The straps are what set this pair apart from plain J hooks: the boat rests in the padded arm and the webbing closes over it, so a gust under an open garage door does not lift it out. The 13-inch depth takes wider sit-on-top hulls.
At 8.1 pounds for the pair, the hangers go up on a garage wall as easily as under a dock or on the side of a boat house. Mount them into studs with the hardware in the box.
You will work overhead or at the top of a stud wall, so set the ladder on a level floor, face it and keep a hand on it while you drive the screws. Fasten the brackets into solid framing (a joist, a rafter or a stud), never into drywall alone, and read the instructions in the box first.
