Kirby 25 vs Mirage 24: the short version
- The Kirby 25 is the larger boat at 25.2 ft7.67 m LOA versus 23.8 ft7.26 m for the Mirage 24.
- The Mirage 24 is heavier, displacing about 17% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Kirby 25 carries the more powerful rig (21.5 vs 14.9), favouring lighter-air performance.
- The Mirage 24 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Mirage 24 rates better for offshore work (2.18 vs 2.39).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
