1st post, looking for advice

Brace it up so it fits the shape of the deck exactly... Do not allow it to dry while bowed more than it should be...

If the deck is flat, so should the plywood be...

Cut the cross braces so that they exactly match the profile of the deck... Screw the deck piece to them and check that the profile has not changed.... Glass the assembly...

Then install in the boat with 3/16" peanut butter troweled on just like you would a floor tile....

Pre cut bamboo poles a few inches over length can then be bowed into place to firmly support it from the bottom and you can add weight from above if needed.

You can test the bottom support and weight system before gluing it together to make sure it's gonna work out.

You can also drill several 3/4" holes in the repair panel on say 18" centers to allow for both relief of the epoxy peanut butter and to manually verify that the panel is flush with the glass above it.
