Bristol 40 vs Ocean 40: the short version
- The Bristol 40 and Ocean 40 are close in length (40.2 ft12.25 m vs 40.0 ft12.19 m ).
- The Ocean 40 is heavier, displacing about 8% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Ocean 40 carries the more powerful rig (17.3 vs 15.3), favouring lighter-air performance.
- The Bristol 40 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Bristol 40 rates better for offshore work (1.66 vs 1.91).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
