Catalina 34 vs Coast 34: the short version
- The Catalina 34 and Coast 34 are close in length (34.5 ft10.52 m vs 34.3 ft10.46 m ).
- The Coast 34 is heavier, displacing about 32% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Catalina 34 carries the more powerful rig (16.0 vs 15.9), favouring lighter-air performance.
- The Coast 34 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Coast 34 rates better for offshore work (1.83 vs 2.06).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
