C&C 27 Mk IV Information, Review, Specs

History and Design

The C&C 27 Mk IV was in production from 1981 to 1982, with hull numbers ranging from 916 to 972. This model represented the final evolution in the original C&C 27 line, a series that saw several iterations (Mark I, II, III, and IV) while retaining largely similar hull forms. The design was overseen by Robert W. Ball, who served as C&C Yachts' chief in-house designer from 1973 to 1991, playing a significant role in shaping the company's fleet during a crucial period of its history. C&C Yachts, founded on a commitment to innovation, was known for pioneering lightweight construction techniques, including the use of balsa-cored hulls, which contributed to their yachts' stiffness and reduced weight.

While the fundamental hull of the C&C 27 remained consistent across the Marks, the Mk IV introduced several refinements. Notable changes included the forestay being set back approximately four inches, a modification implemented to better accommodate a bow roller. Auxiliary power was also upgraded to a two-cylinder Yanmar 2GM diesel engine. Internally, the Mark IV saw mostly cosmetic updates, transitioning from the earlier teak interior finishes to an off-white interior, though the basic layout remained unchanged from previous Marks. A significant design evolution for the C&C 27 series, applied to later models like the Mk IV, was the redesign of the rudder in 1974, which featured a constant chord length, increased depth, and a reduced sweep angle, enhancing handling.

Sailing Performance and Handling

The C&C 27 Mk IV, with a length overall of 27.86 feet and a waterline length of 22.86 feet, delivers a performance-oriented cruising experience. Her design ratios reflect a yacht capable of sprightly performance. With a sail area to displacement ratio (SA/Disp) of approximately 18.58, the Mk IV is well-suited for performing in lighter air conditions, making the most of gentle breezes. Her ballast to displacement ratio (Bal/Disp) of around 0.38 indicates a respectable level of stiffness, allowing her to stand up to a good breeze and maintain an upright stance, contributing to comfortable sailing. The displacement to length ratio (Disp/LWL) of approximately 205.78 positions the C&C 27 Mk IV squarely in the moderate displacement category, suggesting a balanced approach to design that prioritizes both performance and seaworthiness without being excessively heavy. Owners generally report that the C&C 27 series, including the Mk IV, sails well to its PHRF rating, highlighting its competitive nature.

Accommodations and Layout

Despite its compact size, the C&C 27 Mk IV provides practical accommodations for coastal cruising. While the interior layout remained largely consistent throughout the 27-foot series, the Mk IV specifically featured an updated off-white interior finish, a departure from the earlier teak. The typical arrangement for these models includes a V-berth forward, a marine head, a salon area often with opposing settees that can convert to berths, and a galley. While specific maximum headroom is not detailed in the specifications, the interior is generally considered sufficient for two adults to cruise comfortably, though it would be a tight fit for four. Storage is generally adequate for weekend or short-term cruising, and ventilation is typically provided by deck hatches and opening ports.

Owner's Perspectives

Owners of the C&C 27 Mk IV, like many C&C models, frequently praise its robust construction and dependable performance, often highlighting the boat's comfortable motion in various sea states. The enduring quality of these vessels is evident in the fact that many older C&C 27s are still actively sailed today, contributing to a vibrant owner community. A common maintenance issue noted by owners across the C&C 27 series, including the Mk IV, is the potential for original deck fittings to develop leaks over time, often requiring re-bedding to prevent water ingress. Overall, owners appreciate the C&C 27 Mk IV for its blend of proven performance, solid build, and classic design, making it a popular choice on the used boat market for those seeking a capable and engaging small cruiser.
