Spongy Deck Hatch

[Capt.T]

My 1991 Doral Prestancia 255 has a "spongy deck hatch" over the engine compartment. When walking on it, it flexes approx. 2-3 inches. I'm looking for a way to reinforce the hatch, either through the addition of more fiberglass or a reinforcing bar or possibly a structure placed under the hatch to keep it rigid.
Any suggestinon will be appreciated.......

What's the dimensions of the hatch? Sounds like the current one has interior rot in the wood core.

The dimensions are 24" x 65".

A 24" span of glassed 3/4" plywood should not have that much flex. Again I highly suspect the plywood core has rotted and the entire hatch will need to be replaced. Not that hard of a job. Post some pics and we can help. I assume it is attached by one long stainless piano type hinge????
