I guess it depends on if you place the stiffening board on top where you get full upward floatation push for the whole board surface- no "taco" effect. If board is placed below the foam, there wouldn't be much upward force and you might get some depression in the middle.
It sounds like the compartment for the bottom seat is just too big and loose. One thing that I used to tighten up on my ODC was shims cut from an old 1.5" closed cell pool float. The pool float material has just enough compressibility to make the whole thing snug, and thus can be worked in slowly after the main foam is put in. Pieces can also be glued on the ends of the existing foam with aquaseal, once the proper tension is found. You might need only a one end shim or two, depending on the looseness. Anyway, just another idea.

[quote TubeDude]Is the 'taco effect different if sitting in the seat on land vs on water?
[#0000ff]I don't know the exact physics equation that measures how much support and displacement you get while on the water...as opposed to setting up out of the water. But that is a factor and can be a big one.
Sounds like you are creative and have some options to try. Let us know if you are able to work out a satisfactory solution.
I don't know anyone who has a Fish Cat that old so it well could have some different dimensions.
