The spoiler will contact the boards very early when opening the hatch. An aftermarket crossbar system, Yakima, Whispbar, Thule will give you a 1-2" extra height and allow you to open the hatch further but no much. My spoiler has a bunch of scratches on it from hitting kayaks and boards. I can open it enough to grab a few items but I usually strap the board on after I put all the gear in back.
