Archambault A27 vs Orion 27-2: the short version
- The Archambault A27 and Orion 27-2 are close in length (27.4 ft8.35 m vs 27.3 ft8.33 m ).
- The Orion 27-2 is heavier, displacing about 111% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Archambault A27 carries the more powerful rig (25.3 vs 15.3), favouring lighter-air performance.
- The Orion 27-2 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Orion 27-2 rates better for offshore work (1.71 vs 2.33).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
