Properly protected wood is just fine in stringers, bulkheads, transoms,

But that wasn't what was being discussed. Hulls were.

THe hull is more than just topsides and bottoms, and the transom is
part of the hull also, last time I looked. Encapsulation and strength
of core material is the key but I agree that the bottom and hull sides
should ideally be uncored. If you do that however, you have to
stiffen them up in some other way, and increasing the thickness of the
glass laminate is an inefficient way to do it. The traditional way is
to add internal structure, typically encapsulated wood, another form
of composite construction.
