Archambault A13 vs Archambault A31: the short version
- The Archambault A13 is the larger boat at 43.0 ft13.11 m LOA versus 31.3 ft9.54 m for the Archambault A31.
- The Archambault A13 is heavier, displacing about 105% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the Archambault A31 rates better for offshore work (2.22 vs 2.24).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
