C&C 121 vs C&C 45: the short version
- The C&C 45 is the larger boat at 45.3 ft13.79 m LOA versus 40.0 ft12.19 m for the C&C 121.
- The C&C 45 is heavier, displacing about 31% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the C&C 45 carries the more powerful rig (24.8 vs 22.6), favouring lighter-air performance.
- The C&C 45 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the C&C 45 rates better for offshore work (2.06 vs 2.14).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
