looks pretty much like mine on a 83 43' ocean alexander.
The hull sides are cored with full 1/2" plywood, then strips of 1/2" plywood to act as furring strips and a base to nail the 1/4" plywood substrate to (nailed with ring shank nails), and a final 1/8" teak veneered layer of plywood glued to the 1/4" substrate with contact cement.
I am in the middle of replacing all the windows with new laminates because the old ones had bubbling of the tint around the edges of the glass. So far it has cost $160 a window regardless of the size. I have 17 windows plus 3 thick windshield panes. The cost driver is the solar tint I am using, so says the glass shop. Although the flex track and felt edge pieces arent cheap either. *sigh*
Gorrilla super glue gel has worked exceptionally well for gluing the frames and trim back together when broken. you only have to hold it for 10 seconds thankfully. Another great glue for teak is has been loctites 5 minute clear epoxy (home depot).
I plan to bed with this stuff...
here's a pic of the plywood lay up...
