I am wanting to construct a cockpit shade. I have found after only two trips out in the Texas sun, this is a necessity, otherwise, you cook! In the piles and boxes of gear I acquired when I bought my H-22 was a canvas cover with wooden poles sewn into it and an opening with the same fasteners found on a sail cover. The width of this cover is approximatly the same as the cockpit width and it has bungee type tiedowns in several locations. I have included a picture. Does anyone know what this is....does it belong to an H-22.....if so, how does it install????
