Irwin 27 vs Santana 27: the short version
- The Irwin 27 and Santana 27 are close in length (27.1 ft8.25 m vs 27.0 ft8.24 m ).
- The Irwin 27 is heavier, displacing about 32% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Santana 27 carries the more powerful rig (19.0 vs 16.9), favouring lighter-air performance.
- The Irwin 27 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Irwin 27 rates better for offshore work (1.85 vs 2.11).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
