Balboa 20 vs Tornado: the short version
- The Balboa 20 and Tornado are close in length (20.0 ft6.10 m vs 20.0 ft6.10 m ).
- The Balboa 20 is heavier, displacing about 397% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Tornado carries the more powerful rig (77.2 vs 20.4), favouring lighter-air performance.
- The Balboa 20 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Balboa 20 rates better for offshore work (2.37 vs 5.78).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
