C-Scow vs Nacra 20: the short version
- The C-Scow and Nacra 20 are close in length (20.0 ft6.10 m vs 20.0 ft6.10 m ).
- The C-Scow is heavier, displacing about 67% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Nacra 20 carries the more powerful rig (76.7 vs 46.1), favouring lighter-air performance.
- By the capsize screening formula the C-Scow rates better for offshore work (3.23 vs 4.65).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
