Mirage 27 vs Mirage 29: the short version
- The Mirage 29 is the larger boat at 29.0 ft8.84 m LOA versus 27.2 ft8.28 m for the Mirage 27.
- The Mirage 29 is heavier, displacing about 24% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Mirage 27 carries the more powerful rig (19.0 vs 16.7), favouring lighter-air performance.
- The Mirage 27 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Mirage 27 rates better for offshore work (2.10 vs 2.22).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
