What a nice looking building you made. Can you give a discription of what you made it out of? Are the ribs electrical conduit tubing? It would make a terrific greenhouse using a UV type plastic roll. That use to be expensive. Maybe you could get a couple of UV protected clear pannels at the lumber yard and wire them inside above your head end to end over your boat for protection. That would run about $30, but then maybe you don't need them at all.
