C&C 115 vs C&C 121: the short version
- The C&C 121 is the larger boat at 40.0 ft12.19 m LOA versus 37.8 ft11.51 m for the C&C 115.
- The C&C 121 is heavier, displacing about 24% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the C&C 115 carries the more powerful rig (24.1 vs 22.6), 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 115 rates better for offshore work (2.09 vs 2.14).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
