I don't like starboard as it tuff to glue, seal, match colors, screws bugger out easy and it loves to warp.
After cutting out the old bulkhead, save it for a pattern. The new one will have to be installed in two pieces.
I chose to use 3/4" PVC board as it is simple to seal, glue, cut, sand & paint.
1. Cut your new bulkhead using your old piece as a pattern.
2. Cut out the hatch door with a jig saw.
3. Now cut the bulkhead in half vertically down the center.
4. Trial fit the hinges, hardware, speakers what ever.
5. Install the two pieces from the inside using PVC glue too seal the two pieces together at the cut lines.
6. Sand & Paint, install the hatch & hardware, then caulk the sides.
7. Load it up with Sears Catalogs
