On my old boat, the tie down straps when the boat was on the trailer didn't touch the sides of the hull. But on my new boat they do, and I'm starting to get some wear on the gel coat under where the straps go. Does anyone have suggestions for how to prevent that? I'm envisioning a sleeve over the webbing of the strap, similar to the soft sleeves they used to put on shoulder belts years ago (for those old enough to remember the sixties and seventies). What would be a good material for that? Has anyone found a better solution?
