Swan 39 vs Swan 41: the short version
- The Swan 39 is the larger boat at 31.5 ft9.60 m LOA versus 30.3 ft9.22 m for the Swan 41.
- The Swan 41 is heavier, displacing about 32% 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 15.3), favouring lighter-air performance.
- The Swan 41 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Swan 41 rates better for offshore work (1.66 vs 1.91).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
