Cal 20 vs Flying 15: the short version
- The Cal 20 and Flying 15 are close in length (20.0 ft6.10 m vs 20.0 ft6.10 m ).
- The Cal 20 is heavier, displacing about 169% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Flying 15 carries the more powerful rig (28.2 vs 20.0), favouring lighter-air performance.
- The Cal 20 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Cal 20 rates better for offshore work (2.24 vs 3.12).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
