Catalina 27 vs Seaward 25: the short version
- The Catalina 27 and Seaward 25 are close in length (26.8 ft8.18 m vs 26.8 ft8.15 m ).
- The Catalina 27 is heavier, displacing about 90% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Seaward 25 carries the more powerful rig (16.8 vs 15.2), favouring lighter-air performance.
- The Catalina 27 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Catalina 27 rates better for offshore work (1.86 vs 2.17).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
