Antrim 20 vs Independence 20: the short version
- The Antrim 20 and Independence 20 are close in length (20.4 ft6.22 m vs 20.5 ft6.25 m ).
- The Independence 20 is heavier, displacing about 12% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Antrim 20 carries the more powerful rig (24.0 vs 22.6), favouring lighter-air performance.
- The Independence 20 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Independence 20 rates better for offshore work (2.51 vs 2.61).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
