My information is that Columbia decks have Balsa wood cores.
The surveyors use a moisture meter to measure any moisture trapped in
the core. They tell me that the deck will be soft and mushy if there is
moisture trapped in the balsa wood. There are other threads that suggest drilling small diameter holes from the cabin side into any supspect places.
You can go to " Columbia yacht owners association " for other advice.
