Floor : Hull : Liner Structural Build ?

[abl1111]

Been thinking about doing some floor work on my 23' Tsunami. A buddy and I were talking about what keeps the rigidity of these boats.

My vision of it ( up for discussion ):

Huge stringers are glassed to the hull. Potter Putty (PP) is then placed on top of the stringers and the the liner/floor is then placed on top of this Potter Putty, 'gluing' the liner/floor in place. The liner and the cap are then screwed in at the rubrail. Not sure how, if at all, the liner/ floor attaches to the hull near the vertical sides of the hull ? Also, below deck bulkheads play a critical role as well.

Sound right ?

I've viewed many SC floor job pix and it seems that the PP does not make contact with a lot of the liner/ floor as seen when the old floor is ripped out. You can see 30-40% of the PP with no contact at all. This seems like an achilles heal. Without ripping out the floor, how could you know of the integrity of this union of floor to stringers ?

Lastly, if you were to rip out a floor and replace, what is the better mouse-trap then the original PP / floor / stringer joint ? Where and what bulkheads are there that would need to be inspected ?

Just thinking of a winter project.
