Nautor 43 vs Swan 39: the short version
- The Nautor 43 and Swan 39 are close in length (31.5 ft9.60 m vs 31.5 ft9.60 m ).
- The Nautor 43 is heavier, displacing about 84% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Swan 39 carries the more powerful rig (17.7 vs 12.9), favouring lighter-air performance.
- The Nautor 43 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Nautor 43 rates better for offshore work (1.73 vs 1.91).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
