Cygnus 20 vs Nonsuch 22: the short version
- The Nonsuch 22 is the larger boat at 22.0 ft6.71 m LOA versus 20.0 ft6.10 m for the Cygnus 20.
- The Nonsuch 22 is heavier, displacing about 426% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Cygnus 20 carries the more powerful rig (29.5 vs 16.7), favouring lighter-air performance.
- The Nonsuch 22 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Nonsuch 22 rates better for offshore work (1.99 vs 2.85).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
