Cygnus 20 vs Niagara 35: the short version
- The Niagara 35 is the larger boat at 35.1 ft10.69 m LOA versus 20.0 ft6.10 m for the Cygnus 20.
- The Niagara 35 is heavier, displacing about 1374% 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 16.5), favouring lighter-air performance.
- The Niagara 35 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Niagara 35 rates better for offshore work (1.90 vs 2.85).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
