I am looking at a 1980 30' C&C. That said, I know absolutely nothing about boats. How do I determine the model, mk1, mk11 ect.... Also I've seen a lot of 27 owners forums but no 30's. Any advise, input would be appreciated.
The 1980 C&C 30 is definitely the mkI version. The mkII is a completely different boat which was built in the mid to late 1980"s through the mid 1990"s. Check out the following link for lots of information about the classic C&C models. C&C's in general were very well constructed boats. The 30 mkI happens to be one of the most stable designs. I crew on one and can attest to the fact that they can handle some pretty rough conditions. Early models had an Atomic 4 then later on in the production run they came through with Yanmar diesels. Great boat.
