  • Snowmobile skis having elongated wing members
    Patent number: 8915503
    Abstract: Snowmobile skis include at least one elongated wing member projecting laterally outward and upward from a lateral side of a base portion of the ski. The at least one elongated wing member has a lower surface that extends vertically over and laterally outward from a lower running surface of the ski. At least a longitudinal section of the lower surface of the at least one elongated wing member may include a portion having a curved, concave shape. The lower surface of the at least one elongated wing member may extend a greater distance vertically over the lower running surface of the ski near a longitudinal midportion of the ski relative to a distance by which the lower surface of the at least one elongated wing member extends vertically over the lower running surface of the ski near a longitudinal front portion of the ski and near a longitudinal rear portion of the ski.

  • Methods of manufacturing snowmobile skis
    Patent number: 7841089
    Abstract: A snowmobile ski with a pair of outboard keels and laterally projecting, upwardly slanting, lateral wings attached proximate the outboard keels is disclosed. A ski of this structure has improved flotation and resistance to side slippage in turns.

  • SWAY BAR FOR SNOWMOBILES
    Publication number: 20080246237
    Abstract: This invention relates to an improved snowmobile ski having a vertical fin on the topside of the ski with a surface area large enough to minimize or prevent sideways slippage of the ski during a turn. The fin, if a single fin is used, is located adjacent the outboard edge of the ski. A snowmobile ski with dual topside fins having outwardly projecting lips along the upper edges of said fins has improved performance in deep snow.
