I don't know that there is anything that can be adjusted with the windshield itself.
The problem may be more complicated: Your "upper hull" may have been able to sag down in the middle a little bit, which would allow the consoles to lean a little towards each other. Put another way...Imagine as you step on the floor directly below the walk through window...if your weight is able to push down on that floor area, then that in turn would pull inward on the left & right consoles. This would also cause the windshield to not close or not align.
You could look from inside your ski-locker, and from under the bow seats, for how the "upper hull" is supported. On my Horizon 240 (2010), I can see from inside the Head (port), and Storage Locker (stbd), that the upper hull bow walkway is supported as follows: 1. There is wood structure surrounding the ski-locker that provides a platform for the upper hull to sit on. 2. There is a layer of carpet
over this structure, and under the fiberglass bow walkway. I presume they used the carpet to prevent rattle or chaffing from any movement between the upper hull and the lower structure, but I wished they used something that wouldn't absorb water. Fortunately, mine has always been kept very dry.My windshield is out of alignment by about 1/16" (1.5mm)... that is, I have to push apart on the two halves of the windshield to get the walk though window to close. My theory is that the carpet mentioned above has compressed. I have been considering inserting a shim or shims under that area to correct this.
