and a second inflection point intersected by a longitudinally extending inflection line, the second inclined surface extending between the inflection line and a third inflection point adjacent to the generally horizontal surface, wherein the inflection line is located no farther laterally from the longitudinal central plane than is the lateral extent of the keel base, wherein the second inclined surface is between a vertical central longitudinal plane of the ski and a first straight line extending between the first inflection point and the third inflection point, and wherein the third inflection point is between the vertical central longitudinal plane and a second straight line extending between the second inflection point and an outer edge of the ski.
