Just a suggestion if going with the quick tarp cover method. Yes use a good tarp. I use a Harbor Freight HEAVY duty tarp on the small boat and put it over a tall PVC pipe “A type” framing going the entire length of the boat to keep any rain or snow from pooling and sagging it. Then I can pull the tarp, lift the framing and the nylon cover is dry and ready to tow in no time at all. There are a lot of frame ideas online. Either way, you should get a good cover to keep things dry. Best of luck.
