Irwin 27 vs Maxi 84: the short version
- The Irwin 27 and Maxi 84 are close in length (27.1 ft8.25 m vs 27.1 ft8.25 m ).
- The Maxi 84 is heavier, displacing about 20% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Maxi 84 carries the more powerful rig (17.7 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 1.94).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
