Being in a covered slip rain is typically not a problem for getting on the boat, that is until storms from the south come in. Then the back is drenched. This is my first attempt at building a canvas cover for the back of the boat. I am interested to see how it does when the winds kick up. Meter says 12 mph right now and it is doing fine. Used strips of velcro to secure it to the frames and a cheap painters cloth for in case I totally screw something up 🙂
