That depends on the size of the kayak and the vehicle you’re using. If you’re transporting a smaller recreational, whitewater or touring kayak, it can be transported on top of most cars that have a roof rack or even just crossbars. Racks made for kayaks are available, or you can jerry-rig padding, cam straps, or bow and stern tie-downs. Pickup truck owners can strap a kayak onto the bed of the truck. Be sure to pad the hull adequately and secure the kayak so it doesn’t slide around and scratch the hull.
