It is your privacy shade for the windows. Allows light to come in but from outside your boat offers privacy. I also did a double take on what they were when coming across them. Should be a felt sack attached to the wall in your hanging locker where they are best stored.

Can I get those port hole shades from tiara or port manufacturer, or is that custom made?
