I just read this on another post:
""""Actually the two 33s represent two generations of design and are very different boats. The 33 mark I is a second generation C&C, while the 33 Mark II and 30 Mark II are third generation.
All C&C designs (except Landfalls) are performance boats positioned towards to the racing end of the racer/cruiser spectrum, although they can be cruised if you are comfortable with the limited amenities for the size.
The second genration designs (and first for that matter)have solid glass hulls constructed like the proverbial brick shithouse
- I remember humming along at 7 knots under spinnaker
when we bounced our C&C 30 Mark I over a rock, actually knocked everyone of their feet!, leaving a fist-size knuckle in the leading edge of the lead keel. Took about 30 minutes to fill the knuckle the next Spring.
In the third generation boats C&C went for greater performance (and lowered costs) by coring hulls. These hulls can''t take abuse like the older ones, and if damaged, can become expensive repair
jobs for subsequent owners. No criticism of C&C here, just the risk of most cored bottoms.""""
Stating that the first generation 33 was solid. On the other hand a review by practical saolor (I believe it was) states that the 33 only used balsa on the forward panels of the 33 hull.
Still not clear.
Is there a way to obtain a build plan for the 33 mkI, mkII and mkIII?
Also how can one test a hull to check if its cored or not?
