J/70 vs J/92s: the short version
- The J/92s is the larger boat at 30.0 ft9.14 m LOA versus 22.7 ft6.93 m for the J/70.
- The J/92s is heavier, displacing about 214% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the J/92s rates better for offshore work (2.25 vs 2.43).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
