J/22 vs J/70: the short version
- The J/22 and J/70 are close in length (22.5 ft6.86 m vs 22.7 ft6.93 m ).
- On sail area/displacement the J/22 carries the more powerful rig (24.6 vs 24.5), favouring lighter-air performance.
- The J/70 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the J/70 rates better for offshore work (2.43 vs 2.64).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
