My Oday 30 windows (2 on each side) are old, cracking and leaky. I would love to replace but cant seem to find replacements specifically for my boat. I am afraid to take them apart as the frames are so brittle I fear I may make matters worse. I also hate to go the route of putting new plexi/lexan over them from the outside which I have seen so many times. At the boat show, I was told that many custom companies don't have the ability to make certain radius frames. Has anyone ever replaced these windows with real Oday replacement windows or does everyone just have layers of sealant on their boat as I do?
