Bayfield 40 vs Islander 40: the short version
- The Bayfield 40 and Islander 40 are close in length (39.5 ft12.04 m vs 39.5 ft12.05 m ).
- The Bayfield 40 is heavier, displacing about 24% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Islander 40 carries the more powerful rig (17.8 vs 16.7), favouring lighter-air performance.
- The Bayfield 40 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Bayfield 40 rates better for offshore work (1.74 vs 1.84).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
