I have had Wynne Windows on both my boats, and I love them. BUT, and a big but, the opening front windows on both were useless. Had to take both out and replace with fixed glass. They hardly even slowed the water down. Now, I do fish in a lot of weather, and my current boat is very wet, so that didn't help. A few guys here praise the Bomans, and they have nice dog latches from what I can see in the pictures. I would highly suggest not bothering with the Wynne openers, unless you are a fair weather/sheltered water type.
