Design
Designed by Robert W. Ball, it has a fibreglass hull and a balsa core deck. It has a fixed fin keel and an internally mounted spade-type rudder. They were initially fitted with an Universal Atomic 4 gasoline engine but switched to a Yanmar diesel during the production of Mk III. Wheel steering was introduced in 1976.
The first four variants (or "Marks") of the C&C 27 are refinements of the original design; the C&C 27 Mk V is a different design.
It has a masthead sloop rig.
