Going it alone? If you need help getting your boat on your car rack, the Boat Loader can lend an arm. Prop one end of your boat up on the extension and then lift the other end onto the rack. The Yakima Boat Loader retracts into the Yakima round cross bar when not in use. Extends 28" from end of crossbar to support even the largest canoes and kayaks. Helpful in getting heavy loads onto taller rooftops. Solid steel bar has an aluminum over-sleeve for corrosion resistance and boat finish protection. Retracts out of the way when not in use. Includes 3/16" hex wrench, for installation. Fits Yakima round bars exclusively.
