Etap 20 vs Etap 39s: the short version
- The Etap 39s is the larger boat at 39.0 ft11.88 m LOA versus 19.9 ft6.05 m for the Etap 20.
- The Etap 39s is heavier, displacing about 700% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Etap 39s carries the more powerful rig (22.0 vs 19.7), favouring lighter-air performance.
- The Etap 39s scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Etap 39s rates better for offshore work (2.05 vs 2.45).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
