About the Cc 27 Mk I Sailboat

Designed by Rob Ball and built by C&C Yachts from 1970 to 1972, this 27-footer represents an early example of the modern fin keel and spade rudder configuration that would become the standard for performance-oriented sailboats. With 167 hulls produced during its brief production run, the Cc 27 Mk I established C&C's reputation for building fast, well-balanced boats that could excel in both racing and cruising applications. The boat's specifications reveal a design optimized for spirited sailing performance. Her sail area to displacement ratio of 18.44 indicates good light-air performance, while the substantial ballast-to-displacement ratio of nearly 50% provides excellent stability and stiff sailing characteristics. The fiberglass construction with balsa-cored deck was relatively advanced for 1970, offering durability with reduced weight aloft. With a comfortable cockpit and reasonably spacious interior for her size, the Cc 27 Mk I suits coastal cruising and club racing equally well. Her moderate displacement and fin keel configuration deliver responsive handling and good upwind performance. The low comfort ratio of 17.61 and capsize screening value of 2.13 suggest she's better suited for protected waters and coastal sailing rather than extended offshore passages, making her an ideal choice for weekend cruising and local racing programs.
