C&C 115 vs C&C SR 21: the short version
- The C&C 115 is the larger boat at 37.8 ft11.51 m LOA versus 21.1 ft6.43 m for the C&C SR 21.
- The C&C 115 is heavier, displacing about 755% 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 24.1), favouring lighter-air performance.
- The C&C 115 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 2.87).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
