J/32 vs Marlow-Hunter 31: the short version
- The J/32 and Marlow-Hunter 31 are close in length (32.4 ft9.88 m vs 32.4 ft9.86 m ).
- The Marlow-Hunter 31 is heavier, displacing about 19% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Marlow-Hunter 31 carries the more powerful rig (17.9 vs 17.7), favouring lighter-air performance.
- The Marlow-Hunter 31 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the J/32 rates better for offshore work (2.04 vs 2.08).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
