CS 36 vs CS 40: the short version
- The CS 40 is the larger boat at 39.3 ft11.96 m LOA versus 36.5 ft11.13 m for the CS 36.
- The CS 40 is heavier, displacing about 10% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the CS 40 carries the more powerful rig (18.6 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 1.97).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
