The convenience of a stacker without having to remove it in the off season. Yakima's BowDown carries one boat on padded "J" cradles and then folds down to provide a clean silhouette. The BowDown carries one boat on its side, on top of the vehicle. When you're not using it, fold it down to keep a nice clean look to vehicle and reduce wind whistle. Padded hull guards prevent damage to your boat. Fits round, square, and most factory crossbars out of the box (fit list on carton). Locks to crossbar using SKS locking system (lock cores sold separately). The BowDown comes with heavy duty straps to secure your boat.
