I have not heard of any hulls that were balsa cored. Having said that however, the transoms are all cored, on all models.
Balsa coring is also typically used in decks on other sailboats, not hulls, again, this is the first I have heard of this and you would want to have it confirmed by a number of others. If moisture does intrude into the balsa, then there is risk of deterioration, delamination and other bad stuff.
One thing that I do know for sure is that O'Day stopped production of the DS series in 1990. Other companies continued after that, and today it is built by Cape Cod Shipbuilding.
