We did not like the curtains on the windows and hatches in the salon. We looked into buying the Oceanair roller shades for the two forward hatches. The cost would have been close to $500. After looking around for a different way to install shades we decide to build frames and install blinds that we found at Home Depot. Total cost was under $500 for all eight blind enclosures. The frames are built out of PVC lumber. As we all know no surface on a boat is flat so some of the frames had to be gently bent slightly to install. This did not effect the smooth operation of the blinds.
