Cal 24 vs Challenger 24: the short version
- The Cal 24 and Challenger 24 are close in length (24.4 ft7.43 m vs 24.3 ft7.42 m ).
- The Challenger 24 is heavier, displacing about 33% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Cal 24 carries the more powerful rig (20.1 vs 16.1), favouring lighter-air performance.
- The Challenger 24 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Challenger 24 rates better for offshore work (2.06 vs 2.22).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
