  • Patent number: 7090229
    Abstract: An anti-darting ski for snowmobiles, the ski including a longitudinally extending runner with a central keel. A generally flat wear strip with two skags is attached to the bottom of the keel. The wear strip is contoured to match the bottom surface of the keel. The skags are laterally spaced beneath the wear strip such that their inside surfaces do not extend towards each other. The skags and wear strip may be mounted flush with the outside edges of the keel. The skags may also be located asymmetrically about a longitudinal center point of the ski. The dual skag system acts to minimize darting of the snowmobile in the snow.
