I imagine C&C did considerable testing to determine the strength of their
construction to evaluate laminate schedules and optimum core thickness. Do you
remember seeing any letters in your binders explaining the testing done, dat
FWIW, this prompted me to take a look at the book "Heart of Glass:
Fiberglass boats and the men who made them": and some info on Balsa is on
p122,

builders of balsa planks for stiffening hull sides and bottoms. When balsa

Great info and research; so, how did balsa go from "wonder" material to; "bad
stuff don't touch..."?
