CS 30 vs CS 395: the short version
- The CS 395 is the larger boat at 40.1 ft12.24 m LOA versus 30.0 ft9.14 m for the CS 30.
- The CS 395 is heavier, displacing about 60% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the CS 395 carries the more powerful rig (21.9 vs 18.5), favouring lighter-air performance.
- The CS 30 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the CS 30 rates better for offshore work (2.05 vs 2.17).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
