Archambault A31 vs Suspens: the short version
- The Archambault A31 is the larger boat at 31.3 ft9.54 m LOA versus 30.4 ft9.25 m for the Suspens.
- The Archambault A31 is heavier, displacing about 14% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Archambault A31 carries the more powerful rig (24.4 vs 22.1), favouring lighter-air performance.
- By the capsize screening formula the Suspens rates better for offshore work (2.15 vs 2.22).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
