I would guess that some builders trying to stay solvent would have put less glass/resin in the boat to save money
. Their prices were established before the gas crunch. For instance, old Bayliners were noted to have real thick hulls prior to the crunch and then they got a lot thinner after. No way to know without determining hull thickness I suppose. My Rawson
30 built in '74 was way thinner than I thought it would be from previous information. When installing a through hull, I was amazed to find the hull only about 3/8+ thick within 2 ft of the keel! The boat took me to mexico
and back... after all the hull is just a skin to keep the water
out! or is it?
