Abstract: A loader for loading a kayak or other article onto a roofrack carrier. Typically two carriers are mounted on a roofrack and loader is used for each carrier. Each loader has a loading cradle that is slidably mounted in a slide rail and an attachment plate for attaching the slide rail to a carrier. A kayak is supported in the two loading cradles. Each cradle is pushed up the slide rail to lift the kayak near to the carrier. The lifting can be done by a single person in steps. A locking mechanism holds the loading cradle in position on the slide rail and prevents it from sliding backward. The user may move from one loader to the other to sequentially push the loading cradles up the two slide rails, thereby bringing the kayak close to the carriers mounted on the roofrack and in position for loading into the carriers.
