CS 30 vs CS 36: the short version
- The CS 36 is the larger boat at 36.5 ft11.13 m LOA versus 30.0 ft9.14 m for the CS 30.
- The CS 36 is heavier, displacing about 94% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the CS 30 carries the more powerful rig (18.5 vs 16.5), favouring lighter-air performance.
- The CS 36 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the CS 36 rates better for offshore work (1.84 vs 2.05).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
