Has anyone designed or found a source for a cover that extends beyond the standard Surlast cover that comes with your boat, specifically the floor areas outside the rails at the back. I have the swing-back option with the chrome rail that goes around it at the back. The standard cover goes under the rail and snaps to the engine hole area but leaves the port and starboard stern floor areas exposed to the elements. Likewise, the front floor, outside the gate, is exposed, though I'm less concerned about that area as it's fully inside my boat house. I'd be most interested in a cover extension that wraps around the swing-back rail and fastens to the outside corners at the stern. I'm also interested in a "bib" that would extend down to the gunnels on the sides to protect the colored areas on the side of the boat.
