CS 27 vs Edel 820: the short version
- The CS 27 and Edel 820 are close in length (27.0 ft8.23 m vs 26.9 ft8.21 m ).
- The Edel 820 is heavier, displacing about 16% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Edel 820 carries the more powerful rig (16.8 vs 16.3), favouring lighter-air performance.
- The Edel 820 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Edel 820 rates better for offshore work (2.02 vs 2.04).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
