Hey Nebb ... We used heavy-duty pallet-wrapping material with a layer of cardboard wedged in. It finally started to loosen a little about 60 miles from Soldotna and I had to re-tape a few places where the beating of rocks actually tore through a whole layer of it and left some flapping. It never left the boat uncovered though and you would never be able to tell if it was barged here or driven

Save a few for me for when we get home !!
