If you look close to the bottom of the windscreen you will see the rubber stripping. This has a U shape that slides over the bottom edge of the windscreen. Underneath that is a 5/8" round hollow rubber tube. This comes attached to the U shaped trim. The hollow tube compresses and seals against the top of the boat.
I have the musroom pop up cleats at the end of the screen. That is one reason I didn't go around and down. The biggest reason it would be a pain in the ass
The other reason was it would have made the windscreen more obvious. From a good distance the black rails somewhat disappear into the black of the boat. The clear plexiglass disappears pretty easy.
Bottom line I hate it, but I am so glad I have it.
I wouldn't be without it. It does so much for you, you are willing to give up the cool lines the boat had without it. You can carry a conversation with other riders, hear the stereo, and enjoy the boat so much better.
What they should have done is drop the seats about 4 to 6 inches. That would still have left enough room to still have the seats drop down. They just wouldn't have dropped totally vertically but they would have dropped enough to be out of the way.

Roy I will PM you what you will need to make this happen if you want. Don't reach for your wallet
