Cal 39 vs Nautical 39: the short version
- The Cal 39 and Nautical 39 are close in length (39.0 ft11.89 m vs 39.0 ft11.89 m ).
- The Nautical 39 is heavier, displacing about 29% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Cal 39 carries the more powerful rig (17.8 vs 13.6), favouring lighter-air performance.
- The Nautical 39 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Nautical 39 rates better for offshore work (1.70 vs 1.94).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
