We purchased a peek a booo blind to try in the head. The blind was easy to install and seems to be well constructed; it blends very nicely with the boat. The only problem we have is even with it open is that it still blocks out some light. We are pleased with the privacy it offers to the head but decided not to install them through out the boat because of the lost of light. I would suggest purchasing one and give it a try before buying them for the entire boat. I also think they would work great on the hatches.ToddIrish Folly C36
