1973–1985 · designed by Cuthbertson & Cassian · built by C&C Yachts
The C&C 30 was designed as a performance-oriented one-design and club racer with genuine offshore capability, aimed at sailors who wanted competitive racing without sacrificing the ability to weekend cruise. It reflects C&C's signature approach of blending IOR-era race geometry with production-quality construction. The boat earned a solid reputation in the Great Lakes and East Coast racing circuits and attracted owners who valued sail-carrying ability and speed over pure comfort.
This is a general read on the C&C 30 class — informed
background, not a verdict on any individual boat. Condition, refit history,
and how a particular hull was sailed and stored matter far more than class
reputation. Use it to know what to look for; for a read on a specific
listing, run a free FairKeel report on that boat.
Strong upwind performance and responsive helming characteristic of C&C's IOR-era design work — one of the faster 30-footers of its era in a breeze.
Solid build quality by Canadian production standards of the period; hull laminates are generally stiff and well-constructed when not compromised by osmosis.
Active class associations in Great Lakes region provide parts knowledge, racing community, and experienced owners willing to share maintenance information.
Bolt-on lead keel is straightforward to inspect and rebolt compared to encapsulated or iron configurations.
Known trade-offs
Balsa deck core is nearly universally compromised on surviving hulls — budget for full or partial recore on any boat that hasn't had documented deck work.
IOR hull form translates to a small, raceboat-biased interior with limited headroom, minimal tankage, and tight quarters for anything beyond weekend use.
Standing rigging on original-rigged hulls is well beyond service life; any offshore or serious coastal use requires a complete rig inspection and likely full replacement.
Osmotic blistering is endemic to the class and should be treated as a when-not-if condition; a blister-free hull has either been barrier-coated previously or is rare.
Resale market is thin and price-sensitive; a large refit investment is unlikely to be recovered at sale, making condition-at-purchase especially important.

Balsa-cored deck is the class's most common expensive problem. Chainplate bases, stanchion bases, and hardware penetrations are chronic water-ingress points. Tap the entire deck for soft spots before purchase; a saturated core requires either localized recore patches or full deck recore.
Standing rigging and mast steppriority: offshore, coastal, racing, weekending
On a 40+ year old boat, assume all original 1x19 wire is condemned. Check the mast step (keel-stepped; steps atop the keel through the coach roof) and surrounding structural knees for delamination and deterioration. Chainplate attachment points through the deck must be inspected from below for cracking and water tracking into the laminate.
Keel attachment and hull-keel jointpriority: offshore, coastal, racing
Bolt-on lead keel with a glassed-over joint on many hulls. Inspect for weeping rust streaks around the keel sump, soft laminate near keel bolts, and any movement under rocking. Keel bolt withdrawal test is standard protocol on any hull this age.
Hull bottom and osmotic blisteringpriority: offshore, coastal, liveaboard, weekending
1970s-era C&C hulls predate improved osmotic-barrier protocols. Blistering is near-universal on hulls that have spent time in warm or salt water. Severity varies from cosmetic to structural. Requires a dry-hull survey with moisture meter; barrier coat at minimum, full blister repair and epoxy barrier if structural.
Engine (original Atomic 4 or early diesel)priority: offshore, coastal, liveaboard
Atomic 4 gasoline engines on early hulls are now elderly and parts-scarce; many have been repowered with small Yanmar or Universal diesels of varying quality. Verify repower installation quality: engine mounts, exhaust routing, fuel tank material, and throttle/shift cable condition are all repower-era variables.
How it fits your plans
Offshore
Marginal for extended bluewater passages. The fin-keel spade-rudder configuration and IOR proportions give good upwind speed but modest range safety margins; suitable for coastal offshore passages in competent hands but not a first choice for extended ocean passages. Rig and keel integrity checks are non-negotiable before offshore use.
Coastal
A natural fit. Fast, responsive, and well-suited to day sailing and coastal racing in protected or semi-exposed waters. A well-maintained C&C 30 is an enjoyable coastal boat with enough performance to stay interesting.
Weekending
Good weekender for two people comfortable with a race-oriented interior. Berths are serviceable, galley is minimal. Owners who value performance over comfort tend to be satisfied.
Racing
This is where the C&C 30 shines. PHRF-competitive in its class, active one-design fleets exist in some regions. A well-prepared hull with fresh rig is genuinely competitive in club and regional racing.
Liveaboard
Poor fit. Interior is compact and raceboat-prioritized; headroom, tankage, and storage are insufficient for full-time living.
