CS 33 vs CS 40: the short version
- The CS 40 is the larger boat at 39.3 ft11.96 m LOA versus 32.7 ft9.96 m for the CS 33.
- The CS 40 is heavier, displacing about 70% 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 17.3), favouring lighter-air performance.
- The CS 40 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the CS 40 rates better for offshore work (1.97 vs 1.98).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
