Archambault A40 vs Atlante: the short version
- The Archambault A40 is the larger boat at 39.3 ft11.99 m LOA versus 27.8 ft8.47 m for the Atlante.
- The Archambault A40 is heavier, displacing about 158% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Archambault A40 carries the more powerful rig (23.5 vs 13.7), favouring lighter-air performance.
- The Atlante scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Atlante rates better for offshore work (1.86 vs 2.06).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
