Catalina 22 vs Catalina 310: the short version
- The Catalina 310 is the larger boat at 31.0 ft9.45 m LOA versus 21.5 ft6.55 m for the Catalina 22.
- The Catalina 310 is heavier, displacing about 314% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Catalina 22 carries the more powerful rig (17.9 vs 16.7), favouring lighter-air performance.
- The Catalina 310 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Catalina 310 rates better for offshore work (2.11 vs 2.26).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
