Saw these on a friends Allmand 31 and can't for the life of me remember
the name. These covering replaced conventional blinds/drapes. The
product consisted of two thin layers of plastic custom cut for size, that
mounted on the interior surface of your cabin windows/ports. Their design
allowed the one layer to be slid a certain amount sideways over the other.
Each layer of plastic had alternating bands etched to opacity in their
surfaces. Depending on alignment the bands would either admit or not admit
vision into/out of the cabin. Anyone seen these and/or remember the name?
Cheers
