Nautor 43 vs Swan 43: the short version
- The Nautor 43 is the larger boat at 31.5 ft9.60 m LOA versus 31.0 ft9.45 m for the Swan 43.
- The Nautor 43 is heavier, displacing about 47% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Swan 43 carries the more powerful rig (16.5 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 Swan 43 rates better for offshore work (1.65 vs 1.73).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
