I took both of my kayaks to last year's Newfound Rendezvous, a 13 hour trip, mostly at 65-70mph and on the heels of hurricane Floyd. I hit some really vicious winds, but the internal bungies worked great keeping the covers in place. I do have an internal tether (a length of lightweight nylon rope) that anchors the cover just in case which I recommend. It's never had a chance to save the cover, but I drive easier knowing it's there.
