What is the composition of an 1988 Bullet, hull, sides and deck, i assume its that bulsa core (sp?)

Per Boating Mag:
"under the skin lies a layer of coremat, 3/4" of Baltek end-grain balsa (from keel to chime) and layers of bi axial and tri axial fiberglass material all held togother with alpha resin..."

As heavy as they are, there has to be some lead in there somewhere!!

Wave crushing Resin Buckets for sure !!

are they all composed of that bulsa, even in 88', ive heard some were not
