Meet the StrongArm Kayak Loader: a system that allows a single person to load canoes or kayaks onto the roof of your vehicle. It is made from a powder-coated aluminum with a steel base. The StrongArm lets you load and unload your kayak easily but can also be removed in seconds.
The StrongArm is suitable for kayaks up to 20 feet and large kayaks up to 145lbs. More information is available here.
