Rob Ball's design for C&C Yachts represents a brief but noteworthy chapter in late-era production sailing, with the Cc 27 Mk IV manufactured during a short two-year window from 1981 to 1982. This 28-foot masthead sloop demonstrates the period's emphasis on performance-oriented cruising, featuring a modern fin keel with spade rudder configuration that delivers responsive handling characteristics. Built with fiberglass construction, the Mk IV carries 2,116 pounds of ballast within its 5,500-pound displacement, creating a stable platform well-suited for coastal cruising and weekend adventures. The boat's 361 square feet of sail area provides adequate power for spirited sailing, while the comfort ratio of 18.26 indicates a design that prioritizes performance over pure cruising accommodations. With a capsize screening formula of 2.08, this yacht falls within acceptable limits for protected waters and moderate offshore passages, though it's primarily intended for coastal sailing. The hull speed of 6.41 knots reflects typical expectations for this size range, while the SA/Displacement ratio of 18.59 suggests good light-air performance without being overpowered in fresh conditions. For sailors seeking a well-balanced boat from C&C's respected lineage, the Mk IV offers proven seaworthiness in a manageable package.
