Cal 25 vs Cal 27: the short version
- The Cal 27 is the larger boat at 27.3 ft8.33 m LOA versus 25.0 ft7.62 m for the Cal 25.
- The Cal 27 is heavier, displacing about 35% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Cal 25 carries the more powerful rig (18.2 vs 18.1), favouring lighter-air performance.
- The Cal 27 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Cal 25 rates better for offshore work (2.02 vs 2.05).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
