The origional Curtains in this boat looked like someone sacrificed the back of their blue jeans, and screwed them to the headliner. They swung to & fro even while at the dock, and did not keep the incesant Florida heat out of the cabin. I leave the Air on all the time while at the dock, and it seemed to run too much. The issue with the previous owner and myself, was that the verticle liner between the Port lights was thin, and an effort to install hangers for the top & bottom rail of curtains would either not hold or eventually damage the liner. Finally a solid solution......! I shaped the wood (Sapele), to the contours of the boat cabin, cut a 1" Channel up the center, and routed a decorative edege on the 6 pieces. I installed 1" alum angle stock into each hanger and secured with stainless bolts. The exposed leg of the alum slid behind the interior Port light trim and tightened back down solid. I wanted heavy brass rod for the curtain rods until I searched and found the only comparable material was Stair tread carpet rods. "Way to expensive"! Off to Ace Hardware,,,, Fiberglass tomato steaks were really strong and only $4.00 each. I could get them all from 4 pcs. Next I found plumbing fittings that snugly fit over the ends. On the visable ends I screwed the fittings from the interior to the Sapele,, (All hidden), and on the other end I screwed from the outside with stainless into the fitting with the excess screw going inside the rod.
