Yakima JayLow - The JayLow by Yakima is the "Swiss army knife" of cartop kayak racks, it can hold one kayak in its supportive J-Cradle, or convert into a kayak stacker to support two boats. The padded J-Cradles spread out the boat's weight, which is especially nice with more fragile expensive composite kayaks. The integrated ramps on the out-facing side of the cradles provide a smooth, non-scratching surface for sliding your boat up onto the cradles. If you need to carry two kayaks, simply lock the padded arm in the upright position and put the second boat on the other side. When not in use the padded arm folds flat to reduce wind resistance, and it includes straps for lashing one boat to the rack and bow/stern security straps. It fits on round, square and most factory cross bars, and locks securely with SKS Lock Cores (sold separately). Make sure you are ready to roll when the water is
