I take the straps that come with the cover off and replace with rubber straps with the hooks on both ends. I drilled a hole in the trailer frame and put an I-bolt in it and then mounted the strap to the cover and then just hook it on the I-bolt. It keeps the cover tight all the time. This works great when trailering the boat. It allows for give while traveling and when you stop it tightens back up again. EB
