Any advice to prevent side slip of kayak transported laying flat on factory roof rack with “flat” crossbars, in particular something like a load stopper or “short” vertical bar? Fold down stackers wont work since one day I forgot to fold down my Yakima Big Stack and heard the big whack as it hit my garage.
In more detail, I used 1" cam strap with Yakima big stack (a vertical bar) with no issue. Vertical bar on new SUV is now too hi for garage so I use strap alone and kayak has not flown of car yet. However, when driving 75mph in crosswinds (or passing trucks) I notice some “slight” shifting/wobble of kayak and dont feel confident without something to prevent that slight side movement. I have safety ropes front +back but they dont help. Using a 3rd strap that goes from front bar to rear bar worked but looking for something that save the 2 minutes the 3rd requires every time. Brainstorming ideas but figure ask the experts here instead what might work best like…1.5" vs 1" straps, ratchet buckle instead of cam, foam on top of crossbars for more friction, tie something like rope on on 1 side to act as stopper (not both sides since I slide kayak across bar to load/unload) …or my preference is buy/make some vertical bar less than 12" tall. I saw Yakima and Thule make “load stoppers” but unclear if they adapt to factory bar or how well they actually work? Seems like only buyable ones are either really short load stoppers or too tall vertical bars.
P.S. Its pedal drive so has hole in middle plus scupper holes so could somehow tie those holes off but dont want to risk pressure damage to those holes
