Soft deck ,driver seat

[SkunkBoat]

cut a rectangle out. use a circular saw with a fine blade and only go in 1/2" . try to chisel out the wood & top skin, leaving the bottom glass skin intact. sand it clean. If you can save the whole top skin, reuse it later.

Replace with exterior grade AC or BC douglas fir ply. Coat it with boaters resin ( with hardener). Let harden. In about an hour, squish it in place with some adhesive filler/resin (Bondo in a pinch).
Glass over the top and fair it using filler/resin (Bondo). sand it flush.
Coat with a thin "painted on" layer of resin( you could use epoxy here).
Paint to match as close as possible.


Now you gotta paint the whole deck....
