Well I am confused. 1980 was a crossing over point in the C&C line. My recollection is that they were still building a 33 and a 35. I don''t recall a 34 being produced until some time in the late 1980''s or early 1990''s. C&C''s of the early 1980''s were good coastal cruisers. At that point in their history they made reasonable club level racers. PHRF shows two 34''s (one the boat that I recall)and the other probably the boat in question. Its rating is a pretty slow ny modern standards of 147. The model is referred to as a 34M. It''s length is 33.50 feet overall with a waterline of 25.80 and a beam of 11.00. Its draft is 6.30 and she weighs 10090 lbs with 4360 lbs ballast. There is a shoal draft version which is slower and heavier.
C&C''s were reasonbably well built, certainly not Hinckley, but also not at the bottom of the barrel. At that time they were offered with a lot of gear optional and so you see them in a wide range of configurations from great racing hardware and nice cruising amenities to junky under duty deck gear and almost no ventilation or ports.
These were not intended as offshore boats and in the early 1980''s C&C''s were heavily influenced by the IOR racing rule, (which is not a good thing). Still and all C&C''s generally make good all around family cruisers and are better sailors than many boats of that era.
