Re: Windsheild Problem
Alright, cool.
As the other, more seasoned members have said, you have a structural situation. I know on my boat, (that needs complete restoration) I can grab the front hand rail and rock it to the point the transom is flexing like a wave.
I too have the walk through window on a bow rider. The window flexes in the space up and down when I rock it.
It has to do with the boat weakening over time. Wave chopping and wear and tear, water intrusion, rot, ect. All contribute to the demise of the boat over time. As fun as the water is on a boat, it's also it's worst enemy. Over time it just breaks it down. Just like a car on a rough road I guess.
So, what can you do? You can get in there and rip the crap out of it, or, you can shim it with some cedar shims as a temp fix. Or...anything in between those extremes. Heck, if you want, just live with it for a season and ditch the boat.
I don't know what your plan is for it, but eventually, as these fine people that are trying to help you said, it will have to be addressed if you want to keep it.
THAT, might mean a total gut and restoration. Depending on how bad it's gotten, and how well it's kept. Once water is in wood, it's downhill from there.
Judging by your picture, eventually you're going to have some bigger issues with the boat. Things have gotten, and are getting wet.
I wouldn't panic, but be aware of it, and come to that acceptance.
My best,
