C&C 121 vs C&C 43-1: the short version
- The C&C 43-1 is the larger boat at 43.3 ft13.21 m LOA versus 40.0 ft12.19 m for the C&C 121.
- The C&C 43-1 is heavier, displacing about 46% 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 18.8), favouring lighter-air performance.
- The C&C 43-1 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the C&C 43-1 rates better for offshore work (1.85 vs 2.14).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
