Sources disagree on first year — left blank rather than guessed.
All-new design that replaced the earlier C&C 35. Start year disputed (1982 vs 1983); built through 1987. Keel/centerboard version: 4.16 ft up / 6.4 ft down, 12,150 lb displacement, 5,700 lb ballast. Hull coring: owners describe it as a cored boat and Practical Sailor says C&C's 35-foot and larger boats of the period have balsa-cored hulls. Holding 24 gal is owner-reported. Engine hp (27) from a broker listing. Engine access is tight. Tender for its rig; better suited to coastal cruising and club racing than offshore.
Known problems for this model
-
Keel smile and keel sump damage hull
The keel-hull joint can crack (the C&C smile) and hard-raced or grounded boats have needed keel sump rebuilds; owners say US-built boats had more keel-area problems than Niagara-built ones.sailnet.com · forums.sailinganarchy.com
-
Stiff but brittle in groundings hull
An owner reported cracked stringers and keel-joint damage after groundings, and the designer is quoted as saying the stiffer build suffers more in a hard strike than earlier boats.forums.sailinganarchy.com
-
Rod rigging and aluminum chainplates rigging
Rod rigging needs periodic re-heading or replacement, and the aluminum chainplates can corrode against stainless turnbuckles after many years.sailnet.com · forums.sailinganarchy.com
-
Leaking long cabin windows deck
The long cabin windows commonly need resealing.sailnet.com
-
Core moisture at deck penetrations deck
Moisture-check the cored deck around fittings, chainplates and the cockpit sole; owners say the factory left core out around original through-hulls.sailnet.com · forums.sailinganarchy.com

-
Mast step rigging
Owners advise inspecting the mast step; one keel bolt sits under the mast, so keel work requires unstepping.sailnet.com · forums.sailinganarchy.com
-
Holding tank leak and shallow bilge plumbing
One owner found a leak at the top of the holding tank; the shallow bilge (especially on keel/CB boats) lets water spread, and a dripless shaft seal is suggested.sailnet.com · forums.sailinganarchy.com
Engines & parts
Yanmar 3GM / 3GM30F parts: good
Factory standard engine — you entered “Yanmar 3GM30F”
Very popular (used 3GM30Fs sell for $3,000+) and supported by a strong parts network. Cylinder head overhauls (valve seals, lapping, injector service) are a common, parts-supported repair.

Common problems (2)
-
Overheating at cruise rpm cooling
The 3GM30F has a known overheating tendency linked to its heat exchanger; owners also trace it to coked elbows, worn impellers, scaled heat exchangers or air in the raw water circuit. Some heat exchangers were replaced under warranty.forums.sailboatowners.com
-
Mixing elbow corrosion exhaust
OEM elbows corrode internally and should be inspected or replaced with stainless versions before they let water into the engine.practical-sailor.com · facebook.com
