Nice as I think it ref. deck leaks and structural integrity?
Any other vessels out there built with solid glass decks?
Rare, but my boats decks built in 1961, are solid glass. The decks were molded in one piece, through bolted to the hull flange, and glassed over.
Instead of core, Alden spec'd a support framework below of small framing members. These were fastened to the wood cabin and to fiberglass 'ribs' at the outboard end, then glassed to the approximately 3/8" thick glass decks, above.
What an operation! Not only was that procedure time consuming, Alden later specified bolting 'sisters'(raw wood in photo) to the frame members, for added stiffness.
The bottom line they learned was, it was difficult to make a solid deck stiff. They quickly went to cored decks after these 52 Alden Challengers were built.
53 years down the road, it wasn't such a bad idea. The fiberglass hull and deck on my boat so far, are like new. I've never had an issue with any core rot. Because they're solid, backing plates and bedding have no compression problems and deck leaks are very, very rare.
The original diamond pattern non-skid is worn but I painted it a few years ago, and it looks great.
