C&C 30 Mk II Information, Review, Specs

Sailing Performance & Handling

The C&C 30 Mk II is a notably more powerful vessel than the Mk I, characterized by a high-aspect masthead rig and a relatively light displacement-to-length ratio of approximately 190. With a Sail Area/Displacement (SA/D) ratio hovering near 19.5, the boat is exceptionally responsive in light air—a common trait of C&C’s "performance first" philosophy. Unlike many cruisers of its era that require a stiff breeze to get moving, the Mk II accelerates quickly out of tacks and maintains momentum through lulls.

In terms of sea-kindliness, the hull features a modern, flattened exit and a wider beam carried further aft than the original 30. This provides greater initial stability and a more spacious cockpit, though it requires more active sail trimming to keep the boat on its feet in heavy air. As noted in technical assessments by Canadian Yachting, the boat handles best when reefed early, as its large mainsail can create significant weather helm if the boat is allowed to heel past 20 degrees. It was typically offered with either a deep fin keel (5' 7") or a wing keel (4' 3") for shallow-water sailors; the fin keel version is widely regarded as the superior upwind performer, tracking with more precision and less leeway in a breeze.

Interior Comfort & Variations

The interior of the Mk II was a radical departure from the traditional linear layouts of the 1970s. By utilizing the 10' 6" beam and carrying it aft, Robert Ball was able to incorporate a genuine aft cabin with a double berth tucked under the cockpit sole, a feature largely absent in 30-footers a decade earlier. The layout is centered around a T-shaped galley to starboard and a dedicated navigation station to port—a rarity in this size class—which underscores the boat's "big boat" aspirations.

Materials used throughout the cabin include the signature C&C teak joinery, though the Mk II utilized more fiberglass liners than earlier models to increase structural rigidity and simplify maintenance. The main salon features a U-shaped settee and a drop-leaf table that can accommodate four adults comfortably. Headroom is generous, exceeding six feet throughout much of the cabin. While the Mk II was the primary production hull, C&C occasionally customized finishes for early buyers, and the "plus" era styling brought in more overhead hatches and portlights, resulting in a much brighter, better-ventilated cabin than the Mk I.

Known Issues & Buyer’s Checklist

Prospective owners should prioritize a few specific high-signal areas during a pre-purchase survey:

• Balsa Core Integrity: Like most C&C models, the 30 Mk II utilizes balsa coring in both the deck and the hull (above the waterline). Moisture intrusion around stanchion bases, chainplates, and the mast step is the most common "gotcha." High moisture readings in these areas can lead to delamination and significant repair costs.
• The "Smile": A common trait on many C&C fin-keeled boats is the "C&C Smile"—a hairline crack at the leading edge of the keel-to-hull joint. While often cosmetic, it can indicate that the keel bolts require tightening or that the floor stringers have experienced stress.
• Mast Step Corrosion: The mast is keel-stepped on a steel or aluminum plate. If water has sat in the bilge over time, galvanic corrosion can weaken the base of the spar or the step itself.
• Rudder Bearings: Owners frequently report play in the steering system as the bushings wear down. On a boat this age, the rudder blade should also be checked for "wicking" or moisture retention, which can lead to blistering or internal framework failure.

Community & Resources

The C&C 30 Mk II benefits from one of the most robust owner networks in the marine world. The C&C Photo Album & Resource Center serves as a vital technical wiki, housing original brochures, parts lists, and community-sourced solutions for model-specific repairs. Additionally, the C&C Yachts Association remains an active hub for owners across North America, organizing regional rendezvous and maintaining a database of hull-specific history.

The Verdict

The C&C 30 Mk II is a sophisticated, "grown-up" version of the 30-foot performance cruiser. It successfully balances the brand's racing heritage with the comforts required for modern weekend cruising. While it requires more vigilant maintenance regarding its cored construction, the reward is a boat that sails circles around contemporary "condo-marans" of the same length.

Pros:

• Exceptional light-air performance and acceleration.
• Modern, airy interior with a genuine aft cabin.
• High-quality teak joinery and robust deck hardware.
• Strong resale value and dedicated owner support.

Cons:

• Balsa-cored hull requires careful moisture monitoring.
• Can be "tender" and requires early reefing in heavy weather.
• More complex to maintain than simpler, solid-glass cruisers of the same era.
