My recommendation goes as follows: Have a canvas shop make you a cover that is four pieces. Your cockpit, then a bow cover that is seperate, they snap together( Thats what i have,great to put the bow on for overnights) Then side skirts that zip into the bow and cockpit covers. I will get the side skirts sometime when I get as rich as Pocket Change

. I know of a 42 Baja, and a 38 Cig in my area with these and they are sweet. Have the company put zippers in so you can open your hatches while overnighting, and also half circle zippers at each of the bolsters so you can have your cockpit cover on and drive if its raining. MIdnight
