AMF 2100 vs C&C SR 21: the short version
- The AMF 2100 and C&C SR 21 are close in length (21.1 ft6.43 m vs 21.1 ft6.43 m ).
- The AMF 2100 is heavier, displacing about 59% 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 19.8), favouring lighter-air performance.
- The AMF 2100 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the AMF 2100 rates better for offshore work (2.46 vs 2.87).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
