Sliding hatch fix

[Salvonight]

Good morning,

I recently purchased a boat and don't know much about boat repair but consider myself handy enough to try to do as much diy as I can. The teak sliding hatch has seen better days and I was hoping to repair it this summer. I believe the struts are good but the tongue and groove teak inlays have started to rot out. I was thinking about a marine grade plywood which I would then fiberglass over. Thoughts?

No need for the fiberglass. Maintaining a good coating of a quality varnish should suffice.

You do need to use a high quality plywood with multiple plies or the panels will wrap.

An image of your project would be helpful in understanding the design.
