WB you are right about it being under a leanto when I deployed it today. The bow of the boat sticks out of the east end of the cover, but the view of the western sky is blocked by the cover. I didn't think of that. It was stowed and deployed several times yesterday; with the result being the same.
I'm going to Sardis in the morning. I'm going to hold off on ordering the part until I see what happens.
