I have a carbon 70 without any issues in the hull (motors... not such good luck. Isn't it funny how some people call themselves "engine builders"). When I bought mine I called Cigarette just to get the real scoop and what I learned was that it was all marketing. The boat may be a couple hundred lbs lighter and that Cigarette wan't even able to tell me where the carbon was. I found mine on the sides from the rub rail down to the first chine, the transom, stringers in the engine compartment and the firewall. Cigarette said that most were like mine plus the deck. Very cool boat. Buy it cuz ya like it, not because its a carbon 70. FYI. Carbon will pin a moisture meter.
