Cal 24 vs Cal 39: the short version
- The Cal 39 is the larger boat at 38.7 ft11.79 m LOA versus 24.4 ft7.43 m for the Cal 24.
- The Cal 39 is heavier, displacing about 387% 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 19.8), favouring lighter-air performance.
- The Cal 39 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Cal 39 rates better for offshore work (1.91 vs 2.22).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
