My experience with soft coring is that if it is soft (rotten) in decent areas, you can almost bet all or most of the rest is wet especially on a 45 year old boat if untouched. Its possible that could be a patch job though- moisture meter or exploratory holes through outer skin can help answer that. If you commit to replacing the deck/ sole then the stringers aren’t horrible and exploratory holes on those as well down low against the hull will tell you if the foam is saturated. Both of the Seacrafts (‘74 and ‘75)I have worked on sor far had foam that was soaked in about the bottom two inches ...but this one may not be? If you decide to remove the wet foam, seems most have cut open the top and left about a 1-2 inch border around the top surfaces. Dig out foam. Repour new foam . Shape foam flush on top . Glass over the tops and down the sides a few inches. Structuraly would think the stringers are fine if the foam is wet. Just lugging around a lot of water weight....and potential for freeze damage if in cold climate.
