Edel 540 vs Sanibel 18: the short version
- The Edel 540 and Sanibel 18 are close in length (17.7 ft5.40 m vs 17.9 ft5.45 m ).
- The Edel 540 is heavier, displacing about 25% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Sanibel 18 carries the more powerful rig (22.1 vs 18.1), favouring lighter-air performance.
- The Edel 540 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Edel 540 rates better for offshore work (2.68 vs 2.81).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
