C-Scow vs Cal 20: the short version
- The C-Scow and Cal 20 are close in length (20.0 ft6.10 m vs 20.0 ft6.10 m ).
- The Cal 20 is heavier, displacing about 200% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the C-Scow carries the more powerful rig (46.1 vs 20.0), favouring lighter-air performance.
- By the capsize screening formula the Cal 20 rates better for offshore work (2.24 vs 3.23).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
