Cal 2-27 vs Cal 28: the short version
- The Cal 28 is the larger boat at 28.0 ft8.53 m LOA versus 26.6 ft8.10 m for the Cal 2-27.
- The Cal 2-27 is heavier, displacing about 12% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Cal 28 carries the more powerful rig (17.1 vs 16.9), favouring lighter-air performance.
- The Cal 2-27 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Cal 2-27 rates better for offshore work (1.96 vs 1.98).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
