1975 - 23' Tsunami --- Cork decks ?

[abl1111]

Are the decks in the floor of a 23' Tsunami cork ? And, if so, what they get soft, is it from delamination only or does the cork actually rot too ?

I have a few small areas, no more than a few 4-" areas, where the floor makes a creaking noise, like the deck/glass is slightly delam'd, but the core seems solid enough. Something to be concerned about? or chaulk it up to a 28 year old boat...

Thx,

Alan
