Bayfield 40 vs Columbia 40: the short version
- The Bayfield 40 and Columbia 40 are close in length (39.5 ft12.04 m vs 39.5 ft12.04 m ).
- The Bayfield 40 is heavier, displacing about 11% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Bayfield 40 carries the more powerful rig (16.7 vs 14.6), favouring lighter-air performance.
- The Columbia 40 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Columbia 40 rates better for offshore work (1.58 vs 1.74).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
