Design and Construction
The traditionally raked transom catches the eye first. The designers used this deliberate throwback to lengthen the deck and cockpit while limiting the aft girth measurement penalized by the rule, as the designers intended. In plan view, the bow is full and the stern drawn in. In profile, the counter tucks up, and the sheer is beautiful.
A gentle curve from the hull into the forefoot indicates deeply V-ed sections. C&C paired a highly swept keel with a scimitar-shaped rudder, an arrangement the firm used across a long series of designs. Construction is solid fiberglass with wood trim, an internally mounted spade rudder, and a swept fixed fin keel.
With a length-to-beam ratio of 3.54 and a displacement-length ratio of 245, the C&C 39 belongs firmly to the moderate-displacement IOR school rather than the lithe CCA silhouette it replaced. The IOR-derived transom and girth compromises also date the hull form.
Rig, Performance, and Handling
For the same rating, the IOR envelope allowed the C&C 39 to carry a much larger rig than a Cal 40. Its I dimension is five feet taller than the Cal 40’s, while the foretriangle is almost 50 percent larger than the mainsail area. That large foretriangle allowed the boat to fly a huge spinnaker.
The result was a boat that was very fast in light air and far quicker upwind than the older CCA types. Period reviews found that she would demolish the Cal 40 in light to moderate winds. The tall-mast version carries a PHRF average of 105.
The deeply V-ed bow sections and swept keel gave the C&C 39 the manners of a true dual-purpose race/cruise boat. She also proved herself an excellent offshore cruising vessel.
Accommodations
Below, the interior is nicely laid out and considerably roomier than the Cal 40’s—a real benefit of the IOR-driven deck stretch. A subtle bubble superimposed on the house-top camber adds headroom aft. The arrangement also includes an expanded galley and pilot berths, both specifically praised by one reviewer.
The result balances race-cockpit practicality with cruise-friendly living space, without the compromises imposed by later charter layouts.
The Verdict
The C&C 39 had a small production run but earned an outsized reputation. It was a genuine IOR pioneer, trading the old CCA sluggishness for a towering rig, real speed, and a roomy, thoughtful interior.
With only 48 boats built, availability is limited. Gasoline Atomic 4 power also dates the design to an era that was moving toward diesel. Even so, its dual-purpose character and offshore credentials keep the C&C 39 relevant for sailors seeking a period-correct racer-cruiser.
Pros
- Among the first production boats designed expressly for the IOR rule, with a much larger rig than comparable ratings allowed
- Very fast in light air and markedly quicker upwind than CCA-era boats
- Roomy, well-planned interior with a headroom-enhancing house bubble and expanded galley
- Genuine dual-purpose race/cruise character and proven offshore-cruising ability
Cons
- Only 48 built, limiting availability
- Gasoline Atomic 4 power in an era moving toward diesel
- IOR-derived transom and girth compromises date the hull form
