The typical silt skimmer features a broad hull and ouversized wheels. It rides 10 feet above the ground and is powered by two large sails. The vehicle can also be driven slowly, using muscle-powered capstans to rotate its wheels. A silt skimmer is most efficient in flat, open terrain, but it can also make its way through silt or dust sinks up to 15 feet deep. These vessels cannot cross the deep Sea of Silt.
