I dont remember the name of the cover, thinking Sterns. I paid about $50 for it at Farm & Fleet. Menard's also sells them. They sell covers in various sizes based on boat style, and boat size. Bass Pro Shop lists them in thier fishing catalog too. So do a few of the boating catalogs. I think mine is a size A, or AA. Had it about 2 years now. Boast sits outside most of the year under my Oak tree.
The cover is heavy enough I use it while towing the boat to and from teh lake too.
It has a bow strap that attaches to my winch post. 3 body straps, and 2 transom straps. The 3 body straps run under the boat and attach to the cover on the other side. The 2 transom straps attach to the trailer.
