Check with a local kitchen cabinet maker. My local guy had laminate samples that matched perfectly. He placed an order for me and it arrived about a week later.
I was told by the cabinet maker to use a powder glue mixed with water. He said it had better heat resistance if your boat is exposed to the sun. I found the adhesive at ACE hardware.
The laminate comes in a 4' X 8' sheet. I paid around $70.00 for the laminate sheet. Now all you need is a 4' X 8' sheet of plywood. I used an exterior grade and painted epoxy on the edges so it would not absorb water.
I like the original look.
