Need advice and suggestions.

[Bryan A.]

I have a Witewater 25 cuddy with a spongy front deck. The deck is not rotted but lacks support from underneath. It is plywood with glass on both sides. I was thinking of laminating one or two beams out of 1/4" x 4" mohaghany to get the shape, running that beam over a jointer to clean up the sides then epoxy it into to place. I would like to avoid some sort of pole or post in the middle of the cabin.

I'm looking for suggestions or better ideas before I begin. Everyting is removed on the interior. And I hope to start as soon as the temps rise in the Northeast. Here are some pics of the interior and exterior. You can see a few pieces of wood I put in there a few years ago but that was a temp fix and didn't work out, now I have a better plan. Also any suggestion on getting the glue residue off the surface. The whole interior was covered in grey fuzzy material which smelled bad. I plan on filling the weave and painting white for ease of cleaning.
Thanks in advance for your time.
