I have owned three Bigfeet: one built in 1986, one in 1996, and one in 2008. They were all built the same way*.
Yes, the interior walls are screwed to the sandwich shell, but the sandwich shell has the foam bonded in and paneling bonded to that before it is taken from the mold. The fiberglass by itself is too floppy to do that afterwards. Find one that has delaminated and check for yourself.
* Exception is that the earlier ones used extruded polystyrene while the later and current ones use expanded polystyrene. The extruded is harder to get and more expensive these days, but a better material structurally. Neither of these would be even considered for boatbuilding, rather you would use a structural foam like Airex, Divinycell, Corecell.
