CS 30 vs Leigh 30: the short version
- The CS 30 and Leigh 30 are close in length (30.0 ft9.14 m vs 30.0 ft9.14 m ).
- The Leigh 30 is heavier, displacing about 14% 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 15.4), favouring lighter-air performance.
- The Leigh 30 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Leigh 30 rates better for offshore work (1.87 vs 2.05).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
