C&C 121 vs C&C SR 21: the short version
- The C&C 121 is the larger boat at 40.0 ft12.19 m LOA versus 21.1 ft6.43 m for the C&C SR 21.
- The C&C 121 is heavier, displacing about 958% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the C&C SR 21 carries the more powerful rig (26.3 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 121 rates better for offshore work (2.14 vs 2.87).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
