C&C 121 vs C&C 27: the short version
- The C&C 121 is the larger boat at 40.0 ft12.19 m LOA versus 27.9 ft8.49 m for the C&C 27.
- The C&C 121 is heavier, displacing about 165% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the C&C 121 carries the more powerful rig (22.6 vs 18.6), favouring lighter-air performance.
- The C&C 121 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the C&C 27 rates better for offshore work (2.08 vs 2.14).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
