I had an old style sun screen in each cabin. They were ok, but all they were was a blind you pulled and hooked around two tabs. Replacing these will not add to the safety of the boat or anything, but it sure made the cabin look nicer.
I installed Oceanair skyscreen which provide a ring around the hatch and the sunscreen slides from one end. The best part is the other side has a bug screen, which is not something I have need very often but would have been nice the few times I needed them.
Installing the skyscreens could not have been easier. The box came with four plastic parts that snap into place forming a square ring. Inside this you press a rubber gasket into a slotand they are ready to hang. I had Melek outside and she reached through the hatch and held the skyscreen in place while I screwed the four corners down.
It is that simple and the rooms look that much more clean and elegant.
