CS 27 vs CS 50: the short version
- The CS 50 is the larger boat at 49.9 ft15.20 m LOA versus 27.0 ft8.23 m for the CS 27.
- The CS 50 is heavier, displacing about 352% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the CS 50 carries the more powerful rig (24.4 vs 16.3), favouring lighter-air performance.
- The CS 50 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the CS 50 rates better for offshore work (1.88 vs 2.04).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
