I don’t use a dust cover while transporting. I do use one in my garage to keep dust and especially
Ly sawdust off my boat. I bought several 10’ tablecloths from tableclothFactory.com for $12. I use them to make gathered-end hammocks. I had an extra and I use it to cover the Outback. I use spring clips, one under the bow and one under the stern to secure. Since mine is a 10’ cloth it exposes about 1.5’ on each end. There are longer clothes for just a few dollars more. Hope this helps.
