Aloha 27 vs Cal 2-27: the short version
- The Aloha 27 and Cal 2-27 are close in length (26.5 ft8.08 m vs 26.6 ft8.10 m ).
- The Cal 2-27 is heavier, displacing about 29% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Aloha 27 carries the more powerful rig (18.1 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 2.17).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
