Soggy Floor - help needed

Got it cleaned up

Any thoughts on building up the stringers adjacent to the muffler to the bottom of the floor height so the floor has less of a span? Any reason this was not done originally?

What you could do at this point is take 2by stock and notch it out 1/2 or 3/4 by 2 inches depending on how wide the "stringer" is next to the tank. Now the notched out area sits down on the existing stringer and extends up past deck, snap a chaulk line at desired height. Its kind of confusing but I hope this helps. Just one method of many. I'll try to post a pic of the concept but I think it may be tiny ( can't resize)

You could add what you need to the botom of the hatch to make it contact the middle stringers.

Nice to know I don't have to span the whole 56". Now to decide on core materials and methods. I think one reason the original failed is the way the top deck and bottom mat were joined. (Like the top image)Mine had separated at a few points and all of the wood was soggy.

Did my grinding and clean-up. 2 pails worth of soggy plywood and fiberglass! Then I laid out a plan. I would love some feed back from guys who have done this before I start. Here goes:

It starts with 3 pieces of Nidacore cut as shown by the dotted lines on the left diagrams.
I picked the Nidacore because it is light, they can ship it in 2'x4' pieces and three will work out perfect.(note two different thicknesses.) In the area where I thought I should use 3/8" there are stringers and fuel vents below.
I am hoping to eliminate the struts by using the 1" material.
The mahogany works for bolts for my leaning post and to allow me to use the least number of Nidacore and seams(I think)
Questions:
Will the 1" product be enough support for the floor?
Will the 1.5 oz cloth go around the corners okay?
Is but-seaming the Nidacore okay?Does the edge shown in the section make sense?
Should I try to put a slight crown in the floor to help drain water or go perfectly flat?
