C&C Redline 41 Mk II Information, Review, Specs

Sailing Performance & Handling

The Redline 41 Mk II is a product of the transitional era between the Cruising Club of America (CCA) and the International Offshore Rule (IOR), resulting in a hull that balances heavy-weather stability with surprising light-air agility. With a Displacement-to-Length (D/L) ratio of approximately 322, the boat is classified as a heavy-displacement vessel by modern standards, yet its performance is buoyed by an exceptionally high ballast-to-displacement ratio of nearly 48%. This high concentration of lead in the keel allows the boat to carry a generous sail plan (SA/D of ~17.1) even when the breeze freshens, maintaining a stiff, upright posture.

Handling is characterized by the "light yet responsive" feel common to Cuthbertson & Cassian designs. The Mk II improved upon the limited-run Mk I by incorporating a deeper, more swept-back keel and a slightly enlarged spade rudder for better tracking. As noted in editorial retrospectives by Good Old Boat, the addition of a "bustle" forward of the rudder helped smooth water flow, reducing the "squirrelly" tendencies often found in early spade-rudder designs of this size. Owners frequently report that the boat feels "eye-sweet" and close-winded, capable of pointing higher than many modern cruisers of similar length.

Interior Comfort & Variations

The interior of the Redline 41 Mk II reflects its dual-purpose racer-cruiser heritage, prioritizing seaworthiness and efficiency over the voluminous "condo-style" cabins of the modern era. The layout is classic: a V-berth forward followed by a head compartment, leading into a main salon featuring a centerline table and opposing settees. Notably, the Mk II often includes traditional pilot berths situated above and outboard of the settees, a hallmark of 1970s offshore racers that provides secure sleeping quarters while underway.

Materiality focuses on warm teaks and functional fiberglass moldings. While the hull is typically solid fiberglass—diverging from the fully cored Red Jacket—the interior remains bright and relatively airy thanks to the low-profile cabin trunk. Variations between hulls are common, as many were semi-customized for specific owners, though the primary sibling model is the Newport 41, which utilized the same hull mold but often featured different deck layouts and interior finishing standards. In 2014, C&C revived the name for a Mark Mills-designed Redline 41, though that modern IRC racer shares only the name and brand spirit with the original Mk II.

Popular Mentions & Media

The Redline 41’s cultural footprint is inextricably linked to the 1972 SORC overall victory of the Mk I prototype Condor. While Condor was technically a Mk I, its dominance against 85 of the world's most competitive yachts established the Redline series as a global force. This victory was so significant it garnered coverage in major outlets like Sports Illustrated and The New York Times. Additionally, the Mk II prototype Bagatelle gained notoriety as a contender for the 1969 Canada’s Cup, cementing the design's pedigree in the Great Lakes racing circuit.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Redline 41 Mk II with a technical eye toward its composite construction and vintage hardware.

• Deck Core Integrity: Like many vessels of this era, the Redline 41 Mk II utilizes a balsa-cored deck. Moisture intrusion around stanchion bases, chainplates, and mast steps frequently leads to delamination and core rot, requiring significant reconstruction.
• Rudder Blade Maintenance: The spade rudder is also balsa-cored and internally braced with steel. These units are prone to water absorption and internal corrosion of the rudder post or internal "tang" welds. Rebuilding the rudder with closed-cell foam is a common and recommended upgrade.
• Mast Step Corrosion: The aluminum mast sits on a steel or fiberglass reinforced step. Over decades, galvanic corrosion or structural compression can occur, especially if the boat has been raced hard with high rig tension.
• Hull Blisters: While C&C hulls are generally robust, some hulls from the late 60s/early 70s have shown osmotic blistering. A thorough survey of the bottom is essential to determine if a barrier coat or peel is necessary.

Community & Resources

Owners of the Redline 41 Mk II are supported by a robust and knowledgeable community. The C&C Photo Album & Resource Center serves as the definitive technical archive for the brand, preserving original brochures and line drawings. Regional groups, such as the C&C Yachts Owners Association, frequently host rendezvous events in the Great Lakes and Northeast United States, where the majority of these hulls are still actively campaigned and cruised.

The Verdict

The C&C Redline 41 Mk II is a timeless performance icon that offers classic aesthetics and a legendary racing pedigree for the traditionalist sailor.

Pros

• Timeless Aesthetics: The raked bow and low freeboard remain among the most beautiful silhouettes in yachting.
• Superior Stiffness: A 48% ballast ratio provides excellent stability and safety in heavy weather.
• Light-Air Performance: Surprisingly fast in light winds compared to modern, beamier cruisers.

Cons

• Maintenance Intensive: Balsa-cored decks and rudders are high-signal areas for potential rot.
• Cramped for the Length: The narrow beam and pilot-berth layout offer less interior volume than modern 35-footers.
• Vintage Systems: Original plumbing and electrical systems typically require a full overhaul for reliable cruising.
