To make the cabin private at night I added a removable cover to the inside of the screen door itself. Made a piece of black Sunbrella canvas (any material you can't see through would work as well) cut to fit the inside of the vertical portion of the screen door (it's approx 18" wide x 24" high), w/2 pockets for wood dowels (1/4") to fit into (top & bottom).. Made 1/4" holes on the inside top & bottom on the vertical frames of the screen door that the wood dowels can go into holding the Sunbrella canvas making a shade... Been that way for 10+ years and works great, screen still functional letting air into the boat (top portion of screen) without making any permanent change or damage to the boat itself. May sound complicated and can take picture to make it easier to understand if needed. Let me know if you want a photo.. M2C.. BTW you can leave the cover on the door and it will still slide since it doesn't interfere at all.
