I came across the quote below on the internet, and wondered how the 1970s vintage 42s were doing as far as delamination in the sandwich hull construction, and the "deflections" mentioned in the quote.
"Until the mid-1980s, Krogen 42 hulls were fully cored with closed-cell PVC foam. After several boats built in the late 1970s and early ‘80s developed hull bottom deflections, the company switched to solid hand-laid fiberglass below the waterline."
