C&C 30 Mk I Buyer's Guide
Shopping the used C&C 30 Mk I means weighing a 1973–1985 Canadian racer-cruiser built in volume — over 800 of them — against the specific configuration of any individual hull. The design's long production and steady engineering changes mean two boats bearing the same name can differ in rudder, mast step, engine, and boom height, so a buyer reads the hull number as much as the cosmetics.
Layouts on the Used Market
The Mk I is a 30-foot masthead sloop with a 10-foot beam and a cabin that carries standing headroom through the saloon. Forward are twin 6 ft. 4 in. V-berths with a head and vanity to port and a hanging locker opposite. The main cabin pairs a dinette with a settee, and the galley straddles the companionway with a refrigerator box and counter to port, the stove and sink to starboard. Early boats were tiller-steered; most survivors carry pedestal wheel steering, which does reduce cockpit sole room. The coach-roof dorade boxes and keel-stepped mast are constant across the run.
Equipment and Common Upgrades
Autopilots and dodgers are commonly fitted, and a chartplotter, cabin heating, and solar are often seen. A short-handed sail-handling setup is a less common owner upgrade. For a buyer, the meaningful clusters are energy and comfort: solar with heating extends shoulder-season cruising, while an autopilot paired with the helm-reachable primary winches reduces crew load on a reach. Diesel engine lineage matters more than gadgets — early Atomic 4 gas and rare Westerbeke units gave way to Yanmar diesels, and the hull number tells you which.
What to Inspect
The hull-to-keel joint often shows a slight "smile" at haulout, so check keel-bolt torque and sealant condition rather than treating it as harmless cosmetic cracking. Water saturation in the deck's balsa core near chainplates and other penetrations is a known minor issue; sound the deck around hardware and look for softness or staining. On hulls through 651 the oak mast step was vulnerable to weakening, replaced by an aluminum casting from 652 on — inspect the step and keel-partner structure on earlier boats.
Availability and Buyer's Takeaway
These boats turn up across the United States, Canada, the Netherlands, and Germany. For a used-market checklist: confirm hull number against rudder type (spade pre-1976, high-aspect after), mast step material (oak to 651, aluminum from 652), and engine (Atomic 4/Westerbeke early, Yanmar QM15 to 675, 2GM from 676); test the deck core near penetrations; and assess the keel joint "smile" for active movement. A well-kept Mk I rewards the buyer who shops by serial number.
