My locker covers delaminated and were coming loose at the piano hinges.
Eden Saw, in Port Townsend, had a nice high quality marine 4x8 plywood with a premium surface layer of sandable mahogany on both surfaces.

I stained mine with a teak color, sealed them, and adhered some auto pin strips. Then applied a quality chemical varnish. After it tacked up a pepper of silica sand made them grip in wet weather as I'm too old for doing the splits. And you will if you don't.

The secret is to only prime paint the underbelly. If you understand that in the marine environment wood encapsulated in a non-breathable varnish will dry- rot. My old hatches (by others) were totally varnished on all sides...they rotted and delaminated in just a few years.

The nice thing about these is they are one piece...no glue or pegs. The hasps are thru-bolted with brass smooth heads, and they don't leak. And not because it never rains much here in Liberty Bay. It mostly sunshines all the time and these cockpit lids can take the torture! Told you. -Bruce
