1/4" of flex isn't all that much, but it really depends on the span of unsupported deck, the thickness of the laminate, etc. Have you checked with other Catalina owners to see if this is normal or have you done any moisture measurements, either via a moisture meter or by drilling exploratory holes to see if the core is wet???
If the flex is due to the deck being wet...what is the extent of the wet core/delamination?? Without knowing this, it is hard to say what would be the best way to fix it. If you have an area less than one square foot, you could try drilling holes and then letting the core dry out and then following up by injecting epoxy into the area. If it is larger than one square foot, I would highly recommend re-coring the deck there.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
