Kirby 25 vs Mirage 30: the short version
- The Mirage 30 is the larger boat at 30.0 ft9.14 m LOA versus 25.2 ft7.67 m for the Kirby 25.
- The Mirage 30 is heavier, displacing about 154% 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 17.3), favouring lighter-air performance.
- The Mirage 30 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Mirage 30 rates better for offshore work (2.10 vs 2.39).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
