Tinted windows

The boat gets very warm in the summer,even though we have exterior net covers and canvas covers. We decided to get them tinted aswell. I found that 3m did a clear film that cuts out  up to 50% of the heat, so we put that on the front windows so we could still see out clearly. We put a darker tint on the side which blocks up to 60% of the heat, and gives a bit more privacy.We would like to have tinted the galley windows, but they are acrylic so were not suitable for th film, we were told they would bubble very quickly. We are very pleased with how much cooler th boat is in the middle of the day now.
